Abstract
A process for sweetening a petroleum fraction by catalytic oxidation of mercaptans contained therein in a fixed bed of the supported catalyst, with the oxidation reaction being carried out in the absence of an aqueous phase and in the presence of an oxidizing agent, and the water molecules formed during the oxidation reaction being removed from the catalyst support by washing the latter periodically with a substantial quantity of a polar solvent that is miscible with water.
