Abstract

Process for producing lubricating base oils, which process comprises the steps of:
(a) contacting a hydrowax obtained as the bottom fraction of a hydrocracked effluent with a catalyst comprising platinum and/or palladium on a refractory oxide carrier in the presence of hydrogen under such conditions that at least 10% by weight, preferably at least 25% by weight, of the hydrocarbons having a boiling point of 370 °C or higher, which are present in the hydrowax, is converted into hydrocarbons having a lower boiling point, (b) separating the product obtained in step (a) in at least one lighter distillate fraction and a heavy distillate fraction having a VI of 125 or higher, preferably of 135 or higher, and a kinematic viscosity at 100 °C of a least 3.5 centiStokes, and (c) dewaxing the heavy distillate fraction obtained in step (b).
