煤直接液化研究评述

比较了中国与国际基础研究水平的差距,对主要的新老工艺进行了分类和比较,发现成功的液化工艺都符合煤分子结构的特点。高温快速液化是一种基于煤分子结构特殊性的直接液化方案,在理论上提供了实现最高液化效率和最低液化成本的可能性,联产芳香族化合物和燃料油,开辟了一个新的研究方向。 The gap between national and international research level is compared.Fifteen new and old processes are classified and compared,and it is found that successful liquefaction processes all accord with the structural characteristics of coal molecule.Quick liquefaction at high temperature is a direct liquefaction scheme based upon the characteristics of coal molecule,which opens a new research field.In theory,it provides the possibility to achieve the highest liquefaction efficiency and the lowest liquefaction cost,and aromatic compounds and fuel oils could be produced jointly
