Comparison of Pyrolysis/Steam Gasification Characteristics of Woody Biomass in a Fluidized Bed Gasifier with Triple-beds

抄録

The pyrolysis/steam gasification characteristics of woody biomass were clarified by using a laboratory-scale hot model gasifier. As a result, the amount of H₂ formed by pyrolysis was increased due to the partial cracking by using porous alumina particles as a bed material. Additionally, the amount of H₂ formed was more increased by steam reforming of coke and steam gasification of char in steam gasification. Therefore, porous alumina particles are suitable for more hydrogen production.
