Procedimiento y aparato para producir biocombustible líquido a partir de biomasa sólida

摘要

The present invention provides a method and apparatus for producing liquid hydrocarbonaceous product (1) such as biofuel from solid biomass (2), the method comprising: gasifying solid biomass (2) in a gasifier (6) to produce raw synthesis gas (3); conditioning of the raw synthesis gas (3) to purify the raw synthesis gas (3) to obtain purified synthesis gas (4) having a molar ratio of hydrogen to carbon monoxide between 2.5 to 1 and 0.5 to 1, preferably between 2.1 to 1 and 1.8 to 1, more preferably about 2 to 1, the conditioning comprising removing sulfur species from the raw synthesis gas (3) using a guard bed reactor (25); and subjecting the purified synthesis gas (4) to a Fischer-Tropsch synthesis in a Fischer- Tropsch reactor (5) to produce liquid hydrocarbonaceous product (1); wherein the solid biomass (2) is fed to the gasifier (6) using a lock hopper (10).
