洁净煤技术的研究现状及进展

hina is a country which has a big amount of coal production and consumption. It is a very important part to research and apply proper clean coal techniques; it’s also the main content of the national energy sources development strategy and has significant sense. The paper describes the background of research and the concept of clean coal techniques, introduces and analyzes the status of research and development of clean coal techniques with in China and abroad; in particular, describes the special features of Chinese clean coal techniques, such as underground coal gasification, industrial moulded coal, coal water slurry, coal liquefaction, clean coal united cycling energy production techniques. In this paper, the features of the clean coal techniques are shown, and the works which should be enhanced to develop the techniques in China are also pointed out.
