Experimental study on catalytic steam gasification of municipal solid waste for bioenergy production in a combined fixed bed reactor

► The catalytic steam gasification of MSW was experimentally investigated in a fixed bed reactor. ► The effects of operating conditions on gas yield and composition of MSW gasification were explored. ► The NiLaFe/γ-Al2O3 catalyst had a high activity of cracking tar and upgrading the gas quality. ► The optimal operating parameters for catalytic steam gasification of MSW were found in this paper.
