煤炭直接液化技术及其发展趋势

The Technology and Development Tendency of Coal Direct Liquefaction

煤炭直接液化技术属于洁净煤技术的一种。文章简要论述了煤炭直接液化技术的化学反应机理和化学反应过程,直接液化对原料煤的要求以及适合煤直接液化的煤种;回顾了液化技术的发展历史,国外煤直接液化技术的发展状况;介绍了我国煤碳直接液化的现状;展望今后煤炭直接液化的发展方向,对有关学者提出的"煤的分级集成利用技术"的概念进行了分析。

Coal direct liquefaction was kind of technology that belong to cleaning coal technology. In the paper, the chemical reaction and the process were introduced; the requirement of raw coal for coal direct liquefaction is also mentioned. Reviewing the histoW of coal direct liquefaction in and out of China, some people put forward the conception of Integrated Coal-hydrogenation, and this should be the tendency of coal chemical industry.
