Abstract
Process for catalytic dewaxing-hydrotreating of hydrocarbon feed materials comprising contacting the feed with hydrogen under catalytic dewaxing-hydrotreating conditions in the presence of a catalyst comprising a shape selective zeolitic cracking component and a hydrogenating component of improved thermal stability comprising a chromium component, at least one other Group VIB metal component and at least one Group VIII metal component. According to a specific aspect of the invention, the catalytic dewaxing-hydrotreating process is employed to convert hydrocarbon feeds of either high or low quality to lube oil base stocks of high viscosity index, low pour point and good stability in a single step.
