The aim of this study is to investigate gasification technologies and gasification of biomass for gaseous products. The gasification of biomass is a thermal treatment, which results in a high proportion of gaseous products and small quantities of char (solid product) and ash. At temperatures of approximately 873-1,273 K, solid biomass undergoes thermal decomposition to form gas-phase products that typically include H2, CO, CO2, CH4, H2O, and other gaseous hydrocarbons. Hydrogen gas was produced on a pilot scale by steam gasification of charred cellulosic waste material. The yield from steam gasification increases with increasing water to sample ratio. The yields of hydrogen from the pyrolysis and the steam gasification increase with the increase of temperature. In general, the gasification temperature is higher than that of pyrolysis and the yield of hydrogen from the gasification is higher than that of the pyrolysis.
