PROCESS FOR REGENERATING IONIC LIQUIDS BY ADDING LIGHT HYDROCARBON STREAM

摘要

A process for removing at least one impurity from a hydrocarbon feed such as vacuum gas oil in which the process includes the steps of contacting the feed with a hydrocarbon-immiscible phosphonium ionic liquid to produce a hydrocarbon and hydrocarbon-immiscible phosphonium ionic liquid mixture, and separating the mixture to produce a hydrocarbon effluent having a reduced impurity content relative to the hydrocarbon feed.
