<p>An improved process for sweetening of sour hydrocarbons in a fixed bed treating process wherein the hydrocarbons, containing mercaptans, contact a phthalocyanine catalyst on charcoal in the presence of a basic medium and oxygen. The improvement is use of a quaternary ammonium compound as the basic medium, instead of the aqueous sodium hydroxide solution customarily used. A process for recovery of quaternary ammonium in a compound and its reuse in the process is also disclosed.</p> |
