As a key technology for clean and efficient utilization of coal resources,coal gasification technology has developed rapidly in recent years. The important role of coal gasification technology in energy utilization and development in China was summarized,the current development context of coal gasification technology application in China was introduced,and the mainstream fixed bed gasification technology,fluidized bed gasification technology and entrained bed gasification technology were compared. The characteristics and applications of various gasification technologies were summarized,the experience and lessons of coal gasification technology application in China were pointed out，the future development trend of new gasification technology and mainstream coal gasification technology was forecasted. It is proposed that China′s coal gasification technology has gradually changed from extensive in the early stage to connotation intensive development stage. Under the background of "carbon peaking and carbon neutrality goals",the development direction of coal gasification technology mainly foucus on improving the overall efficiency of the gasifier,broadenning the adaptability of coal types,improving the production capacity of a single furnace of the gasifier,reducing the risk of shutdown,ensuring the reliability of the device,reducing the impact of gasification technology on the environment,and strengthening coal gasification technology integration with new coal chemical industry.
