A PROCESS FOR REFORMING A HYDROCARBON FRACTION SUBSTANTIALLY FREE OR DIMETHYLBUTANES. THE HYDROCARBON IS SEPARATED INTO A FRACTION COMPRISING THE C5-HYDROCARBONS AND THE DIMETHYLBUTANES, A LIGHT FRACTION EXCLUDING DIMETHYL BUTANES, AND A HEAVY FRACTION. THE LIGHT FRACTION IS REFORMED IN THE PRESENCE OF A MONOFUNCTIONAL CATALYST, AND THE HEAVY FRACTION IS REFORMED IN THE PRESENCE OF A BIFUNCTIONAL CATALYST. |
