Abstract

Naphthenic type lubricating oils are obtained by subjecting a mixed base lubricating oil distillate fraction to a solvent extraction and dewaxing treatment, the solvent extraction including the steps of extracting with an aromatic-selective solvent, for example, phenol, furfural, liquid SO2, nitrobenzene, and nitroparaffins, in a first stage to obtain a first extract phase, which extract phase is then separated into a second extract phase and a second raffinate phase, from which raffinate phase most of the paraffinic and aromatic compounds have been excluded, and hydrogenating the dewaxed second raffinate in the presence of a catalyst. The dewaxing step may either precede or preferably follow the solvent extraction. The separation of the first extract phase may be effected by at least one of the steps of cooling and injection of anti-solvent, for example water, if desired with concomitant extraction with an aromatic-selective solvent. The dewaxing may be effected by means of a solvent, e.g. MEK-toluene, or by urea adduction. The hydrogenation is preferably effected at 1000-3500 p.s.i.g., 600-750 DEG F., WHSV 0.25-3.0. Any conventional catalyst may be used, the preferred one being cobalt molybdate or alumina. The product preferably has a specific dispersion of 105-140.
