Abstract
Ligand exchange chromatography is reported as an effective technique for the separation of sulfur compounds from hydrocarbon molecules in a petroleum fraction. Palladium (II) chloride anhydrous, ferric chloride 6‐hydrate, copper (II) sulfate 5‐hydrate, silver nitrate, and tin (II) chloride 2‐hydrate were studied for their effectiveness to separate sulfur compounds present in a Kuwaiti diesel fraction. Tin, silver, and palladium salts were found to be more effective than iron and copper salts for the separation of sulfur compounds from aromatic hydrocarbon molecules present in the fraction by these studies.
