Patent

CA 2422813

Sulfur levels in a mercaptan sulfur cotaining hydrocarbon feedstream are decreased by passing the feedstream over a fixed bed catalyst in the presence of a stripping gas under conditions sufficient to decompose at least a portion of the mercaptans to produce olefins, H2S, an off gas, and a haydrocarbon product stream having decreased levels of mercaptan sulfur and to disengage the product stream from the H2S.

L'invention porte sur un procédé de désulfuration d'un flux d'hydrocarbure contenant des mercaptans consistant à le faire passer sur un catalyseur à lit fixe en présence d'un gaz d'épuisement dans des conditions suffisantes pour décomposer au moins une partie des mercaptans et produire des oléfines, du H2S, un gaz de dégagement et un flux d'hydrocarbures à teneur moindre en mercaptans, puis à séparer le flux d'hydrocarbures du H2S.
