Abstract: The viscosity index of a hydrocracked lubricating oil stock boiling in the range of about 600*-1100* F. is increased by fractionating the stock into a light fraction boiling from 600* F. to about 750* F. and a bottoms fraction; mildly hydrogenating the light fraction and subsequently reblending the hydrogenated light fraction with the unhydrogenated fraction. Low boiling cracked hydrocarbons may be removed from the reblended lubricating oil to adjust the initial boiling point temperature to a desired value.

Abstract translation: 通过将原料分馏成沸腾至600°F至约750°F的轻馏分和塔底馏分，将沸点在约600°-1100°F范围内的加氢裂化润滑油原料的粘度指数提高。 轻轻地使轻馏分氢化，随后用未氢化的馏分使氢化轻馏分反应。 低沸点裂化烃可以从再润滑的润滑油中除去，以将初始沸点温度调节至所需值。
