Production of lubricating oil from petroleum wax

Hydrocarbon oils of very high viscosity index, low bromine number and low Couradson carbon value are made by contacting a chlorinated petroleum wax consisting predominantly of monochlorinated wax molecules with a silica-alumina catalyst at above 550 DEG F., but below the temperature at which appreciable cracking occurs and preferably in the range 575-725 DEG F. for a time sufficient to remove substantially all of the chlorine from the chlorinated wax as hydrogen chloride and to produce a substantially saturated oil. "A substantially saturated oil" is one in which the molar unsaturation does not exceed 20 per cent. The chlorinated wax may be made by chlorination to produce a wax of less than 16 per cent chlorine content, preferably 6-12 per cent, or by adsorption fractionation of a chlorinated wax using e.g. silica gel, silica-alumina gel or alumina gel. The wax for chlorination may be slack wax, crude scale wax or a highly refined wax. Waxes of molecular weight above about 350 lead to higher ...
