摘　　要：为了深入系统的研究煤焦与CO2及水蒸气的气化反应特性,综述了国内外对煤气化的主要影响因素、煤焦与CO2及水蒸气气化反应动力学、煤的结构特性在气化过程中的变化及CO2气化与水蒸气气化反应活性对比等方面的研究进展,并进行了总结。In order to study the gasification characteristic of coal char with carbon dioxide and steam further and systematically, this paper reviews the main influencing factors of gasification, the kinetics of coal char gasification with carbon dioxide or steam, the variation of coal structure during gasification and the comparison of reactivity between carbon dioxide gasification and steam gasification both domestic and abroad, and summarizes at last.
