Hydrogen storage alloys are currently used in the fields of automobiles, heat pumps, indoor air conditioning, etc., but hydrogen storage alloys such as LaNi 5 and Mg 2 are used.
Since there are many kinds such as Ni and the functions of the alloy such as hydrogen gas storage amount, discharge pressure and discharge temperature are different depending on the constituent metals, selection of the alloy is important for its use.

行なう方法を提供することを課題とする。Problems to be Solved by the Invention The present invention does not need to use a conventional hydrogenation catalyst at all by utilizing a specific hydrogen storage alloy in the hydrogenation reaction of edible fats or oils,
Alternatively, it is an object to provide a method for safely hydrogenating fats and oils by using a very small amount of hydrogen and utilizing a large amount of hydrogen at low pressure with a high hydrogenation rate.
以下本発明を詳しく説明する。 The present invention will be described in detail below.

か、あるいは水添率が小さいなどの欠点を有する。Furthermore, specifically, the hydrogen storage alloy used in the present invention has a decomposition equilibrium pressure temperature of 100 ° C. or higher, which is atmospheric pressure, of 200 ° C. or higher.
It is an alloy that releases hydrogen in the range of 0 ° C. or lower, and uses a metal hydride of the alloy to hydrogenate edible fats and oils kept at a hydrogenation reaction temperature of 120 to 200 ° C. On the other hand, a hydrogen storage alloy with a decomposition equilibrium pressure of 200 ° C or higher, which indicates atmospheric pressure, has an extremely small amount of hydrogen released in the hydrogenation reaction temperature range of 120 to 200 ° C. Or, it has a defect that the hydrogenation rate is small.

を有し、好ましくは、大気圧を示す分解平衡圧力の温度
が100〜200℃であるような合金が望ましい。However, a hydrogen storage alloy with a decomposition equilibrium pressure of 100 ° C or less, which indicates atmospheric pressure, releases hydrogen that has been occluded easily as a gas when heated at room temperature or with some heating, and a large amount of hydrogen becomes a gas when evacuated. I will release it. Therefore, at a temperature of 100 ° C. or lower, the metal-hydrogen compound of the alloy exhibiting an atmospheric hydrogen equilibrium pressure tends to reduce the amount of effective hydrogen consumed in the actual hydrogenation reaction. Further, hydrogen is easily released during handling of the powder, and therefore, it is dangerous and requires caution when using a large amount of metal hydride. Also, the exhaust and dehydration operations in the reaction tank, which are carried out for the purpose of preventing the oxidation of fats and oils, are impossible when the fats and oils and the hydrogen storage alloy are present in the same system. It is desirable to use an alloy which has drawbacks in handling and operation such as need to be carried out, and preferably has a decomposition equilibrium pressure temperature of 100 to 200 ° C., which indicates atmospheric pressure.
また、本発明で用いられる水素貯蔵合金は、平均粉末

なる欠点を有する。Further, the hydrogen storage alloy used in the present invention has an average powder particle size of 0.5 to 100 μm and is hydrogenated with hydrogen released from the powder. If the average powder particle size is 0.5 μm or less, it is difficult to produce industrially, and in addition to the drawbacks of high cost, there is also a problem that the process of separating the oil and fat and the powder during operation becomes complicated. is there. When the particle size of the powder is 100 μm or more, it is difficult to uniformly mix and stir the oil and fat, and as a result, the catalytic ability of the powder becomes low, and the hydrogenation reaction time becomes long.

水添反応を行う。In the present invention, the oil and fat (generally edible oil and fat) and the hydrogen storage alloy are put into a reaction tank, and the oil and fat are held at a temperature of about 120 to 200 ° C. for 10 to 360 minutes while stirring after deaeration, or
The hydrogen storage alloy is enclosed in a tray-type column that can cool the hydrogen storage alloy by a jacket method, and a hydrogenation reaction is carried out by circulating oils and fats held at about 120 to 200 ° C for 10 to 360 minutes.

しても良い。After completion of the reaction, hydrogen gas and hardened oil are recovered, the hydrogen storage alloy is cooled, and then hydrogen is recirculated to the hydrogen storage alloy to be repeatedly used for the next hydrogenation reaction. In addition, a small amount (up to 0.5% by weight) of the hydrogenation catalyst may be added in the water addition reaction, if necessary.
また、本発明は油脂に対する水素貯蔵合金の割合を５

と、油脂と粉末の混合液の濃度が高くかつ比重が大とな
るため、混合液の撹拌および輸送などの装置面が複雑と
なる欠点を有する。Further, the present invention sets the ratio of the hydrogen storage alloy to the fats and oils to 5
Hydrogenation is carried out at ˜70% by weight. When the proportion of the hydrogen storage alloy is 5% or less, the amount of effective hydrogen that contributes to the hydrogenation reaction is insufficient, and there is a drawback that a uniform and efficient reaction does not proceed.
When the ratio is 70% or more, the amount of hardened oil obtained in one water addition reaction operation is small, the operation efficiency is low, the concentration of the mixed liquid of fats and oils is high, and the specific gravity is high. Therefore, there is a drawback that the apparatus surface such as stirring and transportation of the mixed solution becomes complicated.
なお、本発明は実験装置の耐圧の関係上比較的低圧の

処理粉末なども本発明に使用可能である。Although the present invention has been studied in consideration of the operation at a relatively low pressure in relation to the pressure resistance of the experimental apparatus, the hydrogen pressure is 10 kg / cm 2
It is recognized in this industry that it can be applied under the above pressure. Further, as the hydrogen storage alloy, a plating powder, a surface-treated powder, etc. which are surface-modified for the purpose of improving corrosion resistance, thermal conductivity, etc. can be used in the present invention.
これら水素貯蔵合金は合金100g当り水素（H2）を１〜
4g吸蔵でき、その排出水素も圧力が低く純度の非常に高

いると良い。These hydrogen storage alloys contain 1 to 100% of hydrogen (H 2 ) per 100 g of alloy.
4g can occluded, because the discharge of hydrogen even pressure is very high nascent hydrogen purity low hydrogen the starting fat or oil (H 2)
It is preferable to use a hydrogen storage alloy in which 0.001 to 1.0% by weight is added.

上の安全性に優れている。さらに、さきに述べたような
上昇流棚段式カラムを用いる場合には、油脂と水素貯蔵
合金の濾過に対する負荷を大幅に軽減できるという操作
上の利点もある。As described above, when hydrogenation of fats and oils is performed by using the specific hydrogen storage alloy according to the present invention, there is no need to use a conventional catalyst such as nickel, or margarine can be efficiently used with a very small amount. It is possible to obtain a hardened oil that is suitable as a raw material oil such as oil and shortening. Further, the hydrogen storage alloy can store a large amount of hydrogen gas as compared with a conventional industrial hydrogen storage device, and can be used at a low pressure as described above, and therefore has excellent work safety. Further, when the upflow tray type column as described above is used, there is an operational advantage that the load on the filtration of the fat and oil and the hydrogen storage alloy can be significantly reduced.
