【摘要】 我国能源结构以煤为主,石油及相关产品供需矛盾日益突出,将煤炭进行转化以替代部分石油,建立煤基液态能源体系是目前重要方向。煤基液态能源技术包括:煤炭直接液化、煤炭间接液化、煤焦油联合加氢、煤焦油与燃料油组合、煤焦油乳化、煤水浆和油煤水浆等。重点简述国内外煤炭液化技术发展概况和典型工艺,分析对比2种液化优缺点以及在我国的研发进展和未来发展趋势,并对煤基液态能源技术发展提出若干建议。更多还原

【Abstract】 China’s main source of energy is coal,and there is a conflict existing between the demand and the supply of petroleum and relevant products.To transform coal to liquid to partially replace petroleum,and build the system of coal-based liquid energy source is an important developing direction in China.The coal liquefaction technologies includes the followings:direct coal liquefaction,indirect coal liquefaction,united hydrocraking for coal tar oil,combined fuel of coal tar oil and fuel oil,emulsive fuel,coal-water slurry,oil-coal-water slurry and coal tar pitch fuel,etc.The general situation of technological development and typical processes of coal liquefaction are emphatically discussed in this paper.And a technical analysis and comparison between the two kinds of liquefaction processes are made,and their advantages and disadvantages,the research advances and developing trend in China pointed out.Some advice about developing coal-based liquid energy source is also given.更多还原
