Coal accounts for about 70％ of the primary energy sources in China.The environmental pollution and resources waste involved with coal processing and utilization are serious.It is therefore urgent to develop highly-efficient coal resources utilization theory and methods with low-carbon discharge.Based on our long-term basic research and technology development,the progress in beneficiation,cleaning,and transformation of coal,which includes dense phase fluidized bed dry beneficiation,deep screening of wet fine coal,micro-bubble flotation column separation,molecular coal chemistry,and transformation and separation of coal and its derivatives into value-added chemicals under mild conditions,is discussed.
