METHOD OF REFINING PETROLEUM AND REFINING APPRATUS

WIPO Patent Application WO/2003/078549

A1

A method of refining raw oil. This method involves the distillation&sol separation step 1 in which the raw oil is separated into a distilled oil M1 and a residual oil M2 by distillation, and the hydrogenation&sol refining step 3 in which the obtained distilled oil M1 and a light oil obtained from the residual oil M2 are hydrogenated and refined in the presence of hydrogen and catalysts. In the hydrogenation&sol refining step 3, the light oil (deasphaltene oil M3) is hydrogenated by passing through a first catalyst layer (a demetallizing catalyst layer 12) and a mixture of the thus hydrogenated light oil (deasphaltene oil M3) with the distilled oil M1 is hydrogenated by passing through a latter catalyst layer (a desulfurizing catalyst layer 13).

JP2966985	[Title of the Invention] A method for catalytic hydrogenation of heavy hydrocarbon oil.
