The M-28 Catalyst was developed by SJEP and China University of Petroleum (east China). It is a special equipped solid catalyst, which uses wooden activated carbon as the carrier, carrying metal compound. This catalyst is specially developed to match the new technology of gasoline mercaptan conversion, with long life span, high refinery capacity. The procedure realizes cleaner production with no waste alkaliliquor disposal during the application. It is applied for gasoline sweetening and also applied for the production of clean oil such like naphtha and so on.
