ABSTRACT:
A process is disclosed for oxidizing difficultly oxidizable mercaptans contained in a hydrocarbon fraction which comprises adding a hydrocarbon soluble alkali metal compound, capable of forming the alkali metal mercaptides of the difficultly oxidized mercaptans, to the hydrocarbon fraction; and contacting the resulting hydrocarbon fraction containing the hydrocarbon soluble alkali metal compound with a metal chelate catalyst disposed on an adsorptive support in the presence of a hydrated oxygen-containing gas and in the absence of a separate water phase.
