ABSTRACT:
An improved process is described for removing mercaptan sulfur from sour hydrocarbon distillate streams comprising of treating a sour hydrocarbon distillate stream in two oxidation zones within a reaction vessel. The first treatment occurs in the presence of a fiber bundle and the subsequent treatment over a bed of supported oxidation catalyst. The improvement comprises continuously keeping the bed in contact with an aqueous alkali metal hydroxide to maintain the catalyst in a caustic-wetted state, without interrupting the operation of the process.
