Description of the Invention: [Technical Field of the Invention] The present invention relates to a fuel element of a non-combustion type smoking article and a method of manufacturing the same. [Prior Art] In recent years, there have been articles which are different from smoking articles such as cigarettes or snow-cured tobacco which burn tobacco leaves, such as non-combustible smoking articles which do not burn tobacco leaves. These non-combustible smoking articles are composed of a fuel element containing carbon and a gas gel generating element which is a gas generating material which maintains a fragrant odor component on a suitable substrate. This kind of article is ignited by the fuel element at the tip end, and the gas gel (TPM) generated by the fuel element itself or the combustion heat of the fuel element is sucked by the gas gel generated by the gas gel generating element, so that the smoker can taste The aroma or odor contained in this gas gel. However, in the gas gel produced by smoking articles, there is a bad component, that is, carbon monoxide which is caused by incomplete combustion of the fuel element, and it is desirable to remove it as much as possible from the gas gel. In order to improve the incomplete combustion of fuel elements used in non-combustion type smoking articles, various techniques have been developed, and various investigations, reports, and patent applications have been made regarding the materials of fuel elements, the composition ratio and shape of materials. Patent Document 1 discloses a fuel element containing a catalyst composition containing metal oxides and/or metal ultrafine particles in order to reduce carbon monoxide in mainstream smoke. Further, Patent Document 2 proposes a method of arranging a CO oxidation catalyst adjacent to a combustion element to reduce carbon monoxide. Patent Document 3 suggests that the fuel element contains a heat source of metal carbide, metal nitride and metal mixture. Further, Patent Document 4 proposes a fuel in which a carbon fuel is substantially non-combustible at a temperature of 3,321,952, 2011,32,299 as a microporous layer and is coated on a carbon fuel. Further, Patent Document 5 proposes a method of reducing the ratio of incombustibles (calcium carbonate) contained in a carbon fuel to reduce carbon monoxide. Patent Document 1 suggests that a catalyst composition of a metal oxide and/or a metal ultrafine particle is used. However, the material of the iron oxide described in this document is expensive, which is disadvantageous for mass use, and the metal ultrafine particles are manufactured. Operation is difficult. Further, in manufacturing, it is necessary to smash the material, but the ultrafine particles cannot be entangled with the original material due to problems such as scattering during the formation of the fuel element. 'Patent Document 2 suggests that the carbon fuel has a catalyst layer disposed on the suction end surface and a gas gel formation source on the suction end surface of the catalyst layer. However, this method cannot provide sufficient heat to the gas gel generation source. There will be less gas gel formation and no function of smoking articles. Patent Document 3 suggests that 'the fuel element contains a heat source of a mixture of a metal carbide, a metal nitride and a metal as a catalyst, but the manufacturing cost of the metal carbide or the metal vapor is still applicable to a smoking article. Increase in manufacturing costs. Patent Document 5 proposes a method of reducing carbon monoxide by changing the ratio of incombustible materials (carbonic acid #5) contained in carbon fuel. However, this method is highly practical from the viewpoint of cost, but is caused by the continuation of combustion. The decrease in the number of times the puff is reduced, and the problem that the ignitability of the fuel element is lowered.

