Gasification and reforming technology that has a potential of resource recovery from solid waste has been developed because a major current. issue regarding waste management and reduction is the effective recycling of the waste including biomass. Hydrogen recovery is a promising way and may be extended to the use for fuel cells in the context of hydrogen society. Experiments are conducted by using a series of two reactor systems composed of gasifier and reformer equipped with catalyst bed. The results show that hydrogen can be obtained in a concentration of 50-60vol% in gas and 40mol/kg-feedstock (waste wood). The utilization of steam reforming Ni catalyst promotes hydrogen production and the material has the effect of decreasing operating temperature by about 200 degrees. The combined use of CaO with the catalyst can improve the performance of hydrogen recovery and also reduce the generation of by-products. Dioxins can form in the pyrolysis process even in oxygen-deficient conditions. However, the formation decreased according to an increase of temperature and of the thermal residence of gas and by the use of catalyst for decomposition.
