Pressurised steam gasification of lignin-rich fermentation residue via partial oxidation was implemented in a downdraft gasifier to obtain synthesis gas for liquid fuel production. We are developing the process to produce bioethanol via non-acidic pretreatment, saccharification and fermentation from woody biomass, leaving the lignin-rich residue with high moisture content. This study examined the partial oxidative gasification of the residue in pressurised steam at p = 0.99 MPa and T = 75G-900℃ for [H_2O]/[C] = 2-24 and equivalence ratio φ = 4-∞ in order to obtain the reaction condition for the high synthesis gas concentration. The high synthesis gas concentration of 66.9-70.6% was obtained at T= 900℃, [H_2O]/[C] = 6 and φ = 10-30.
