Abstract: Nowadays，energy shortage and environmental pollution are the focus concerns in the world. As a clean energy，hydrogen energy has gained growing interest in recent years. Studies on thermo-chemical treatment and utilization of biomass have been extensively conducted，because it is an effective method for hydrogen-rich gas production. In this paper，the current status of studies on biomass pyrolysis and gasification is reviewed. The influences of different pyrolysis and gasification techniques，raw material characteristics，heat source types，reaction conditions，gasification agents and catalysts on hydrogen-rich gas production are discussed. The application and catalytic mechanism of catalysts in biomass pyrolysis and gasification are summarized. The main problems facing biomass pyrolysis and gasification for hydrogen-rich gas production are searching for catalysts with high efficiency and long life，and solving their deactivation problem by improving catalytic environment or pyrolysis/gasification techniques.
