摘　　要：探讨了煤直接液化溶剂在煤直接液化过程中的重要作用,重点介绍了油浆和油煤共炼产物中的某三种重劣质油(含固重劣质油、脱固重劣质油、加氢重馏分油)作为煤直接液化部分溶剂的研究进展,发现在悬浮床加氢裂化中试装置上,在煤浓度为40%~45%、反应温度465~468℃、压力20~22 MPa、空速0.5 kg/(h·L)、催化剂占总量的1%的工艺条件下,其中一种重劣质油(加氢重馏分油)是煤直接液化比较好的溶剂。Coal direct liquefaction solvent is discussed in the important role of coal direct liquefaction process,analysis the effect of coal direct liquefaction solvent,mainly introduced the FCC slurry and coal oil,refined product of some three kinds of inferior oil in the heavy(including solid weight inferior oil,solid heavy inferior oil,hydrogenated distillate) as the research progress of coal direct liquefaction of some solvents,found on the suspended bed hydrocracking pilot plant,the coal concentration of 40%~45%,reaction temperature 465~465 ℃,20~22 mpa pressure,space velocity of 0.5 kg/(h·L),catalyst accounts for 1% of the total process conditions,It is found that one of the heavy crude oil(hydrogenated heavy distillate oil) is a better solvent for direct liquefaction of coal.
