More Information
Summary:An FCC process converts a secondary feed comprising a heart of a gasoline product stream with spent catalyst at mild conditions to obtain a surprising increase in the octane number of the resulting gasoline product. More surprisingly, the increase in gasoline stream octane number occurs with very low production of dry gas. Limiting the presence of heavy gasoline components was found to significantly raise the octane number produced by the process.
