“低碳、绿色、清洁、高效”是世界能源发展的主流，受环境约束、新能源和可再生能源发展以及经济波动等因素影响，2016年煤炭在全球一次能源消费中的比重为28。11%，达2004年以来的最低水平。煤炭在中国能源消费中的比重由2015年的63。66%下降至2017年的60。31%，创历史新低。综合考虑核能、风能和太阳能等其他能源的替代作用，预计到2035年，煤炭在中国能源消费结构中的比重仍将达到50%。煤炭清洁高效利用是煤炭产业绿色低碳发展的必然选择。本报告首先对国内外煤炭市场的现状及趋势进行了分析，其次重点分析了中国以超（超）临界发电等为代表的先进燃煤发电技术和以煤炭液化等为代表的现代煤化工技术的应用现状与发展趋势，最后提出了未来中国煤炭清洁高效利用“园区化、基地化、集约化、专业化”的发展方向。
Low-carbon，green，clean and efficient are the mainstreams of energy development in the world and affected by environmental constraints，new energy and renewable energy development，and economic fluctuations. In 2016，the share of coal in global primary energy consumption was 28.11%，which was the lowest level since 2004. The share of coal in China’s energy consumption fell from 63.66% in 2015 to 60.31% in 2017，the lowest ever. Considering the alternative role of other energy sources such as nuclear power，wind power and solar energy，it is expected that by 2035，the proportion of coal in China’s energy consumption will still be 50%. Therefore，the clean and efficient use of coal is an inevitable choice for the green and low-carbon development of the coal industry.
This article first analyzes the status and trends of domestic and international coal markets. Secondly，it focuses onthe advanced coal-fired power generation technologies represented by supercritical power generation in China and the current status of coal chemical technology represented by coal liquefaction. And eventually the paper puts forward the development directions of China’s clean and highly efficient use of coal in ways.
