Abstract

Dark-coloured mineral oils poor in aromatics and having a higher boiling range than that of kerosine, such as lubricating oils, insulating oils and transformer oils, are purified by percolation through bauxite at temperatures above 200 DEG C., but below the temperature at which considerable cracking takes place, preferably between 225 DEG and 275 DEG C. The percolation may be carried out at increased or reduced pressure. Preferably, a bauxite of low iron content is used. The size of grain may vary from 0.2 to 1.0 mm. and the bauxite may be placed in a cylindrical vessel of a diameter from 1 to 5 metres resting on a perforated plate to a thickness of 1 to 10 metres. Before use, the bauxite is dried and activated by heating to 500 DEG C. The oil remaining in the bauxite can be recovered by extraction with a solvent and added to a subsequent charge, or percolated separately.
