Abstract (en)
A sour hydrocarbon fraction is sweetened by treating the sour hydrocarbon fraction containing mercaptans with sufficient unsaturated hydrocarbons in the presence of an acid-type catalyst at non-oxidative reaction conditions selected to convert said mercaptans to thioethers. Acid type catalysts which may be used include polymeric sulfonic acid resins, intercalate compounds, solid acid catalysts and acidic inorganic oxide catalysts.
