Intrinsic kinetics and external diffusion of catalytic steam gasification of fine coal char particles

Xuantao Wu, Jie Wang

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 2,   Pages 415-426 doi: 10.1007/s11705-018-1725-8

Abstract: Catalytic steam gasification of fine coal char particles was carried out using a self-made laboratoryestimate the gas release rate at a low GFV, the transported effect of effluent gas on the temporal gasificationcoefficients ( ) and the effectiveness factors were determined at lower GFVs, based on the intrinsic gasificationAn intrinsic kinetics/external diffusion integrating model could well describe the gasification rateas a function of GFV, temperature and pressure over a whole gasification process.
