Description
Technical field
The present invention relates to a kind of solid fuel anaerobic gasification hydrogen production process of near zero release.
Background technology
Fossil oil provides about 85% of world today's energy consumption, and still can rely on fossil energy, especially coal in for a long time from now on.Energy production of China and consumption structure are that according to measuring and calculating, even to the year two thousand fifty, the coal ratio also will account for about 58% based on coal, the system of providing multiple forms of energy to complement each other equally.But owing to fossil oil especially coal is being produced and utilized process to produce pollutent such as the SO that causes four big public hazards (atmosphere flue dust, acid rain, Greenhouse effect, depletion of the ozone layer) in a large number
x, NO
x, fine particle, heavy metal and CO
2Deng, be the one of the main reasons that causes atmosphere and other kinds type environmental pollution and ecological damage.Therefore development resource consumption is few, and there is very important meaning in the very low or almost nil coal energy utilization system of energy transformation efficiency height and total emissions.
Hydrogen has obtained day by day attention as the zero release energy.Produce the main source that hydrogen is hydrogen as energy source from solid fuels such as coals.So the technology of particularly producing hydrogen the coal from solid fuel of development near zero release has very big application prospect.
At present in the world part Study mechanism carry out correlative study, all propose coal zero release energy utilization system separately as U.S. GE energy and environment research company (GE-EER), U.S. zero release coal alliance (ZECA) and many research institutions such as (NEDO) of Japanese new forms of energy comprehensive exploitation mechanism, wherein promptly included hydrogen generating system.
Summary of the invention
The solid fuel anaerobic gasification hydrogen production process that the purpose of this invention is to provide a kind of near zero release.
It is that coal or biomass solid fuel are joined in the pressure cycling fluidized-bed gasification furnace, with water vapour as fluidized gasification agent to enter that vapourizing furnace carries out with CaO be the CO of receptor
2The receptor method is the partial gasification on basis, produces high-purity hydrogen through dedusting, purification.Semicoke and CaO and CO that vapourizing furnace produces
2Change the CaCO that reaction produces
3Be admitted to the circulating fluidized bed combustion stove together, burn and calcination reaction with the oxygen of sending into roasting kiln.CaCO
3Calcining is sent back to vapourizing furnace as CO after generating CaO again in roasting kiln
2Receptor.
Advantage of the present invention:
1) takes into full account the characteristics that coal shows in various conversion processes, in circle fluidized-bed gasification furnace, " high-activity component " of coal carried out the anaerobic gasification earlier, then " low activity component " sent into the burning of circulating fluidized bed combustion stove.The realization coal grading transforms, and reduces the requirement to gasification;
2) can realize the anaerobic gasification of coal, directly produce highly purified hydrogen;
3) be oxygenant with the pure oxygen in the roasting kiln, the product after the fuel combustions such as semicoke is highly purified CO
2, can directly handle or utilize.Simultaneously, because the pollutent growing amount of gasification is few, and easily handle as H
2S, NH
3Deng, and the coal ash slag that fluidized-bed gasification and burning produced has been proved to be the material of low hazardness, can fully utilize or simple process.So nearly zero disposal of pollutants that can implement device.
Description of drawings
Accompanying drawing is a solid fuel anaerobic gasification process for making hydrogen schema.
Embodiment
As shown in drawings, it mainly comprises a pressure cycling fluidized-bed gasification furnace, pressure or atmosphere circulating fluidized bed roasting kiln and device for transporting objects thereof.Coal or other fuel (as biomass) are sent into the anaerobic circle fluidized-bed gasification furnace of certain pressure, as vaporized chemical, thermo-cracking and partial gasification reaction take place in vapourizing furnace with water vapour.Thermo-cracking or the CH that gasification produced
4Be converted into CO and H by reforming reaction
2, and the CO in the gas phase also is converted into CO by water gas shift reaction
2The CO that each reaction is produced
2Then absorb to be solidified by CaO, the required heat of vapourizing furnace gasification reaction is also by CaO and CO
2The heat that carbonation reaction discharged provide.In the fuel the nitrogenous ammonia that produces in the dedusting refining plant, be removed, the hydrogen sulfide that fuel is produced in gasification is sent into and is oxidized to CaSO in the roasting kiln after absorb being generated CaS by CaO
4Fixing.Zero release fuel hydrogen hydrogen supply user after the udst separation (as fuel cell etc. efficiently).Coal or other fuel last low activity coke and absorb CO behind partial gasification
2The CaCO that the back produces
3Reach ash and sent into roasting kiln by device for transporting objects together, coke discharges CaCO with the pure oxygen reaction of sending into
3Decompose required heat.CaCO from vapourizing furnace
3Send back to vapourizing furnace continuation as CO through the CaO that calcining produces by device for transporting objects with Wingdale that replenishes adding or rhombspar
2Absorption agent.Roasting kiln fuel combustion and CaCO
3The CO that calcining is produced
2With the mixing high temp. gas of water vapour behind bootstrap system, the high-purity CO that its low temperature exhaust gas is obtained after condensation separation goes out wherein moisture
2Gas can be handled with comparalive ease as utilizing or landfill.The lime-ash that is produced is proved to be the material of low hazardness, can fully utilize or simple process.
