1前言长期以来,美、中、俄罗斯(原苏联)、日本和德国等工业发达国家坚持不懈地进行着煤深加工的研究,并且不断获得新的产品。直至目前,在实验室和工业示范装置层面上,全世界已有60多项煤制取液体产品的技术,多为直接液化法。商业性F-T法,即间接液化法,就是南非的SASOL技术。它包括SASOL-Ⅱ流程 1 Introduction For a long time, industrial developed countries such as the United States, China, Russia (former Soviet Union), Japan, and Germany have been tirelessly carrying out research on deep processing of coal, and they have continuously obtained new products. Until now, at the level of laboratory and industrial demonstration plants, there are more than 60 coal-producing technologies for liquid products around the world, mostly direct liquefaction. The commercial F-T method, indirect liquefaction, is South Africa’s SASOL technology. It includes the SASOL-II process
