PRODUCTION OF HIGH QUALITY LUBRICATING BASE OIL
@@High VI lubricating oil is produced in hydrocracker through hydrocracking (HDC) and hydroisome-rization reactions. In order to effectively produce high VI component, such as iso-pafaffins and monocyclic naphtenes, it is important to load suitable HDC catalysts and operate them in the appropriate reaction conditions. Nippon Mitsubishi Oil Corporation (NMOC) and its affiliate company, Nippon Mitsubishi Petroleum Refining Company (NMPRC) reported their original HDC catalysts four years ago in this Japan-China joint se-minar in Beijing［1］. NMOC and NMPRC operate their hydrocracker both in fuel oil production mode and in lubricating oil production mode. In lubricating oil production mode, high VI lubricating oil called VHDC are produced. In this paper, at first, the advantages of high VI lubricating oil are described. And then it is announced that NMOC and NMPRC have developed a new generation of HDC catalyst with higher cracking activity, higher middle distillate selectivity and longer life than the other commercial HDC catalysts. In addition to those properties, the catalyst is able to yield high VI lubricating oil as well.
