Description

The low-temperature pyrolysis Apparatus and method for that is used for low-rank coal, resinous shale, petroleum residue
Technical field
The invention belongs to low-temperature pyrolysis equipment and the low-temperature cracking process in derived energy chemical field, particularly a kind of low-grade fossil energy.
Background technology
Thereby destructive distillation generally refers to solid organic matters and heat the process that pyrolytic reaction takes place under the state of secluding air, be broadly divided into low temperature, middle temperature, high temperature and ultrahigh-temperature destructive distillation according to different Heating temperatures, the industrial coal carbonization that is usually used in, and adopt low-temperature pyrolysis (500~650 ℃) can be widely used in low-rank coal and low-grade fossil energy such as resinous shale, petroleum residue, its product can obtain tar and the coal gas of high yield, and the remaining solid thing is that height contains the charcoal semicoke.Distillation process is for the treatment of existing very long history such as coal, resinous shale and petroleum residue, be example with the coal, its pyrogenation and carbonization technology started from for 20 beginnings of the century, low-temperature pyrolysis (pyrolysis) method for upgrading that once occurred a lot of coals in history, but having only of industrial achieving success is several, these methods are divided into outside external-heat, internal heat type and the interior heat hot hybrid by the type of heating of stove, can be divided into gaseous heat-carrier, solid thermal carriers mode again according to heating medium, whether contact with material and be divided into direct heating and indirect heating mode according to heating medium.
The 1950's, along with exploitation and the application of world wide oil, Sweet natural gas, pyrolysis of coal technological development speed slows down even pauses, but in the abundant country of some coal resources, never is interrupted the research and development to pyrolysis of coal.The seventies in 20th century, owing to three oil crisises in the world with to the clean energy growth of requirement, cause the attention to low-rank coal and resinous shale equal energy source pyrogenation and carbonization once again.Along with people pay attention to again to the research and development of pyrolysis of coal technology, develop some novel procesies successively.These novel procesies are directly burnt with coal and are compared, can produce the product of three kinds of different shapes of gas, liquid, solid, be actually heterogeneity in the coal is carried out the utilization of branch matter, in the pyrolysis product: hydrogenation of tar can be produced petroleum supplements and refinery cokes such as gasoline, diesel oil, residual oil; Coal gas can be used as the unstripped gas of clean fuel and inhibition and generation worker synthetic gas; Semicoke is the high-quality smokeless fuel, can be used as domestic fuel and calcium carbide, iron alloy, iron-smelting blast furnace blowing material, also is gasification raw material, the sorbing material of high-quality.Therefore the pyrogenation and carbonization of coal is the effective ways of the clean high-efficiency comprehensive utilization of coal, both can reduce the environmental pollution that fire coal causes, can improve low-rank coal comprehensive utilization of resources rate and value-added content of product again, have remarkable economic efficiency and environmental benefit, meet national industrial policies.
Abroad, states such as U.S., day, moral, Australia have extensively carried out research and test work, handle 1000 tons brown coal drying destructive distillation industry demonstration unit in one cover day of Wyoming State Gillette town Buckskin construction of coal mine as USDOE approval in 1989 and subsidy, go into operation in June, 1992, nearly 5 years have been moved, the liquid product that extracts from coal (CDL) is as oil replacement fuel, among the commercialization factory that year processing coal is 3,000,000 tons is designing and building.The Coalcon company of U.S. combinating carbide company has developed advanced on-catalytic hydropyrolysis technology, and pyrolysis temperature is 560 ℃, and hydrogenation pressure is up to 6.9MPa, and its liquids and gases productive rate height, product separate easily.
China begins to carry out the R and D work of pyrolysis of coal technology the 1950's.Units such as petroleum institute, Beijing, Dalian University of Technology, Zhejiang University, Shanxi coalification institute of the Chinese Academy of Sciences, Beijing coalification institute, Shaanxi coal industry chemical industry group have successively developed the pyrolysis of coal technology of different process, and have set up the large scale industry device.Beginning to build up a collection of at the beginning of the area, Yulin 90 is the internal heat type block furnace long-flame coal lump coal gas retort of representative with three river coalification companies, from single stove ability 3~50,000 ton/year, develop into present single stove ability 7.5~100,000 ton/year, the large-scale gas retort that single stove is 200,000 tons/year also puts into operation, has succeeded in developing the type of furnaces such as externally heated retort oven, two-part gas retort simultaneously.Total capacity reaches more than 2,600 ten thousand tons.
