基于超临界水的性质及特点，重点介绍了目前超临界水-煤气化制可燃气等方面的研究现状，分别从反应物自身特性（水煤浆质量分数、煤样粒径等）与反应外部条件（气化温度、反应压力、催化剂种类、停留时间等）2个方面分析并总结了各因素对气化制可燃气的一般性影响规律。深入研究气化反应机理、在中低温环境下探索制取可燃气的最佳反应条件仍然是未来的研究重点。

Based on the properties and characteristics of supercritical water,current research status of combustible gas production by supercritical water-coal gasification (SWCG) is highlighted.General effect rules of various factors on the production of combustible gas are analyzed and summarized from two aspects:the characteristics of reactants themselves (concentration of coal slurry,particle size of coal,etc.) and external reaction conditions (gasification temperature,reaction pressure,catalyst type,residence time,etc.).Further study on the gasification reaction mechanism and the optimal reaction conditions to produce combustible gas at low and medium temperatures will continue to be the focus of future research.
