Steam gasification of sawdust char was performed in a thermobalance reactor at high temperature. Gasification temperature was changed from to and steam partial pressure was 0.3, 0.5 and 0.7 atm. Three models of gas-solid reaction were applied to the reaction kinetics analysis and modified volumetric model was an appropriate model. Reaction control regime and diffusion control regime were distinct depending on the temperature. Apparent activation energy and pre-exponential factors for both of the regimes were evaluated and the effects of steam partial pressure were examined. concentration in the produced gas was two times higher than that of CO due to the gasification accompanying by the water gas shift reaction.
