The syngas (CO+H_2) required for liquid fuel synthesis was obtained by the oxygen-enrichment gasification of woody biomass by a bench-scale fixed-bed gasifier. The biomass feed rate was approximately 9 kg/h (dry basis). With an increase in the oxygen concentration from 22.8 to 30. 1 vol.%, the gas conversion on a carbon basis, CO concentration, and H_2 concentration increased from 91.9 to 96.2 C-mol%, 22.8 to 30.1 vol.%, and 16.8 to 23.7 vol.%, respectively. The concentrations of H_2S and COS derived from the woody biomass gasification were reduced to less than 5 ppb by using the scrubber and desulfurization tower. The hydrocarbon fuel was synthesized from purified gas using the Fischer-Tropsch (FT) synthesis reactor. 1.9 L of the hydrocarbon fuel per day from 13 kg of woody biomass (dry basis) was successfully obtained using a bench-scale biomass to liquids (BTL) plant including the gasifier.
