    Abstract: Lube oils of improved viscosity index are prepared by hydrocracking a heavy oil charge stock, separating the lube oil portion of the product into a light cut and a heavy cut, extracting aromatics from the heavy cut, combining the extracted aromatics with the light cut and hydrogenating the mixture. The products may be used separately or the hydrogenated mixture may be combined with the extracted heavy cut.

    Abstract translation: 改进的粘度指数的润滑油是通过加氢裂化重油电荷原料制备的,将产品的润滑油部分分成轻馏分和重馏分,从重馏分中萃取芳烃,将提取的芳族化合物与轻馏分和氢化 混合物。 产物可以单独使用,也可以将氢化混合物与提取的重馏分混合。
