    • The invention provides a method of producing oil-based components, comprising the steps of: providing VGO and wax; combining the VGO as a major component and the wax as a minor component to provide a feedstock; subjecting the feedstock to a hydrocracking step to provide a first effluent; fractionating the first effluent to provide at least a bottom fraction and a middle distillate fraction; recovering the bottom fraction and the middle distillate fraction. The invention further provides a method for improving the viscosity index of base oil, comprising the steps of: providing VGO and wax; combining the VGO as a major component and the wax as a minor component to provide a feedstock; subjecting the feedstock to a hydrocracking step to provide a first effluent; fractionating the first effluent to provide at least a bottom fraction and a middle distillate fraction; subjecting the bottom fraction to a dewaxing step to provide a second effluent; fractionating the second effluent to provide at least a middle distillate and base oil; recovering the middle distillate and the base oil.
    • 本发明提供一种生产油基成分的方法,包括以下步骤:提供VGO和蜡; 将VGO作为主要组分并且蜡作为次要组分组合以提供原料; 使原料进行加氢裂化步骤以提供第一流出物; 分馏第一流出物以提供至少一个底部馏分和一个中间馏分馏分; 回收塔底馏分和中间馏分。 本发明还提供一种提高基油粘度指数的方法,包括以下步骤:提供VGO和蜡; 将VGO作为主要组分并且蜡作为次要组分组合以提供原料; 使原料进行加氢裂化步骤以提供第一流出物; 分馏第一流出物以提供至少一个底部馏分和一个中间馏分馏分; 使底部馏分进行脱蜡步骤以提供第二流出物; 分馏第二流出物以提供至少一种中间馏分和基础油; 回收中间馏分油和基础油。
