Hydrogen Production by Gasification of Biomass

Abstract

Gasification process for coal or waste plastics has been developed. Since in these conventional gasification technologies, partial combustion method is used, combustion gas is mixed in product gas. Therefore , in such partial combustion method, oxygen should be used for keeping high-concentration of valuable gas in th e product gas. However, if you use a raw materials of low heat value such as biomass, although oxygen is supplied to gasifier, concentration of valuable gas cannot be high. It suggests that a new concept which is different from conventional technologies should be established to obtain high-concentration valued gas from raw material s of low heat value. Internally circulating fluidized bed gasification is one of such new concepts of gasification
