Description
Technical field
The present invention relates to oil shale resources technical field of comprehensive utilization, and in particular to one kind collection new gas heat carrier destructive distillation
With F- T synthesis liquefaction in the oil shale Efficient utilization method of one.
Background technology
The energy concerns countries in the world economic development and people's life level.With World Economics sustainable development, especially newly
Emerging economy is increased rapidly, and energy-consuming continues strong growth, and imbalance between supply and demand further deteriorates.Fossil energy is total in world energy sources
The principal status of public economy is occupied in body consumption, other energy especially new energy is quickly grown, but to be made substantial progress and needed time.
Since turning into net import of oil state for the first time from China in 1993, China's oil external dependence degree increased year by year, to the number in 2015
According to having risen to close to sixty percent.Under existing situation, itself potential energy industry project is greatly developed, accelerates energy storage
It is standby to build, China's oil external dependence degree is reduced, is the premise for ensureing China's economic society healthy and sustainable development.
" many coals, few oil, deficency " is China's energy resource structure feature.Although China's conventional oil and gas reserves be not rich
Richness, but unconventional energy resource rich reserves, Exploitation Potential are 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 (equivalent to 80,000,000,000 tons shale oil), equivalent to 5.4 times of natural oil recoverable reserves, its
Using quite varied, both incendivity generates electricity, but can destructive distillation oil refining, the waste residue produced in process can also be used to manufacture Building wood
Material.Therefore, the exploitation to oil shale are increased, to changing China's energy resource structure and improving China's energy deficiency present situation, are had
Very important strategic importance.
Existing more than the 80 years history of exploitation of the China to oil shale, related development utilizes technique relative maturity, but still
In the presence of many defects and weak point.Deficiency wherein present in gas heat carrier retorting technique has：(1) the bulk oil after crushing
The bulky grain oil shale of shale, only particle diameter between 16~75mm can be utilized by gas retort, the little particle of remainder nearly 20%
Oil shale is rejected, and causes serious energy resources to waste；(2) pyrolysis gas as gas heat carrier, it is necessary to individually heating furnace combustion
Burn partial thermal decomposition gas and be heated to certain temperature by pyrolysis gas is circulated, also cost is increased while wasting partial thermal decomposition gas；(3) gas
Body heat carrier destructive distillation oil refining, uses wet type coke discharging, the semicoke of institute's output is difficult to work with more due to, and energy utilization rate is only crude oil page
The 50%~60% of rock；(4) the solid waste semicoke that oil shale retorting process is produced contains lot of trace metallic element, partly waved
Volatile material, polycyclic aromatic hydrocarbons (PAH), oil, phenolic compound, sulfide and other materials, serious pollution is caused to environment.
Existing energy utilization patterns there are problems that high energy consumption, high carbon emission, high pollution,.Meanwhile, China's energy
Source resource bottleneck restriction becomes increasingly conspicuous, and the pressure of energy-saving and emission-reduction is increasing, and energy growth pattern is in the urgent need to transformation.For existing
The drawbacks of having using energy source technique, future source of energy will accomplish high in technological content, low in resources consumption, environment using technological development direction
Pollution less, it is good in economic efficiency, safety it is secure.
The present invention considers that future source of energy utilizes technological development direction, and essence is carried out on existing using energy source Process ba- sis
The improvement and innovation of property.Wherein, gasification is the important channel that solid fuel high-efficiency cleaning is utilized, at the same time, solid fuels
Change is also the major way for adjusting China's energy resource structure.After solid fuel gasification, it can both improve the utilization rate of fuel, reduce
CO、SO2Deng discharge, many clean energy resourcies can be made again；In oil shale gas heat carrier distillation process, big calorimetric is isolated
Vent one's spleen, its composition mainly includes H2、CO、CO2、CH4、C2H6Deng gas, this portion gas can be used as F-T after reforming conversion and close
Into high-quality raw material.Gas heat carrier cracking process, solid fuel gasification and F-T synthesis progress is integrated, it can not only solve
Respective weak point, can also make the energy be fully utilized, while oil shale utilization system liquid fuel yield
It will be improved significantly..
