Description
Technical field
The invention belongs to novel save energy technical field, relate to a kind of coal additive and method that improves coke output and performance.
Background technology
The energy is the basic substance of the development of the national economy.The primary energy source coal of China is main, and the proportion of coal in the primary energy source demand is about 70%.In the coal total amount that China consumes, be directly used in direct incendiary coal such as thermal power generation, Industrial Boiler, Industrial Stoves and family's cooking stove according to statistics up to more than 85%.But owing to traditional cause China's energy supply and demand contradiction sharp-pointed with coal mode, low-level efficiency of combustion, efficiency of energy utilization is low, and energy technology falls behind, and the major industrial product unit consumption of energy country of emulating the advanced exceeds 20-50%.Simultaneously, because a large amount of directly burnings of coal have directly caused the serious coal-burning topsoil of China, be the main source of sulfurous gas in the atmospheric environment, oxynitride, flue dust, the environment of China has been caused havoc, also directly caused the serious burning type topsoil of China.From the whole service condition of coal, mainly comprise coal burning, coal destructive distillation, gasification of coal and coal liquefaction.Wherein, these four kinds of coals use in its process and all inevitably will that is to say that the yield from coal to the coal tar and the performance of coal tar will play a crucial role for the whole service efficiency of coal through this form of coal tar or semicoke.Therefore, exploitation can improve the technology of coal tar output and performance, plays an important role for improving resource utilization, coal overall utilization and alleviating environmental pollution.
The research of at present existing a large amount of clean energy-saving utilisation technology aspects about coal as purificant, catalysis burning-rate accelerator, purification agent etc., in the hope of improving the performance of coal, improves combustion position, reduces the discharging of combustion tail gas and lime-ash.Its mechanism of improving combustion position is to use oxygen to transmit theory and transfer transport theory ([1] Xiao Jianli, Kang Hua, Wang Zhenyang, the discussion of coal combustion catalyst catalytic mechanism, " coal technology ", 2002,21 (11): 73～75.[2] horse development, Zhao Hongbin, Dong Zhenqiang, coal combustion catalyst, " boiler technology ", 2000,31 (4): 5～7.[3] MckeeDW, Mechanisms of the aikalimetai catalysedgasification of carbon, " Fule ", 1983,62 (2): 170～175.[4] horse development, Guo Xingxiu, Li Jing, Han Ailing, the research of coal combustion catalyst and application, " heat energy is learned and engineering ", 2001,16 (6): 579～581.[5] Patrick JW, Walker AA, Study of the copper-catalyed combustion of carbon, " Carbon ", 1974,12 (5): 507～515.), and this class research mainly concentrates on the salt and oxide compound of basic metal, alkaline-earth metal and transition metal.Existing all kinds of coal catalyst and additive are to improving the performance of coal, improve combustion position, it is more or less all helpful to reduce the discharging of combustion tail gas and lime-ash, but because also there are many problems really in the aspects such as security, stability, economy and production operability of practical effect, use, cause negative factor to be difficult to greatly promote, also occur the good product of energy large-scale application so far.In addition, it is to lay particular emphasis on to reduce the coal point of ignition and improve coal low volatile content that these researchs have great majority, thus not too many to the raising of whole burning of coal efficient, and otherwise application seldom relates to for coal.
Field in coal consumption maximum---coal burning field, general theory is thought, in combustion processes, begin to be subjected to heated drying, volatile matter to be released to the most of burning-out of volatile matter from coal, approximately only account for 10% of coal total combustion time, and coke (remainder after coal drying, volatile matter disengage) accounts for the last 90% combustion time.On the other hand, the flammable matter content of coke accounts for 55～97% of coal total amount in the coal, the thermal value of coke accounts for 60～95% (" Theory of Combustion with pollute control " Cen Kefa, Yao Qiang, Luo Zhong determine, write the Gao Xiang, 2004 June the 1st edition) of coal total calorific value.Therefore no matter from combustion time, the quantity of burning with emit heat, the burning of coke all is topmost in the burning of coal process, can think that burning of coal mainly is the burning of coke.Therefore combustionvelocity, combustionproperty and the heat output of coke are determining combustionvelocity, performance and the heat of whole coal.That is to say that the output of coal tar and the raising of performance are significant for the energy efficiency of Application Areass such as coal burning, coal destructive distillation, gasification of coal and coal liquefaction.Based on the urgent present situation of the current energy of China and environmental protection, research and develop out the technology that can improve coal tar output and performance, just seem particularly important for improving coal resources utilization ratio, coal overall utilization and alleviating environmental pollution.

