Abstract
A process for the preparation of a lubricating base oil including contacting a hydrocarbon feed with a catalyst in the presence of hydrogen, which catalyst includes a hydrogenation component supported on an amorphous silica-alumina carrier having a macroporosity in the range of from 5% vol to 50% vol. The hydrocarbon feed is most preferably a slack wax or a synthetic wax. The preferred catalyst for use in the process includes a combination of one or more of the metals cobalt, iron, and nickel, and one or more of the metals chromium, molybdenum, and tungsten on an amorphous silica-alumina carrier having a macroporosity in the range of from 5% vol to 50% vol.
