Abstract

Hydrocarbon distillates, boiling above 150 DEG C. and containing at least two types of hydro carbons selected from aromatics, naphthenes and paraffins, are redistilled at a subatmospheric pressure below the original distillation pressure such that aromatics distil at relatively lower temperatures than naphthenes and naphthenes lower than parrafins. The redistillation pressure is preferably less than 1/10 of the original pressure and below 100 mm. Hg. The boiling range of the fraction treated is preferably of the order of the boiling point difference anticipated to occur between the various components due to the change in pressure. If desired naphthenes may be dehydrogenated to aromatics and after separation rehydrogenated. Lubricating oils may be separated into fractions having different characteristics which may then be reblended to obtain oils of desired properties, gas oils may be treated to obtain products of higher gravity and lower pour point, cloud point and wax content and waxes may be de-oiled.
