Research Progress of Biomass Gasification for Hydrogen-rich Syngas

Hydrogen-rich syngas production from biomass gasification is considered as one of the most promising hydrogen production methods because of its clean and renewable raw materials and the diversity of product application. Catalysts play an important role in controlling the composition of biomass gasification products and the pyrolysis of tar. In this paper, the methods of hydrogen production from fossil energy, water decomposition, and biomass were reviewed, and the advantages, limitations, and existing problems of hydrogen production from biomass gasification were also analyzed. And, the influence factors of biomass gasification(gasification agent, reaction temperature, and catalyst) and the kinds of catalyst and its characteristics which used for biomass gasification(nickel-based, dolomite and alkali, and alkaline earth metal catalysts) were emphatically introduced. The research status of biomass gasification for making hydrogen rich syngas and catalysts in China and abroad were analyzed, and the prospects of the development of catalytic gasification for making hydrogen-rich syngas were discussed. The problems to be solved and the research direction were proposed.
