Abstract

The time constant of the intensive char circulating between the oxidizing zone and the reducing zone within the gasifier is of similar order of magnitude to the time constant of the dynamic change in surface oxide complex. The CO 2 gasification of char particles within the experimental fluidized bed gasifier are analyzed by a new model taking account of the dynamics of the surface oxide at surfaces of char particles.