No. Hei. No. Hei. No. Hei. No. Hei. for purpose. The fuel element can be produced at a low price, and is provided with a oxidized sulphate reducing agent which is excellent in operability, can remove oxidized rabbits in a gas gel produced by non-combustible smoking articles, and has excellent ignitability. Further, it is an object of the present invention to provide a method for producing a fuel element which is non-combustion i and smoke σ σ. The production method does not reduce the carbon oxide reduction performance during the preparation process, and exhibits a good carbon monoxide low-reduction performance when sucking cigarettes. [Means for Solving the Problems] The present inventors have obtained a fuel element that solves the above problems by adjusting a formulation of a carbon monoxide reducing agent containing calcium aluminate particles having a specific surface area and a particle diameter. Further, a non-aqueous solvent is used in the preparation process to obtain a method for producing a fuel element which solves the above problems. That is, a situation of the present invention is to provide a non-combustion type smoking article fuel element which will contain aluminum represented by the formula (Ca〇)m(Al2〇3)n (but, 1/6gm/n $4/1). The calcium carbonate low carbon reducer is characterized as a carbon powder 'and a binder' as a fuel source. According to one aspect of the present invention, there is provided a method of producing a fuel element of a non-combustion type smoking article 321952 5 201132299, which method will contain a formula (CaO)m(Al203)n (but 'i/6$m /n$4/l) is a carbon oxide low-reducing agent of calcium aluminate particles having a BET specific surface area of from 2 m 2 /g or more to less than 20 m 2 /g, carbon powder as a fuel source, and a non-aqueous solvent kneading agent as a binder And it is extruded and shaped. [Effects of the Invention] According to the present invention, a non-combustion type smoking article fuel element can be produced at a low cost, and carbon monoxide in a gas gel produced by a smoking article of a non-combustion type smoking article can be effectively removed, and the ignitability is excellent. Further, the present invention can provide a method for producing a fuel element which does not reduce the carbon monoxide low-reduction performance during the preparation process and which exhibits a good carbon monoxide low-reduction performance when used. [Embodiment] The fuel element of the present invention contains a carbon monoxide reducing agent, a fuel source, and a binder of calcium aluminate particles having a BET specific surface area adjusted within a desired range. The fuel element of the present invention is used, for example, as a combustion heat supply source for a non-combustion type smoking article, so that the required complication is that the flammability burns for several minutes after ignition and generates sufficient heat when sucking the cigarette. Produces a gas gel. Each element component constituting the element (4) of the present invention will be described below. [Carbon monoxide depleting agent] - Carbon oxide depleting agent is to remove the material of 321952 6 201132299 which is produced by smoking articles (7). The carbon monoxide reducing agent of the present invention is obtained by mixing m-mole calcium carbonate with n-mole alumina at a ratio of 1/6$m/n$4/l and firing at i250 ° C to 1350 ° C. Sauic acid i bow is crushed and obtained. The calcium aluminate particles contained in the carbon monoxide reducing agent of the present invention have a BET specific surface area of 2 m 2 /g or more and less than 20 m 2 /g. Here, the specific surface area is defined as the ratio of the particle unit weight (g) to all the surface areas (m2). In general, the particle weight decreases as the particle size decreases, and the smaller the particle size, the larger the specific surface area tends to be. The surface of the carbon monoxide reducing agent (calcium aluminate) particles becomes a free radical of a carbon monoxide depletion, such as a releasing site of a superoxide anion radical (SUper〇xide ani〇I1 radical). In order to exert a good free radical release energy, it is desirable that the carbon monoxide reducing agent (calcium citrate) particles have a certain surface area. For example, when the BET specific surface area is less than 2 m2/g, the number of radical releasing sites is small, and the carbon monoxide reducing performance tends not to be sufficiently exhibited. On the other hand, the aluminate ruthenium particles have a certain size and a particle size which is ideal. When the particle size of the carbon monoxide reducer is at a nanometer size, problems such as scattering of particles during production may occur, and operation may be difficult. Further, the