Abstract (en)

[origin: EP0776959A2] Process for the preparation of lubricating base oils having a VI of at least 150 from a Fischer-Tropsch wax feed, which process comprises the steps of: (a) contacting the Fischer-Tropsch wax feed with a hydroconversion catalyst under hydroconversion conditions, (b) separating the hydroconverted effluent obtained in step (a) into at least one lighter fraction and a heavy fraction, and (c) dewaxing the heavy fraction to yield the base oil, wherein the Fischer-Tropsch wax feed has a congealing point of at least 50 DEG C and has such boiling range that the difference between the 90 %wt boiling point and the 10 %wt boiling point (T90-T10) is in the range of from 40 to 150 DEG C.
