Renewable biomass and biomass-derived fuels could be readily gasified to produce a fuel gas rich in hydrogen. Among the biomass energy conversion schemes gasification produces a product gas, which based on its properties could be used either to co-produce value-added byproducts or hydrogen. As a readily renewable fuel, biomass may become a significant component in the global sustainable energy mix as fossil fuel resources begin to deplete. In addition, biomass utilization can expedite mitigation of greenhouse gas emissions and carbon sequestration cycles and promote "green" industries. Hydrogen or fuel gas produced from biomass could be readily used in most of the present natural gas or petroleum derived hydrogen energy conversion devices and also in advanced systems such as fuel cells.

The main objective pursued in this work is to investigate the fuel gas(rich in hydrogen) production  from biomass wastes  by applying the steam gasification technique. Characteristics of steam gasification of two kinds of biomass (rapeseed oil cakes and walnut shells) at different heating rate (in the order of 10-20°C s−1) and different metal oxide catalysts (CaO, MgO  and a mixture 50
