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. Keywords 　biomass 　catalytic gasification 　hydrogen production 　　氢是一种极为理想的 2 次能源 , 具有燃烧热值
