Abstract
Hydrocarbon lubricants having a high viscosity index (V.I.) and low pour point are produced by hydroisomerizing, over zeolite beta, a waxy lube feed such as a waxy vacuum gas oil whose aromatic components are removed by extraction, e.g. with furfural. The zeolite beta catalyst comprises noble metal, e.g., Pt, and a low acidity zeolite beta, e.g., framework boron-containing zeolite beta.
