摘　　要：对煤直接液化柴油(diesel of direct coal liquefaction,DDCL)和煤间接液化柴油(diesel of indirect coal liquefaction,DICL)的性质进行了分析,通过调和试验考察了二者的相容性、煤液化调和柴油的性质规律及其对润滑性改进剂的感受性;并通过发动机台架试验考察了煤液化调和柴油的动力性、经济性和排放性能.结果表明:DDCL与DICL有很好的相容性;煤液化调和柴油的密度和十六烷值与其中DICL的质量分数呈线性关系,能够实现二者的优势互补;其对润滑性改进剂具有良好的感受性;在国Ⅳ发动机上有很好的动力性,单位质量油耗略有优势,常规排放满足国Ⅳ排放标准,且在NO_x、烟度和PM排放方面有较大优势.The properties of diesel of direct coal liquefaction （DDCL） and diesel of indirect coal liquefaction （DICL） were analyzed, the miscibility of the two types of diesel, the properties of blending diesel and the effect of lubricity additives on the two types of diesel were studied by the blending experiment, and the mobility, economy and emission performance of the blending diesel were investigated by engine bench test. The results show that DDCL is well dissolvable with DICL, and the density and the cetane number of the blending diesel are both linearly related to the mass fraction of DICL. It indicates that the two types of diesel have complement advantages with each other very well. The blending diesel has good sensibility to the lubricant. It is found that the blending diesel of coal liquefaction has good dynamic performance, less fuel consumption per unit mass and less pollutant emissions on China IV engine. The regulated emissions of the blending diesel fuel meet China IV emission standard. It has great advantage in the emissions of NOx, smoke intensity and particulate matter.
