Process for removing sulfur compounds from vacuum gas oil

摘要

pA process for removing a sulfur compound from a low nitrogen content vacuum gas oil feed includes contacting the low nitrogen content vacuum gas oil feed comprising the sulfur compound with a VGO immiscible phosphonium ionic liquid to produce a vacuum gas oil and VGO immiscible phosphonium ionic liquid mixture and separating the mixture to produce a vacuum gas oil effluent having a reduced sulfur compound content relative to the vacuum gas oil feed. It was found that the amount of the sulfur compound being removed was significantly improved by treating a low nitrogen content vacuum gas oil. The low nitrogen content and especially a low level of polar nitrogen compounds increases the amount of sulfur compounds that can be removed./p
