Gasification Reactivity of Coal Char in Gasification Syngas at High Temperature

摘要

1 The effect on gasification reaction in syngas: temperature>raw gas composition>coal amount.rn2 The coal reaction rate in the syngas is 49% and 69% of the coal reaction rate in pure gasification agent (H_2O, CO_2) in 1100℃ and 1300℃ respectively. The inhibition effect of CO and H_2 and competitive effect between H_2O and CO_2 reduce the reaction rate, and the effect of temperature is more significant in syngas than in pure gasification agent.
