Abstract The technology of biomass gasification was developed and applied universally all over the world. However ,
the poor quality of fuel gas and much content of tar limited its further application. In the process of producing hydrogen from
biomass , zero CO2 emission could be realized. This technology has attracted the researchers around the world. In this paper ,
the general situation of biomass catalytic gasification to produce hydrogen was firstly introduced. The main chemical reac
tions that occured in biomass gasfication were listed in this paper. The principal factors , i. e. gasifying agent and catalyst ,
which affect the hydrogen content of gases were discussed. Then the representative flow for biomass catalytic gasification was
presented in this paper.
