METHOD OF PRODUCTION OF THE BASE OIL WITH THE HIGH CONTENT OF THE SATURATED HYDROCARBONS Russian patent published in 2006 - IPC C10G65/08 

FIELD: oil-processing industry; methods of production of the base oil with the high content of the saturated hydrocarbons.

SUBSTANCE: the invention is pertaining to the field of oil-processing industry, in particular, to the method of production of the base oil with the high content of the saturated hydrocarbons. The method provides, that the selectively purified base oil raw stock is subjected at the stage of (a) to the contact with the hydrogen-containing gas in the first reaction zone containing of one or more the fixed beds of the catalytic agent containing at least one metal of VI-B group and at least one base metal of VIII group deposited the refractory, oxide carrier. On the stage (b) the stream of the outgoing gas makes the contact with the hydrogen-carrying gas in the second reaction zone containing one or more the fixed beds of the catalytic agent containing the alloy of platinum and palladium and the silica-alumina carrier. At that the base oil raw stock at the stage of (a) moves as a counter current to the up-going stream of the hydrogen-containing gas. The technical result of the invention is the improved quality of the target product.

EFFECT: the invention ensures the improved quality of the target product.
