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。
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.
