    摘要: A method for improving Fischer-Tropsch synthesis and recycling exhaust gases therefrom. The method includes: 1) transforming raw gas for Fischer-Tropsch synthesis using a water-gas shift reaction, transporting the transformed raw gas to a Fischer-Tropsch synthesis device for Fischer-Tropsch synthesis in the presence of a Fe-based or Co-based catalyst; 2) introducing exhaust gases from the Fischer-Tropsch synthesis device to a first pressure-swing adsorber for hydrogen recovery; 3) introducing the exhaust gases from 2) to a second pressure-swing adsorber for methane recovery; 4) returning part of the hydrogen obtained from 2) to 1) to mix with the raw gas, and transforming a resulting mixed gas to adjust a hydrogen/carbon ratio of the raw gas; and 5) introducing the methane in 3) to a methane reforming device to reform the methane whereby yielding syngas having relatively high hydrogen/carbon ratio, and transporting the syngas to 1) to mix with the raw gas.

    摘要: 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° 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.
