Abstract
The invention relates to a method and apparatus for producing liquid hydro carbonaceous product () such as biofuel from solid biomass (). The method comprises a gasifying step for gasifying solid biomass () in a gasifier () to produce raw synthesis gas (), conditioning of the raw synthesis gas () to purify the raw synthesis gas () to obtain purified synthesis gas () having a molar ratio of hydrogen to carbon monoxide between 2.5 to 1 and 0.5 to 1, preferably to between 2.1 to 1 and 1.8 to 1, more preferably about 2 to 1, and subjecting purified synthesis gas () to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor () to produce liquid hydro carbonaceous product ().
