" many coals, few oil, deficency " is China's energy structure feature.Although China's conventional oil and natural gas reserves do not enrich, unconventional energy resource rich reserves, Exploitation Potential is huge.Oil shale resources are exactly a kind of typical unconventionaloil pool energy, its oil shale reserves is about 2,000,000,000,000 tons (being equivalent to 80,000,000,000 tons of shale oil), be equivalent to 5.4 times of natural oil workable reserve, its application is very extensive, both incendivity generating, again can destructive distillation oil refining, the waste residue produced in the course of processing also can be used for manufacturing material of construction.Therefore, strengthen the exploitation to resinous shale, to changing China's energy structure and improving China's energy deficiency present situation, there is very important strategic importance.

China is to existing more than the 80 year history of the exploitation of resinous shale, and related development utilizes technique relative maturity, but still there is a lot of defect and weak point.Deficiency wherein existing for gaseous heat-carrier retorting technique has: the block resinous shale after (1) fragmentation, only have the macrobead resinous shale of particle diameter between 16 ~ 75mm can be utilized by gas retort, the granule wax shale of remaining nearly 20% is rejected, and causes serious Energy resources waste; (2) pyrolysis gas is as gaseous heat-carrier, needs independent process furnace combustion parts pyrolysis gas cycling hot to be vented one's spleen and is heated to certain temperature, also makes cost increase while waste partial thermal decomposition gas; (3) gaseous heat-carrier destructive distillation oil refining, owing to adopting wet type coke discharging, the semicoke of institute's output is difficult to utilize, and energy utilization rate is only 50% ~ 60% of raw oil shale more; (4) the solid waste semicoke that oil shale distillation process produces contains lot of trace metallic element, half volatile material, polynuclear aromatics, oil, phenolic compound, sulfide and other materials, causes serious pollution to environment.

There is the problems such as high energy consumption, high carbon emission, high pollution, low-conversion in existing Energy utilization patterns.Meanwhile, China's Energy resources 'bottleneck' restrictions become increasingly conspicuous, and the increasing pressure of energy-saving and emission-reduction is large, and energy growth pattern is in the urgent need to changing.For the drawback of existing energy utilization technique, it is high in technological content, low in resources consumption, low in the pollution of the environment, good in economic efficiency, secure safely that future source of energy utilizes technological development direction to accomplish.

The present invention considers that future source of energy utilizes technological development direction, and existing energy utilization Process ba-sis carries out substantial improvement and bring new ideas.Wherein, gasification is the important channel that solid fuel high-efficiency cleaning utilizes, and meanwhile, solid fuel gasification is also the major way of adjustment China energy structure.After solid fuel gasification, both can improve the utilization ratio of fuel, reduce CO, SO ₂deng discharge, many clean energies can be made again; In resinous shale gaseous heat-carrier distillation process, isolate a large amount of pyrolysis gas, its composition mainly comprises H ₂, CO, CO ₂, CH ₄, C ₂h ₆deng gas, this part gas can be used as the high-quality raw material of F-T synthesis after conversion of reforming.Undertaken integrated by gaseous heat-carrier dry distillation, solid fuel gasification and F-T synthesis, can not only solve respective weak point, the energy can also be made to be fully utilized, resinous shale utilization system liquid fuel yield also will be improved significantly simultaneously.。
