Abstract
This paper reports on the supported-K on gasification rate. Especially, the gasification kinetic rates of herbaceous and woody biomass-derived char have been revealed bymeasuring the rate of weight loss during its reaction with CO_2 as a function of temperature. The experimental results show that the high gasification rate of biomass char is appeared i.e., 2-14 times higher than that of raw-biomass char by directly supported-K.