bet specific surface area can be obtained, for example, by using an automatic specific surface area/pore distribution measuring apparatus, and it is assumed that the calcium aluminate particles (specific gravity 2 g/cm 3 ) are solid balls having no surface pores and particles having a specific surface area of 2 m 2 /g. The particle size is 750 nm 'particles with a specific surface area of 2 〇 m 2 / g are 75 legs. Further, the carbon monoxide reducing agent of the present invention has a BET specific surface area, and even if 7321952 201132299 is in contact with the moisture-containing combustion gas, it does not decrease for a long period of time - the oxidized stone a has a low degrading property. Even if it has been poisoned by water for a while, it can still be placed in a temperature environment of 5〇〇t:= degrees to restore its carbon monoxide reduction function. The carbon monoxide reducing agent of the present invention may be one in which an iron compound is supported on the surface. The amount of the iron compound is preferably 'in general, and is preferably in the range of 5% by weight to 5.2% by weight based on the weight of the carbon: reducer. ° In order to carry the iron compound on the carbon monoxide reducing agent, the powdery suspension or suspension of the iron compound is applied by spraying, dipping, etc. on the surface of the calcium aluminate particles obtained as described above, and dried and fired. Method 'The iron compound is ideally added by a wet method using a non-aqueous solvent. Namely, the "iron compound supported on the particles is dissolved in a nonaqueous solvent." The iron compound may be dissolved in a nonaqueous solvent such as an organic solvent, and examples thereof include iron sulfate, iron chloride, and iron nitrate. An organic solvent can be used for the non-aqueous solvent, and the iron compound can be dissolved without particular limitation. Especially, it is ideal to use a network or ethanol. The use of a non-aqueous medium prevents the crystal structure of calcium aluminate which may occur when using an aqueous solvent = collapse or solidification. Therefore, the particles are not poisoned by water and lose two = chemical = low performance. Here, when an iron compound is added to the surface of the particles, the iron compound is more uniformly dispersed, and the function of the obtained carbon monoxide reducing agent is uniform. Further, when a nonaqueous solvent having a lower boiling point than water is used, the solvent is easily removed, and the addition treatment of the surface of the calcium aluminate particles can be quickly performed. Dissolve the iron compound in a non-aqueous solvent, mix it with calcium aluminate particles after firing, and

The iron compound is uniformly dispersed. If the dosage of the carbon monoxide reducing agent is too small, the effect of reducing the oxidation can not be sufficiently exerted, and if the dosage is too large, the decrease in combustibility and the decrease in the amount of generated gas are not preferable. The carbon monoxide depleting agent of the present invention is a replacement of 10 to 90% by weight based on the total weight of the fuel element, and desirably 1 to 60 parts by weight of the formulation. To reduce carbon monoxide in mainstream smoke by more than 1%, it is desirable to have a carbon monoxide reduction agent in the fuel element of 2% by weight or more. When the concentration is lower than 20/❶, the carbon monoxide in the fuel element is reduced. It is desirable that the agent is 4% by weight or more.

The dosing amount of the binder is preferably from 0.010 to 50% by weight, preferably from 0.1 to 0.75% by weight, based on 1% by weight of the fuel source. [Gas Glue Source] The gas gel source is a substance that generates a gas gel due to heat, specifically, a polyol such as glycerin, a tobacco component, water, ethanol, or the like. The gas gel source does not necessarily have to be formulated, but in the case of a formulation, it may be a ratio of 0.01 to 98% by weight, preferably 0.01 to 0.1% by weight, based on 1% by weight of the fuel source. [Non-aqueous solvent] The non-aqueous solvent is a substance which imparts appropriate viscosity to a raw material of a fuel element at the time of preparation of a fuel element to impart formability. Further, in order to prevent the calcium aluminate particles of the present invention from being poisoned, it is necessary to use a solvent other than water. A desirable non-aqueous solvent is an appropriate viscosity for the raw material of the fuel element, and it is preferable to use a solvent having a low boiling point depending on the easiness of the drying operation. Specifically, it is decyl alcohol, ethanol, propanol, acetone, etc., and ethanol is particularly preferable.

