摘要

The effect of coal bed thickness was studied and compared between steam and CO2 gasification. Despite using small amounts of coal sample, both gasifying agents' kinetics, i.e., steam and CO2, proved to be affected by bulk and interparticle diffusion. Comparison between the gasifying agents indicates that mass transfer effects are minimized when the raw material layer and particle size are smaller than 0.14 mm and 90 mu m, respectively.
