Abstract:
Process to prepare a base oil having a viscosity index of between 80 and 140 starting from a distillate or a de-asphalted oil by (a) contacting the feedstock in the presence of hydrogen with a sulphided hydrodesulphurization catalyst comprising nickel and tungsten on an acid amorphous silica-alumina carrier and (b) performing a pour point reducing step on the effluent of step (a) to obtain the base oil.
