摘要：
The present invention involves a process for removing one or more polycyclic aromatic hydrocarbon compounds from a vacuum gas oil comprising contacting the vacuum gas oil with a vacuum gas oil-immiscible phosphonium ionic liquid to produce a mixture comprising the vacuum gas oil and the vacuum gas oil-immiscible phosphonium ionic liquid, and separating the mixture to produce a vacuum gas oil effluent and a vacuum gas oil-immiscible phosphonium ionic liquid effluent, the vacuum gas oil-immiscible phosphonium ionic liquid effluent comprising the polycyclic aromatic hydrocarbon compound.
