Abstract:
1. A method for upgrading a hydrocarbon containing mercaptans, comprising: (a) contacting the hydrocarbon under substantially anaerobic conditions with a first phase of a treatment composition containing water, alkali metal hydroxide, cobalt phthalocyanine sulfonate, and alkylphenols and having at least two phases, (b) extracting mercaptan sulfur from the hydrocarbon to the first phase; (c) separating an upgraded hydrocarbon; (d) conducting an oxidizing amount oxygen and the first phase containing mercaptan sulfur to an oxidizing region and oxidizing the mercaptan sulfur to disulfides; (e) separating the disulfides from the first phase; and then (f) conducting the first phase to step (a) for re-use.
