Abstract:
A method for producing a lube basestock from a feed containing 50 wt % or more of wax comprising:(a) hydrotreating the feed under hydrotreating conditions so as to reduce the sulfur and nitrogen content thereof; (b) hydroisomerizing the hydrotreated feed under hydroisomerization conditions to reduce the wax content in the feed to less than about 40 wt %; (c) separating the hydroisomerizated feed of step (b) to obtain a lube fraction boiling above about 340Â° C.; (d) processing the lube fraction of step (c) under hydrocatalytic dewaxing conditions with a catalyst comprising at least one active metal hydrogenation component on a dewaxing catalyst and at least one active metal hydrogenation component on an amorphous hydroisomerization catalyst.
