煤直接液化用溶剂的研究现状

对前人在煤直接液化研究中所使用的溶剂的种类、作用和优缺点进行综述,指出开发新的溶剂,使煤液化在较低温度和压力下完成并获得高的油收率是煤直接液化更容易实现和产业化的关键。 This article for the predecessor the solvent type,the function and the good and bad points uses in the coal direct liquefaction research carries on the summary,pointed out that develops the new solvent,causes the liquefaction of coal completes and obtains high oil receiving rate under the low temperature and the pressure is the coal direct liquefaction is easier to realize with the industrial production key
