Abstract

A process for the production of a refined mineral oil comprises the steps of hydrogenating a light distillate oil having a boiling-point of from 120 DEG to 310 DEG C. under a pressure of 6 mm. of mercury under the following conditions:- .Temperature ( DEG C.).280 -370 .Pressure (bars).20 -150 .Spacial velocity.0.3- 3.5 .Volumes of hydrogen (re. .duced to N.T.P.) per. .volume of oil.100 -500 deriving a raffinate of reduced aromatic hydrocarbon content by solvent extraction of a light distillate oil having a boiling point of from 120 DEG to 310 DEG C. under a pressure of 6 mm. of mercury, hydrogenating the raffinate under less severe conditions than the light distillate oil, and combining the hydrogenated light distillate oil with the hydrogenated raffinate. The solvent may be phenol, furfural, sulphur dioxide, or propane-cresol; the hydrogenation catalyst may be cobalt molybdate on alumina. The product is oxidation-resistant, of low dielectric loss and suitable for electrical purposes.
