Abstract: In this paper,about 150 years application and development history of coal gasification technologies in China was systematically reviewed. The introduction and application process of different imported coal gasification technologies in China was described based on three periods,i.e.,before the founding of new China,from the founding of new China to the reform and opening-up and after the reform and opening-up; The important progress and achievement in the process of hard exploration,systematic research and technology demonstration and application of China's coal gasification technologies before and after the reform and opening-up were summarized; The R&D process,technological features,application and latest progress of China's self-reliance coal gasification technologies were introduced; The domestic R&D progress of new gasification technologies,such as underground gasification,catalytic gasification,hydrogasification,supercritical water gasification and plasma gasification,were briefly reviewed. Additionally,this paper also summarized the experience in introduction,independent research and industrial application of China's coal gasification technologies,and the future development of coal gasification technology was also prospected from different aspects,such as unit investment reduction,system efficiency improvement,environmental friendliness achievement,collaborative treatment of liquid/solid organic waste,integrated development with information technology,new technology development and intellectual property protection.
