Abstract

Method of producing a hydrocarbon composition. In the method a biomass raw-material is gasified produce a raw syngas containing carbon monoxide, carbon dioxide and hydrogen, the hydrogen-to-carbon monoxide ratio being about 0.5 to 1.7. A part of the impurities is remove to produce a clean syngas which is fed into a Fischer-Tropsch reactor where a significant part of the carbon monoxide and hydrogen is converted to a hydrocarbon composition containing C 4 -C 90 hydrocarbons. From the Fischer-Tropsch reactor a hydrocarbon composition is recoved which mainly contains hydrocarbons which are solid or semisolid at ambient temperature and pressure and an off-gas of the Fischer-Tropsch reactor, comprising hydrocarbons which are gaseous at ambient temperature and pressure, is used for producing hydrogen gas; and the hydrogen thus produced is fed into the clean syngas. By introducing hydrogen into the clean syngas, the hydrogen to carbon monoxide ratio can be increased and by using offgas-produced hydrogen, the capacity of the process is significantly improved.
