Claim:
1. A process for removing a contaminant comprising at least one of sulfur and nitrogen from a hydrocarbon stream comprising: contacting the hydrocarbon stream comprising the contaminant with a lean hydrocarbon-immiscible halometallate ionic liquid and an organohalide or HCl resulting in a mixture comprising the hydrocarbon and a rich hydrocarbon-immiscible halometallate ionic liquid comprising the contaminant wherein the hydrocarbon-immiscible halometallate ionic liquid comprises a haloaluminate ionic liquid, a haloferrate ionic liquid, a halocuprate ionic liquid, a halozincate ionic liquid, or combinations thereof and wherein the aloaluminate in said haloaluminate ionic liquid is selected from the group consisting of Al separating the mixture to produce a hydrocarbon effluent and a rich hydrocarbon-immiscible halometallate ionic liquid effluent comprising the rich hydrocarbon-immiscible halometallate ionic liquid comprising the contaminant.
