摘 要:为弄清加氢生产高档润滑油基础油(简称基础油)时原料变化的影响,探讨决定基础油黏温性能的关键因素,分析了减压馏分油(VGO)、加氢裂化尾油、基础油等油品的物理性质和化学组成。结果表明,VGO的黏度指数及其中链烷烃、一环环烷烃和烷基苯的质量分数之和与以其为原料生产所得基础油的黏度指数有较好的正相关关系。考察基础油黏度指数与化学组成,发现基础油的黏度指数主要受其链烷烃和一环环烷烃的含量以及碳数分布、异构化程度的影响。To understand the effect of feedstock change on hydrotreated lube base oil,the physicochemical properties of vacuum gas oil(VGO),hydrocracking tail oil and hydrotreated base oil were analyzed to investigate the key factors that determine the viscosity-temperature performance of base oil.The results showed that the viscosity index(Ⅵ)and the sum of the mass fraction of paraffins,monocyclic naphthene and alkyl benzenes of VGO are positively correlated with the Ⅵ of base oil produced from VGO.The relations between Ⅵ and chemical compositions of the base oil indicated that the Ⅵ of the base oil was mainly affected by the content of paraffins and monocyclic naphthenes,the distribution of carbon number and the degree of isomerization.
