Abstract

See full text

A process for removing heavy polycyclic aromatic contaminants from a hydrocarbon stream using a quinolinium ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a hydrocarbon-immiscible quinolinium ionic liquid to produce a mixture comprising the hydrocarbon and a hydrocarbon-immiscible quinolinium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent having a reduced level of the contaminant and a hydrocarbon-immiscible quinolinium ionic liquid effluent comprising the hydrocarbon-immiscible quinolinium ionic liquid comprising at least the portion of the removed contaminant.
