This work reports a kinetic study of the pressurized gasification of a lignite char with CO,, H, and steam using a packed bed balance reactor (PBBR) system. The kinetics were studied under selected conditions in which the external and internal diffusion effects were negligible and chemical reaction
Kinetic studies have been carried out to elucidate the mechanisms of steam and CO, gasification of char and the interactions of these gasifying agents. The positive and negative influences of all product gases, excluding methane, were considered. An empirical approach was derived to describe the eff
