A system for cogenerating gas-steam based on gasification and methanation of biomass, the system including a gasification unit, a shift unit, a purification unit, a methanation unit, and a methane concentration unit. A waste heat boiler is provided in an upper part of a gasifier of the gasification unit. The methanation unit includes a first primary methanation reactor, a second primary methanation reactor, a first secondary methanation reactor, and a second secondary methanation reactor connected in series. An outlet of the second primary methanation reactor is provided with two bypasses, one of which is connected to an inlet of the first primary methanation reactor, the other of which is connected to the first secondary methanation reactor. The second secondary methanation reactor is connected to the methane concentration unit.

Method and system for cogenerating gas-steam based on gasification and methanation of biomass

A method for cogenerating gas-steam based on gasification and methanation of biomass. The method includes: 1) mixing oxygen and water vapor with biomass, transporting the resulting mixture via a nozzle to a gasifier, gasifying the biomass to yield crude gasified gas, and transporting superheated steam having a pressure of 5-6 MPa resulting from sensible heat recovery to a steam turbine; 2) adjusting the hydrogen/carbon ratio of the crude gasified gas generated from step 1) to 3:1, and eluting the crude gasified gas whereby yield purified syngas; 3) introducing the purified syngas from step 2) to a methanation unit and transporting intermediate pressure superheated steam generated in the methanation unit to the steam turbine; and 4) concentrating methane of synthetic natural gas containing trace nitrogen and water vapor obtained from step 3) through pressure swing adsorption.

A method for recycling exhaust gas from Fischer-Tropsch synthesis. The method includes: 1) introducing raw gas to a shift reactor to conduct a water-gas shift reaction, and collecting shift gas; 2) introducing the shift gas to a Fischer-Tropsch synthesis device to yield a hydrocarbon fuel and exhaust gas, returning part of the exhaust gas as recycle gas; 3) introducing another part of the exhaust gas to a methanation reactor, allowing a methanation reaction to happen between the part of the exhaust gas and water vapor; 4) introducing a mixed gas product from the methanation reaction to a methane reforming reactor; 5) transporting the hydrogen and carbon monoxide resulting from the methane reforming reaction to a gas separator, separating the hydrogen and obtaining a mixed gas including carbon dioxide; and 6) returning the mixed gas including carbon dioxide to the methane reforming reactor.

Method for recycling exhaust gases from Fischer-Tropsch synthesis

A method for preparing a liquid hydrocarbon from syngas. The method includes: 1) mixing crude syngas from a biomass gasifier and a hydrogen-rich gas to yield a mixed gas; 2) dehydrating and decarbonizing the mixed gas for removal of moisture, carbon dioxide, and impurities, to yield a fine syngas; 3) introducing the fine syngas to a Fischer-Tropsch synthesis device in the presence of a catalyst, controlling a reaction temperature of the Fischer-Tropsch synthesis at between 150 and 300&#xb0; C. and a reaction pressure of between 2 and 4 MPa (A), to yield a liquid hydrocarbon and water which is discharged out of the Fischer-Tropsch synthesis device; and 4) returning 70-95 vol. % of exhaust gases from the Fischer-Tropsch synthesis device to step 3) to mix with the fine syngas, and introducing the resulting mixed gas to the Fischer-Tropsch synthesis device.
