Kinetics on in-situ CO_2 removal gasification of woody biomass for hydrogen production in elevated temperature was fundamentally examined. From the experimental results using an autoclave, it is found that primary degradation, which is degradation of woody biomass, mainly controls degradation characteristics under 500℃ and that secondary degradation, which is conversion of tar to gas, strongly progresses above 500℃. The each kinetic parameter was obtained from these results. The activation energies were 21.4-34.9kJ/mol for the primary degradation and the activation energy for the secondary degradation was 29.3kJ/mol. Although they were relatively small value, it might depend on lower heating rate and presence of a CO_2 sorbent.
