Apparatus for power generation by gasification of biomass with subsequent catalytic removal of tar compounds from the heating gas

Lower isoparaffins are synthesized by: (a) stage 1: synthesizing straight chain hydrocarbons by contacting the synthesis gas with a Fischer-Tropsch synthesis catalyst; and (b) stage 2: synthesizing isoparaffins in by contacting the straight chain hydrocarbons synthesized in the first stage, with a mixture of hydrogenation catalyst or solid acid catalyst. Synthesis of lower isoparaffins from synthesis gas that is a mixture of hydrogen and carbon monoxide involves: (a) stage 1: synthesizing straight chain hydrocarbons by contacting the synthesis gas with a Fischer-Tropsch synthesis catalyst; and (b) stage 2: synthesizing isoparaffins in by contacting the straight chain hydrocarbons synthesized in the first stage, with a mixture of hydrogenation catalyst or solid acid catalyst for hydrocracking and isomerizing the straight chain hydrocarbons.