The non-combustible material is a ratio of the weight of the fuel source to the weight of the fuel, and is usually at least 98% by weight, preferably to a ratio of up to 8% by weight. [Forming Method of Fuel Element] The fuel element is, for example, a carbon monoxide reducing agent, a fuel source and a binder mixed in a powder form, and arbitrarily adding an incombustible material and/or a gas gel source and mixing them, and adding an appropriate viscosity to add To increase the formability, a non-aqueous solvent is added and kneaded, and this is obtained by extrusion molding. Further, each raw material is dissolved or suspended in a nonaqueous solvent in advance, and then mixed, and extrusion molding is also available. Further, in the fuel element, a plurality of air intake ports that are continuous in the longitudinal direction of the fuel element are provided. The air intake port is formed into an arbitrary shape by adjusting the shape of the die of the extruder at the time of extrusion molding. The resulting fuel element is 2 to 1 mm in diameter, 2 to 20 mm in length, 5 to 8 % in void ratio, desirably 4 to 8% in diameter, and 5 to 10 mm in length and 2 to 70% in porosity. [Specific use form of fuel element] The fuel element of the present invention is used as a combustion heat supply source of a non-combustion type smoking article. Non-combustible smoking articles include, for example, fuel elements, gas gel source elements, and gas gel removal elements (filters). Here, the 'fuel element is loaded in the cylindrical heat-dissipating element'. The gas-oil source element and the gas-gel removing element are loaded in a cylindrical member (barrel). The present invention describes the elements constituting the non-combustion type smoking article when the fuel element of the present invention is used in a non-combustion type smoking article. 11 321952 201132299 [The source of gas glue] The source of the gas glue is the heat supplied by the fuel element, which will produce the elements of the gas glue enjoyed by the user, and the gas glue source, the binder and the gas glue source fixture to make. The gas gel source and the binder are the same as those used for the fuel element described above. The gas gel source fixing material is a tobacco material such as tobacco leaves, tobacco, a residue derived from tobacco leaves and tobacco, a reconstituted tobacco sheet, an inorganic material such as alumina, calcium carbonate or zeolite, or a polymer organic such as cellulose. Compounds, etc. A representative source of the gas gel is glycerin as a gas gel source, leaf tobacco powder as a gas source fixative, and ammonium alginate as a binder. [Heat Dissipating Element of Fuel Element] The heat-dissipating element of the fuel element is used to prevent the heated fuel element from being exposed to the outside, and the presence or absence of the heat-dissipating element of the fuel element may be sufficient. The specific heat-dissipating element is composed of glass wool, rock wool, ceramic fiber or calcium silicate. [Cylinder] The cylindrical body is made of a wrap and a heat-insulating material, and is filled with a gas gel element and a gas gel removing element. At the same time, it is used to efficiently transfer the combustion heat of the fuel element to the gas source element to promote the generation of the gas glue. Further, in order to allow smokers to hold non-combustible smoking articles on their hands, they do not feel hot, but also impart a moderate heat-dissipating function. The wrapper is obtained by winding the gas gel source element and the gas gel removing element into a cylindrical shape, and the heat insulating material is further covered by the outer side of the wrap. Moreover, the inclusions are metals which have better heat resistance and better heat reflectivity such as aluminum foil than the 12 321952 201132299 wrap. On the other hand, the hot material contains, for example, paper. [Gase removal factor] The heat-dissipating material has a smaller thermal conductivity than the package. The gas-gel removal element is a so-called filter. The gas gel removal factor is used to moderately adjust the amount of gas gel inhaled by the smoker. Containing, for example, μ, gas gel removal elements can be

These additives may be added as they are carried on the filter or when the filter material is towed. Further, a substance such as a mint or the like may be added to the filter medium. Further, the gas gel removing element may have a hollow structure substantially without the gas gel removing ability, and may be omitted from the elements of the non-combustible smoking article. Non-combustible smoking articles may be provided with openings for taking in air in the case of smoking to dilute mainstream smoke constituents (e.g., carbon dioxide). Next, an example of the use of the fuel element of the present invention for a non-combustion type smoking article will be described with reference to the drawings. Further, the shape shown in the drawings is an example after all, and does not limit the aspect of the present invention. Fig. 1 is a cross-sectional view showing a non-combustion type smoking article in a state in which the fuel element 10' of the present invention is connected to the tubular body 50 having the ignition end portion 50a and the suction end portion 50b, and Fig. 2 is a first view. Part of the enlarged oblique 13 321952 201132299 view. Here, the fuel element 10 is loaded in the heat insulating element 20, and the cylindrical body 50 is filled with the gas gel source element 30 and the gas gel source removing element 40. The fuel element 10 is located closer to the ignition end portion 50a of the tubular body 50, and the gas gel removing element 40 is located adjacent to the suction end portion 50b of the non-combustion type smoking article. Further, the fuel element 10 is provided with a plurality of air intake ports 101 that penetrate in the long direction. Further, the tubular body 50 is formed of the wrapper 501 and the heat-dissipating material 502, and the gas-gel source element 30 and the gas-gel removing element 40 are wound into a cylindrical shape by the wrap 501, and the outer surface of the wrap 501 is broken. The hot material 502 is covered. The above non-combustion type smoking article is used in the following manner. That is, the fuel element 10 is first ignited to generate a combustion gas. Here, a part of the carbon monoxide generated in the combustion is decomposed by the carbon monoxide depleting agent in the fuel element 10. Next, the combustion gas flows into the cylindrical body 50 by the user's inhalation. The gas gel source element 30 loaded in the cylindrical body 50 is exposed to the combustion gas, and the scented gas gel is produced from the gas gel source contained in the gas gel source element 30. The gas gel thus generated is adjusted to a moderate amount by the gas gel source removing element 40, and is then placed in the mouth of the user. In this way, the user can taste the gas gel which has a low carbon monoxide content and contains a fragrance. Next, the characteristics of the carbon monoxide reducing agent and the fuel element of the present invention were verified by the following examples and comparative examples.

