摘要： Lubricating base oils having a high viscosity index, preferably at least 135, are manufactured by catalytic hydroisomerization of a hydrocarbonaceous feedstock, derived from a waxy crude oil, which feedstock has not been treated to remove a lubricating base oil fraction and which feedstock contains at least 30% by weight wax and has at least 80% by weight boiling above 300.degree. C. and at most 30% by weight boiling above 540.degree. C.

摘要： Process for the manufacture of lubricating base oils from nitrogen-containing distillate and/or deasphalted oils by catalytic hydrotreatment followed by a dewaxing treatment, which comprises subjecting nitrogen-containing distillates and/or deasphalted oils to solvent extraction and subjecting the raffinate and/or the extract produced to a further treatment to obtain a low-nitrogen fraction and a high-nitrogen fraction and subjecting the low-nitrogen fraction from the extract and/or the high-nitrogen fraction from the raffinate to catalytic hydrotreatment.
