煤液化技术研究现状及其发展趋势

能源安全和环境保护是我国21世纪应引起高度重视的问题,煤炭既是能源的主要提供者,也是大气污染的主要污染源,其高效洁净利用不容忽视,煤炭液化技术是解决此矛盾的有效途径之一。对煤液化的发展历程、开发和应用现状以及发展趋势和产业化前景进行了概括,详细介绍了煤直接液化、间接液化和煤与废塑料共液化技术的特性、影响因素及其关键问题,并提出了煤液化技术在我国今后发展的一些看法和建议。

Present status and developing trends of coal liquefaction techniques

Energy safety and environmental protection are the problems which China ought to pay great attention to.Coal is the major energy source,and also the major pollution source discharged to the air,efficient and clean use of it allows of no negligence.The technology of coal liquefaction is one of the main ways to resolve the problems.The development course,research status,exploitation and their application and the outlook of industrialization of coal liquefaction techniques are briefly reviewed in this paper.The characteristics,influencing factors and the key problems of direct,indirect coal liquefaction and(co-liquefaction) of coal and waste plastic are discussed.Some suggestions and viewpoints are given for the future coal liquefaction research and development in China.
