摘　　要：使用实沸点蒸馏仪对进口俄罗斯原油进行切割,分析所得馏分,并与已知性质的陕西榆林地区原油作对比,得出进口俄罗斯原油综合评价数据。结果表明:与榆林原油相比,进口俄罗斯原油的轻油馏分收率较高,按关键馏分分类属于中间基原油;15~175℃馏分精制后是高品质的乙烯裂解原料,65~175℃馏分可作催化重整原料,140~240℃馏分可生产3号喷气燃料;175~370℃馏分可生产-20号车用柴油,240~360℃馏分可生产-10号车用柴油,360~500℃馏分经脱蜡、精制后,可生产对黏度指数要求不高的润滑油基础油原料,360~540℃馏分是一般的催化裂化原料;>360℃重油馏分属于二类渣油,可部分掺入蜡油中用作催化裂化原料,>540℃渣油馏分属于三类渣油,可用作延迟焦化原料。The imported Russian crude oil was cut by using a true boiling point distiller,and the resulting fractions were analyzed and compared with crude oil from Yulin of Shaanxi Province with known properties to obtain comprehensive evaluation data for the imported Russian crude oil.The results showed that compared with Yulin crude oil,the light oil fraction of imported Russian crude oil had a higher yield and belonged to the intermediate base crude oil according to the key fraction classification.The 15-175℃fraction was a high-quality ethylene cracking feedstock after refining.The 65-175℃fraction could be used as a catalytic reforming feedstock,and the 140-240℃fraction could produce No.3 jet fuel.The 175-370℃fraction could produce-20#motor diesel,the 240-360℃fraction could produce-10#motor diesel,the 360-500℃fraction could produce lubricating oil base oil raw materials with low viscosity index requirements after dewaxing and refining,and the 360-540℃fraction was a general catalytic cracking feedstock.The heavy oil fraction above 360℃belonged to the second type of residual oil,which could be partially blended into wax oil as catalytic cracking feedstock,and the residual oil fraction above 540℃belonged to the third type of residual oil,which could be used as delayed coking feedstock.
