ABSTRACT:
This invention relates to a process for sweetening a sour hydrocarbon fraction. The process involves two steps. In one step the mercaptans in the sour hydrocarbon fraction are reacted with hydrogen in the presence of a selective hydrogenolysis catalyst to selectively hydrogenolyse the tertiary mercaptans. In another step, the mercaptans are oxidized by reacting them with an oxidizing agent in the presence of oxidation catalyst and a basic component. The selective hydrogenolysis step and the oxidation step may be carried out in any order, i.e., either hydrogenolysis first followed by oxidation or vice versa.
