Abstract:
The present invention relates to a Fischer-Tropsch derived residual base oil having a kinematic viscosity at 100° C. according to ASTM D445 in the range of from 15 to 35 mm 2 /s, an average number of carbon atoms per molecule Fischer-Tropsch derived residual base oil according to  13 C-NMR in a range of from 25 to 50.

Claim (Index 9):
A process for preparing a Fischer-Tropsch derived residual base oil according to  claim 1 , wherein the process comprises the steps of:\n (a) providing a hydrocarbon feed which is derived from a Fischer-Tropsch process; (b) subjecting the hydrocarbon feed of step (a) to a hydrocracking/hydroisomerisation step to obtain an at least partially isomerised product; (c) separating at least part of the at least partially isomerised product as obtained in step (b) into one or more lower boiling fractions and a hydrowax residue fraction; (d) catalytic dewaxing of the hydrowax residue fraction of step (c) to obtain a highly isomerised product; (e) separating the highly isomerised product of step (d) into one or more light fractions and an isomerised residual fraction; (f) mixing the isomerised residual fraction of step (e) with a diluent to obtain a diluted isomerised residual fraction; (g) cooling the diluted isomerised residual fraction of step (f) to a temperature between 0\u00b0 C. and \u221260\u00b0 C.; (i) subjecting the mixture of step (g) to a centrifuging step at a temperature between 0\u00b0 C. and \u221260\u00b0 C. to isolate the wax from the diluted isomerised residual fraction; and (j) separating the diluent from the diluted isomerised residual fraction to obtain a Fischer-Tropsch derived residual base oil.
