         Reaction Kineties of gasification of biomass-char in carbon-dioxide at atmospheric pressure was investigated in a thermobalance reactor using six kinds of biomass-char.From the experimental data, their mean specific gasification rates were determinded. The rate equation dx/dt = k(l-x) is proposed and used to evaluate the apparant activation energy and preexponen-tial factor for gasification reaction of six kinds of biomass-char in carbon-dioxide. Results show that the rate equation proposed is reasonable.
