Catalyst Innovation for Reducing Olefin Content in MGG Gasoline

In order to reduce the olefin content in gasoline manufactured by the MGG (Maximizing Liquefied Gas and Gasoline) process while retaining the LPG yield, RIPP has developed a novel catalyst consisting of a more pore-opened matrix and the modified Y-zeolite and the ZRP zeolite modified with metal oxides. Test results have revealed that compared with the commercial catalyst RAG under comparable reaction conditions the reaction conversion rate and product distribution provided by the novel catalyst were similar, but the olefin content in gasoline obtained thereof was decreased with the octane rating unchanged along with a slight reduction of olefin content in the LPG fraction. The hydrothermal stability of the novel catalyst was better than the commercial catalyst RAG.
