Abstract
Hydrogen production from biomass raw materials and RPF (Refuse Paper and Plastic) using fluidized bed pyrolysis gasifier were investigated. Oxygen and steam were used for gasification and fluidizer. Ni based catalysts (G90LDP, ISOP) were estimated for tar cracking and hydrogen productivity. Tar concentration in pyrolysis gas decrease with increasing pyrolysis temperatures. In the case of using Ni based catalysts, 40〜70wt% tar materials in pyrolysis gas were decomposed into volatile mater, and the H_2 content in the pyrolysis gas is 45〜70vol%, dry base.
