SWEET OR SOUR SERVICE CATALYTIC DEWAXING IN BLOCK MODE CONFIGURATION

摘要

Sweet and sour lubricant feeds are block and continuous processed to produce lubricant basestocks. Total liquid product yields at a desired pour point are maintained for catalytic dewaxing of both sweet and sour conditions. The desired pour point is achieved for both the sweet and sour feeds by varying the catalytic dewaxing reaction temperature as a function of sulfur content entering the reactor.
