Document Type and Number:
Japanese Patent JP2006509090
Kind Code:
A
Abstract:
Process to prepare a lubricant having a dynamic viscosity at -35° C. of below 5000 cP by performing the following steps: a) contacting a feed containing more than 50 wt % wax in the presence of hydrogen with a catalyst comprising a Group VIII metal component supported on a refractory oxide carrier, and b) contacting the effluent of step (a) with a catalyst composition comprising a noble Group VIII metal, a binder and zeolite crystallites of the MTW type to obtain a product having a lower pour point than the effluent of step (b) and having a viscosity index greater than 120, and (c) adding a pour point depressant additive to the base oil as obtained in step (b).
