摘要
煤直接液化技术作为石油替代的重要途径之一,长期以来一直受到人们的关注。本文结合世界上第一套煤直接液化工业示范工程的实践,划分和描述了煤直接液化技术的不同发展历程和煤直接液化技术的进展,对煤液化最新技术的开发过程、技术特点、试验情况和关键技术研究等进行了阐述,并指出了煤直接液化技术将在煤液化特性、分级转化、反应器大型化、工艺优化、主副产品结构优化等方向作为未来的研究开发方向。
The direct coal liquefaction technology, as one of the important routes to substitute oil, has attracted people’s attention and concern for a long time. Combining the practice of the world first direct coal liquefaction demonstration project, the paper describes the different developing courses and the latest progress of direct coal liquefaction technologies and elaborates the development process of new coal liquefaction technologies, technical characteristics, experimental work and research of core technologies. The paper also points out the orientation of future research and development of direct coal liquefaction technologies in the aspects of graded conversion based on coal characteristics, scaling up of reactor, process optimization, main product and by-product mix optimization, etc.
