Contaminant removal from hydrocarbon streams with carbenium pseudo ionic liquids

摘要

Processes for removing sulfur and nitrogen contaminants from hydrocarbon streams are described. The processes include contacting the hydrocarbon stream comprising the contaminant with lean carbenium pseudo ionic liquid or a combination of carbenium pseudo ionic liquid and ionic liquid to produce a mixture comprising the hydrocarbon and rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid comprising the contaminant. The mixture is separated to produce a hydrocarbon effluent and a rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid effluent comprising the rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid comprising the contaminant.

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 carbenium pseudo ionic liquid to produce a mixture comprising the hydrocarbon and a rich carbenium pseudo ionic liquid comprising the contaminant, the carbenium pseudo ionic liquid comprising an organohalide and a metal halide with the proviso that the organohalide is not a butyl halide or acyl halide; and separating the mixture to produce a hydrocarbon effluent and a rich carbenium pseudo ionic liquid effluent comprising the rich carbenium pseudo ionic liquid comprising the contaminant.
