The effect of ash impurities on coal gasification kinetics

摘要

On the base of the random pore model (cylindrical shape) the set of equations for describing of gasification kinetics of high ash content coal has been obtained. The influence of ash content on the development of pore surface area and rate of gasification process has been shown. The comparison of calculated and experimental data on kinetics of coal gasification and activation by steam has been carried out for different ash content and temperatures.
