Abstract: 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.

Abstract: A process is provided for removing a heavy polynuclear aromatic (HPNA) compound from a hydrocarbon oil. The process includes contacting the hydrocarbon oil containing the HPNA compound with a lean hydrocarbon-immiscible liquid stream to produce a mixture comprising the hydrocarbon oil and a rich hydrocarbon-immiscible liquid containing the HPNA compound; and separating the mixture to produce a hydrocarbon oil effluent having a reduced level of the HPNA compound and a hydrocarbon-immiscible liquid effluent containing the HPNA compound. The hydrocarbon-immiscible liquid can be a halometallate ionic liquid, a liquid coordination complex, or a combination thereof.

Abstract: We provide a process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers in a reactor, by removing at least 57 wt % of the conjunct polymers originally present in the used acidic ionic liquid catalyst in a separate regeneration reactor, so as to increase the activity of the catalyst. We also provide a regenerated used acidic ionic liquid catalyst having increased activity.
