Abstract (en)
[origin: WO2013150114A2] The present invention provides a process to prepare a residual base oil, which process at least comprises the following steps: (a) providing a mineral bright stock waxy raffinate; (b) combining the mineral bright stock waxy raffinate provided in step (a) with a catalytically dewaxed residual Fischer-Tropsch derived base oil to obtain a mixture; and (c) solvent dewaxing the mixture obtained in (b) to obtain a residual base oil, wherein the weight ratio of the mineral bright stock waxy raffinate to the catalytically dewaxed residual Fischer-Trospch derived base oil in step (b) is in the range of from 75:25 to 35:65. In another aspect the present invention provides a residual base oil obtainable by the process.