[Evaluation test of CO depletion performance of carbon monoxide reducing agent] Next, the CO depletion performance of the carbon monoxide reducing agent (samples 1 to 7) obtained by the above procedure was evaluated using a model gas containing CO (m〇del gas). The steps are as follows. A sample of 50 mg was taken and uniformly dispersed in 80 mg of glass wool, and filled in a quartz tube with an internal control of φ 8 mm. Inside the quartz tube, a mode gas containing 4,700 ppm of carbon monoxide, 160,000 ppm of oxygen, and a nitrogen-based mode gas, is circulated at 600 mL/min, and the portion filled with the glass wool is externally heated, and the temperature is raised from normal temperature to 800 ° C. The gas composition obtained at the outlet of the quartz tube was measured by on-line measurement using an IR analyzer (manufactured by HORIBA Co., Ltd.), and the CO concentration at 7 ° C was measured. The CO outlet concentration at 700 °C was divided by the c〇 concentration at the inlet of the quartz tube as the c〇 reduction rate in the model gas when heated at 700 °C. Further, the carbon monoxide depleting agent for samples 2 to 7 and the carbon monoxide reducing agent for carbon dioxide per particle (comparative sample 1) were also measured for the c〇 reduction rate.

From the comparison between the sample 5 and the samples 1 to 3, it is understood that as the amount of the iron compound added increases, the CO reduction performance is improved, and the increase in the dose of the iron compound is shown to decrease. That is, the results clearly show that the carbon monoxide reducing agent of the present invention is such that a small amount of the iron compound represented by iron (about 1.0% by weight) can exhibit sufficient CO reduction. 19 321952 201132299 Performance, iron compound content with iron When the amount of the element indicates more than 5.2% by weight and the formulation is added, there is a tendency that the dose is increased without increasing the CO depletion performance. Further, from the comparison between the sample 4 and the sample 5, it is understood that the CO reduction performance is improved as the area of the BET ratio table increases. Further, when the sample 4 and the samples 6 and 7 were compared, it was found that when the BET specific surface area was equal, m/n was 12/7, and better CO reduction performance was exhibited. [Preparation of Fuel Element] Next, the fuel element of the present invention was prepared using the carbon monoxide reducing agent (Sample 1) prepared by the above procedure. The steps are as follows. 40% by weight of the carbon monoxide reducing agent of the sample 1 was used as a fuel source of carbon powder (Carbon black, acetylene, 100% compressed, 99.5%, Wako Pure Chemical Industries, Ltd.) 50% by weight, as a binder of ethyl fiber 7 wt% of 素 (Wako Pure Chemical Industries Co., Ltd.), and glycerin (Glycerin, Kao), which is a gas source, is granulated by a granulator (DOME GRAN LAB DG-L1 Fuji Powder Co., Ltd.) After kneading, the obtained molded product was extrusion-molded by an extrusion molding machine (manufactured by Kitakura Co., Ltd.) equipped with an extrusion die having a diameter of 4.3 m, and the obtained molded product was dried in a dryer at 1 ° C for 2 hours. This was cut to obtain a fuel element having a diameter of 4.3 mm, a length of l 〇 mm, and a porosity of 21%. [Qualitative and Quantitative Method of Calcium Aluminate Salt Contained in Fuel Element] The thermogravimetric curve of the analysis result of the fuel element of the formulation sample 1 of the thermogravimetric measuring device (TG-DTA2000SR Brucker AXS) is not in the third Figure. Since the calcium aluminate particles are produced by sintering, they do not change due to heating. On the other hand, the fuel source and the binder will burn due to heating and will not remain in the residue. Thus, for example, the calcium aluminate ratio in the fuel element can be estimated, for example, from the 800 °C residue weight ratio. From Fig. 3, the weight ratio of the fuel element of the formulation sample 1 at 800 °C was 0.37. This is roughly consistent with the amount of calcium aluminate in the fuel element. In addition, the fuel element was heated in the atmosphere at 1000 °C for 1 hour, and the obtained residue was molded into a tablet shape, and then XRD (Rigaku RARBRU-200) was used for elemental analysis to confirm that there was a sour mom ((CaO) 2 (Al2). 