Abstract: Lube oils of improved viscosity index are produced by subjecting a crude lubricating oil to hydrocracking, selectively fractionating the hydrocracked product to yield a product having the desired flash point and viscosity and recycling the fractionator bottoms to the hydrocracking zone.
Abstract translation: 改善粘度指数的润滑油是通过对粗润滑油进行加氢裂化，选择性分馏加氢裂化产物以产生具有所需闪点和粘度的产物，并将分馏塔底部再循环至加氢裂化区来生产的。
