No.1-6 Kinetics of Char and Catalyzed Char Gasification at High Steam Particle Pressures with or without H₂ Presence

Abstract

We investigated the effects of high H₂ and H₂O (Steam) partial pressure on coal char and Ca loaded coal char gasification rate by using thermogravimetric apparatus. It is found that the H₂ gas existence strongly inhibits the char steam gasification rate. However, gasification rate of Ca loaded coal char was much higher than that of coal char gasification, and the inhibition of H₂ presence on gasification rate for Ca loaded coal char gasification was smaller than that for char gasification.
