Abstract: Pressurised steam gasification of wet biomass in a fixed-bed downdraft gasifier was implemented to identify reaction conditions yielding the highest synthesis gas concentration and efficiency, and to examine the generation of sulphur compounds. The gasification of lignin-rich fermentation residue derived from a bench-plant for bioethanol production from woody biomass was investigated at p =0.99MPa and T =750–900°C for steam to biomass ratios (S/B) of 3.4–17 and equivalence ratios (φ) of 3.3–∞. The results showed that the highest concentration of around 70mol% was obtained at T ⩾850°C, φ =13 and S/B =3.4, the highest efficiency of 0.26 was obtained at T =900°C, φ =3.3 and S/B =3.4, and sulphur compounds were H2S and COS. For the production of BTL synthesis gas, pressurised gasification has the potential to convert the wet residue below 77.3wt.% moisture contents. [Copyright &y& Elsevier]
