Patent ID: 7497941

Claim:
A process to prepare two or more lubricating base oil grades and a gas oil comprising: (a) hydrocracking or hydroisomerizing a Fischer-Tropsch product, wherein a weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms in the Fischer-Tropsch product is at least 0.2 and wherein at least 30 wt % of compounds in the Fischer-Tropsch product have at least 30 carbon atoms to produce a hydrocracking or hydroisomerizing product; (b) separating the hydrocracking or hydroisomerizing product of step (a) into one or more gas oil fractions and a base oil precursor fraction; (c) performing a pour point reducing step to the base oil precursor fraction obtained in step (b) to produce an effluent; and, (d) separating the effluent of step (c) into two or more base oil grades.
