摘要： Process to prepare a lubricating base oil starting from a lubricating base oil which is obtained by first removing part of the aromatic compounds from a petroleum fraction boiling in the lubricating oil range by solvent extraction and subsequently dewaxing the solvent extracted product, wherein the following steps are performed, (a) contacting the lubricating base oil with a suitable sulphided hydrotreating catalyst in a first hydrotreating step; (b) separating the effluent of step (a) into a gaseous fraction and a liquid fraction; (c) contacting the liquid fraction of step (b) with a catalyst comprising a noble metal component supported on an amorphous refractory oxide carrier in the presence of hydrogen in a second hydrotreating step; and (d) recovering the lubricating base oil.
