A PROCESS AND CATALYST FOR THE PARTIAL OXIDATION OF PARAFFINIC HYDROCARBONS, SUCH AS ETHANE, PROPANE, NAPHTHA, AND NATURAL GAS CONDENSATES, TO OLEFINS, SUCH AS ETHYLENE AND PROPYLENE. THE PROCESS INVOLVES CONTACTING A PARAFFINIC HYDROCARBON WITH OXYGEN IN THE PRESENCE OF HYDROGEN AND A CATALYST UNDER AUTOTHERMAL PROCESS CONDITIONS. PREHEATING THE FEED DECREASES OXYGEN CONSUMPTION AND INCREASES THE NET HYDROGEN BALANCE. THE CATALYST COMPRISES A GROUP 8B METAL, PREFERABLY, A PLATINUM GROUP METAL, AND AT LEAST ONE PROMOTER SELECTED FROM GROUPS 1B,6B,3A,4A, AND 5A, OPTIONALLY SUPPORTED ON A CATALITIC SUPPORT, SUCH AS MAGNESIA OR ALUMINA. IN PREFERRED EMBODIMENTS, THE SUPPORT IS PETREATED WITH A SUPPORT MODIFIER SELECTED FROM GROUPS 1A,2A,3B,4B,5B,6B,1B,3A,4A,5A, THE RARE EARTH LANTHANIDES, AND THE ACTINIDES. A MODIFIED FLUIDIZED BED REACTOR IS DISCLOSED FOR THE PROCESS. |