Know-why of the present invention:
The rock that coal is made up of multiple organic micropetrological unit, inorganic mineral and clay.Except containing water and mineral substance (ash content), it is flammable He can utilize composition mainly is carbon and hydrogen, and constitutes organic polymer together with contained a small amount of oxygen, nitrogen, sulphur.Coal is mixed by the organic polymer particle that contains C, H, O, N, S of a lot of different structures and dirt and is combined into whole.Between various organic polymer particles, often connect to bigger particle mutually by different hydrocarbon side chains.Be mingled with various impurity between the macroparticle, or leaving tiny hole and slit.
Coal is when being heated, and the moisture in coal grain surface and the slit evaporates gradually and becomes the exsiccant coal.The chain or the ring-type volatile hydrocarbons of easy fracture are come out, that is have volatile matter to discharge.The release rate of volatile matter is closely related with the characteristic of coal, Heating temperature and speed.If volatile matter that discharges and oxygen meet, just take fire when reaching ignition condition.Make after the difficult hydrocarbonize platform thing that decomposes is also separated out, volatilized in the coal when temperature continue to raise, similar that left is exactly is in graphite, the coke of being made up of a lot of tiny crystal grains.
Physics distillation and pyrolytic decomposition (and recombine) that the process that is subjected to the thermosetting coke of coal comprises component have only a decomposition course concerning coal itself.In pyrolytic process, inflammable gas is emitted with carbonic acid gas and water, according to the composition and the pyrolytical condition of coal, produces the condensable oils and the tar of different amounts, oxygenatedchemicals and hydrocarbon polymer are wherein arranged, and mainly are various aromatic compounds and the aromatic compound that contains branched structure.And remaining solid just forms coke.
The output of coke and performance be except with coal and production control process are directly related, also with coal in, especially the performance of surfaces externally and internally is directly related.Industrial practice shows, adds ZnCl in process of coking
2, AlCl
3, NaOH, H
3PO
4, atlapulgite, ferric oxide or gac be for reducing tar output, improves coal tar output and gas yield (H

4Except gac), improve the ratio of carbon-hydrogen in the low volatile, and can improve the performance (" conversion of coal ") of coke to a certain extent.On mechanism, mainly be by the metal ion that catalysis is arranged, comprise that the coal internal portion forms the metal ion of ash content, low volatile in catalytic pyrolysis and the reformation coal produces the hydrocarbon polymer of more amount, has reduced the output of tar.Because the generation of more lower molecular weight hydrocarbon polymer remains more high ratio of carbon-hydrogen compound and coke.Simultaneously, because the minimizing of the coal-tar middle oil material of coal, the coke ratio surface-area increases and partly forms the activation of the metal ion case of ash content, makes the performance of coke be improved.
From as seen last, suitably add metallic compound with catalysis and the compound that can excite the inner ash content metal ion of coal, just can effectively improve coke output and performance.Based on this understanding, the inventor has mainly carried out innovation on selection of catalysts and using method.Select the metallic compound and the method that these metallic compounds can be distributed to the coal surfaces externally and internally of excellent surface activating catalytic effect for use.As everyone knows, the catalytic effect of catalyzer is long-pending directly related with catalytic reaction surface, and therefore improving the reaction table area just can improve the catalyzed reaction effect.
