Description
Technical field
The invention belongs to coal chemical technology, is related to a kind of fine coal and faces hydrogen destructive distillation catalytic gasification device, specifically with fine coal
For raw material, the gas using active solid and containing hydrogen faces hydrogen destructive distillation (or pyrolysis) and catalysis gas as heat carrier, using fine coal
The pyrolytic gasification principle that change technology blends, produce gasification gas and/or dry distillation gas, while the technology of by-product light tar
Method, the cascade utilization of low-order coal, jet coal, bituminous coal etc. is realized substantially, synthesis gas, fuel are provided for downstream chemical industry synthesis device
The industrial chemicals such as gas, light tar.
Background technology
Since melting crisis from 2008, ballooning oil prices, which have stimulated world energy sources structure, to be changed rapidly, and the energy is various
Change just turns into a kind of trend, and the mankind will gradually reduce to oil degree of dependence, but being still of fossil energy such as oil, coal
The main source of work raw material.China's oil starvation, few gas, the energy resource structure feature of rich coal are doomed AND ENERGY RESOURCES CONSUMPTION IN CHINA, chemical products system
It is standby will be for a long time based on coal, coal mine machinery recovery percent is higher at present, and lump coal only accounts for 30% or so, major coal place of production
A large amount of cheap fine coal can not effectively utilize, more do not carry out cascade utilization.
Develop fine coal destructive distillation (pyrolysis) gasification technology, the cascade utilization for realizing coal be implementation national energy diversification strategy it
One.Simple fine coal destructive distillation or pyrolysis way can realize that the solid, liquid, gas sub-prime of fine coal utilizes, but solid product-coke breeze purposes
It is limited, slack market, into one of development bottleneck of pulverized coal pyrolysis industry；The fine coal distillation process developed at present, which is substantially, to be subtracted
Press operation, limited by compared with low operating pressure, High-temperature carbonization coal qi leel is seriously restricted from dedusting, simple fine coal destructive distillation
Further drawback be caused in tar, coal gas in a large amount of dust-ladens, particularly tar to tar deep processing containing a large amount of fine breezes it is very big
Difficulty, this is the two of the bottleneck for restricting this kind of technology commercialization；Simple fine coal destructive distillation is nearly all using cyclic ammonia water cooling coal gas
And tar, produce a large amount of phenol ammonia sewage and bring larger difficulty to subsequent purification processing, this is the three of the bottleneck for restricting fine coal destructive distillation.
The domestic patented technology applied substantially is coupled using fine coal destructive distillation (or pyrolysis), joint, complex method, and U.S. KBR
The powdered coal fluidized bed gasification technique of company's exploitation is coal gasification, and industrialization promotion is met difficulty, especially synthesis gas dedusting skill
What art was not met by industrialized production needs

Body heat carrier, gas volume, which is significantly increased, causes the investment increase of dry distillation gas cooling and purifying, and dry distillation gas and gasification gas are completely mixed
Conjunction causes synthesis gas largely containing other impurity such as methane, must carry out the separation such as methane or conversion when being used as synthesis gas again；
2) do not account for phenol ammonia sewage caused by retort section inside the device purified treatment, it is necessary to configure in addition at the phenol ammonia sewage of complexity
Reason system；3) do not account for coal gasification and destructive distillation is merged completely, simply to gasification and the combining of destructive distillation, compound or joint；4)
Output quality of coke tar is poor, and dust-laden is high, density is big, even if the density of middle low temperature tar is also greater than 1000.0kg/m3, can not meet
The requirement of downstream coal tar deep processing.
