ABSTRACT:
A method is disclosed for reducing the nitrogen content of hydrocarbon liquids. The method comprises contacting the hydrocarbon liquid with a solid metal salt capable of selectively extracting nitrogen-containing compounds from the hydrocarbon liquid to thereby form a nitrogen-rich solid extract. Nitrogen-lean hydrocarbon liquid is then separated from the solid extract. The solid extract is washed with a solvent capable of selectively dissolving non-nitrogen-containing compounds entrained in the solid extract. The solid extract is then treated with a release agent for selectively dissolving nitrogen-containing compounds to thereby recover the metal salt. The presently preferred metal salt is cupric chloride.
