DENITROGENATION OF HYDROCARBONS BY LIQUID-LIQUID EXTRACTION USING IONIC LIQUIDS

This invention is related a process for reducing nitrogen-containing compounds from hydrocarbon mixtures using ionic liquids of general formula C + A-, where C + represents a cation of organic or inorganic type, specifically of the type imidazolium, pyridinium or ammonium salts, while the anion A- a...

Beschreibung
Zusammenfassung:	This invention is related a process for reducing nitrogen-containing compounds from hydrocarbon mixtures using ionic liquids of general formula C + A-, where C + represents a cation of organic or inorganic type, specifically of the type imidazolium, pyridinium or ammonium salts, while the anion A- are derivatives which are halides, salts of iron (III), aluminum salts (III), acetate and benzoate, though not exclusively. These agents act as ionic liquid extractants of nitrogenated compounds contained in hydrocarbon streams through a process of liquid-liquid extraction thereby can be reduced by more than 60% the content of these contaminants in hydrocarbon streams.