〇3) 7) exists as a main component. (Measurement conditions for thermogravimetric analysis) Environment: air (5 〇 m / / min), heating rate: l 〇 ° c / min, temperature range: room temperature to l 〇〇〇 ° C. [Production of Non-Combustion Smoking Articles] The various fuel elements obtained in the above steps are filled in the heat-dissipating elements used in the commercially available products (Steamhot One), thereby replacing the fuel elements of another commercially available product (Steamhot One). The heat-dissipating element is a non-combustible smoking article that is filled with the fuel element of the present invention. [Measurement test of amount of TPM, amount of CO] Various non-combustion type smoking articles obtained by the above steps, with automatic cigarette smoker (puff) capacity: 1 mouthpiece smoke 55m / 'sucking time: 2 seconds per 1 mouthpiece Bell, the frequency of the mouth smoke: the condition of taking the cigarette once in 30 seconds.

The steps of producing a fuel element and a non-combustible smoking article. The obtained non-combustible smoking article is measured for the amount of τρΜ and the amount of CO produced in the same manner as in the example.

One is at 7 in U. (: The c〇 reduction rate in the model gas at the time of heating is the rate at which the CO oxidation reaction is expressed. The value is the size of the catalyst function of the carbon oxide depleting agent. That is to say, the CX) is low in the reduction rate. The CO oxidation reaction rate is high, and the _ media function is high. Further, the size relationship of the catalyst function is not affected by the test 321952 23 201132299 method as long as the reaction of the function of the catalyst is the same. That is, the co-reduction rate of the previous test using the model gas may also be reflected in the CO depletion performance of the carbon monoxide reducer in the fuel element. In other words, the carbon monoxide reducing agent of the present invention has a higher CO reduction rate than the model gas in the case of carbonic acid (than the teaching sample 1) at 70 CTC heating, and CO in the fuel element of the carbon monoxide depleting agent other than the formulation sample 1. The amount of production, which is significantly lower for the comparative example, is easily expected. In other words, this test is performed only on the non-combustion type smoking article of the fuel element produced by the carbon monoxide reducing agent of the formulation sample 1, but the fuel element produced by using the samples 2 to 7 in place of the sample 1 is also displayed. Good CO depletion performance (ie, less c〇 formation in the gas gel) is easily expected. [Example 2] Next, the influence of the amount of the calcium aluminate particles of the fuel component on the C 〇 reduction performance was reviewed. When 40% by weight of the formulation of the sample 1 of Example 1 was changed to 20% by weight of lanthanum/cerium and the calcium carbonate particles were changed to 20% by weight, the fuel element and the non-product were produced in the same manner as in the case of using the sample 1 in the first embodiment. Combustible smoking substance ° °. The amount of TPM produced and the amount of CO produced were measured in the same manner as in Example 1 for the obtained non-combustible smoking article. Examination of the CTPM amount 'c〇 quantity measurement test> The fuel element produced by the formulation sample 1 in Example 1 was subjected to the fuel element 'in the fuel element' of Comparative Example 1 and the fuel element composition of Comparative Example 1 and the fuel element was used. The results of analyzing the mainstream smoke components of the non-combustible smoking articles separately produced are shown in Table 5 below. Further, the relationship between the ratio of the amount of the calcium silicate particle preparation in the fuel element and the amount of co produced in the mainstream smoke is shown in Fig. 4. [Table 5] Carbon monoxide reducing agent (% by weight) Carbon powder (% by weight) Adhesive (% by weight) Glycerol (% by weight) TPM production amount (mg/support) Tar production amount (mg/support) CO production amount (mg /Support) Example 1 (Use sample 1) (Ca0)12(Al203)7 40 50 Ethyl cellulose 7 3 29 13.5 15.4 Example 2 (Ca0)12(Al203)7 20 (CaC03) 20 50 Ethyl fiber素 7 3 30.4 14.2 17.1 Comparative Example 1 (CaC03) 40 50 Ethylcellulose 7 3 31.3 14.7 18.9 From the results, it is understood that the non-combustible smoking article of the fuel element of the calcium aluminate particles of the present invention is used. Non-combustible smoking articles that do not contain the fuel element of calcium aluminate particles have a low reduction in carbon monoxide in mainstream smoke, and there is little change in the amount of TPM produced. Further, as is clear from Fig. 4, by increasing the ratio of the proportion of the calcium aluminate particles described in the patent, the carbon monoxide in the main stream can be reduced. [Review of Formability of Fuel Element] Next, the influence of the raw material of the carbon monoxide reducing agent and the solvent on the formability of the fuel element was examined. [Comparative Example 2] The molding of the fuel element was attempted in the same manner as in Example 1 except that the same amount of ammonium alginate was used instead of ethyl cellulose, and water was used instead of ethanol 25 321952 201132299. As a result, the fuel element of the desired shape cannot be formed under the same conditions. [Comparative Example 3] The molding of the fuel element was attempted in the same manner as in Example 1 except that water was used instead of ethanol. As a result, the fuel element of the desired shape cannot be formed under the same conditions. [Comparative Example 4] Fuel element molding was attempted in the same manner as in Example 1 except that calcium carbonate particles were used instead of calcium aluminate particles, and water was used instead of ethanol. As a result, the fuel element of a desired shape can be formed under the same conditions. [Comparative Example 5] The molding of the fuel element was attempted in the same manner as in Example 1 except that calcium carbonate particles were used instead of the calcium aluminate particles, and ammonium alginate was used instead of ethyl cellulose, and water was used instead of ethanol. As a result, the fuel element of a desired shape can be formed under the same conditions. [Investigation of Formability] The compositions of the fuel elements obtained in Formulation Sample 1 of Example 1 and the fuel elements of Comparative Examples 2 to 5, and the results of the evaluation of the formability of these were shown in Table 6 below. 26 321952 201132299 # [Table 6] Carbon monoxide reducer (% by weight) Adhesive (% by weight) Adding solvent (% by weight) during molding Formability of fuel element Example 1 (Use sample 1) (CaO)i2 (Al2〇3 ) 7 40 Ethyl cellulose 7 Ethanol 33 Comparable Example 2 (CaO)i2(Al2〇3)7 40 Alginic acid money 7 Water 33 Non-comparable Example 3 (CaO)12(Al2O3)740 Ethylcellulose7 Water 33 Non-Comparative Example 4 (CaC03) 40 Ethylcellulose 7 Water 33 Comparable Example 5 (CaC03) 40 Alginate VII 7 Water 33 can be used as carbon monoxide in the preparation of fuel elements as in Comparative Examples 2 and 3. The low-calorie calcium aluminate hydrates and condenses, and cannot be used for the dispensing of fuel elements. Further, in Comparative Examples 4 and 5, it was confirmed that when calcium carbonate was used instead of the acid I, the distilled water was used regardless of the type of the binder, and the fuel element was also formed. Therefore, it has been confirmed that the fuel element containing the calcium aluminate particles of the present invention can be formed regardless of the type of the binder, but the formability is lost when water is used. As apparent from the above, according to the present invention, the carbon monoxide reducing agent of the present invention can obtain a fuel element without changing the amount of TPM, and can reduce carbon monoxide in mainstream smoke. Further, by using a nonaqueous solvent such as ethanol, the fuel element can be molded using an extruder.
