Combined dehydrogenation and disproportionation

Claim 1

A HYDROCARBON CONVERSION PROCESS WHICH COMPRISES: PASSING A HYDROCARBON FEED COMPRISING A REACTANT SELECTED FROM THE GROUP CONSISTING OF ACYCLIC PARAFFINS AND ACYCLIC OLEFINS HAVING 3-6 CARABON ATOMS PER MOLECULE INTO A ZONE CONTAINING A COMBINED DEHYDROGENATION-DISPROPORTIONATION CATALYST COMPRISING A MIXTURE OF BETWEEN 10 98 VOLUME PERCENT OF A DEHYDROGENATION CATALYST ACTIVE FOR HYDROCARBON DEHYDROGENATION AND FORMED OF ALUMINA PROMOTED WITH A MATERIAL SELECTED FROM THE GROUP CONSISTING OF PLATINUM, IRON, POTASSIUM, SODIUM, CHROMIUM, URANIUM, VANADIUM, BERYLLIUM, MAGNESIUM, COPPER, CALCIUM, AND THORIUM AND COMPOUNDS THEREOF AND BETWEEN 2 AND 90 VOLUME PERCENT OF A DISPROPORTIONATION CATALYST ACTIVE FOR OLEFIN DISPROPORTIONATION AND FORMED OF A BASE SELECTED FROM THE GROUP CONSISTING OF SILICA AND SILICA-ALUMINA PROMOTED WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF TUNGSTEN OXIDE AND MOLYBDENUM OXIDE, SAID DEHYDROGENATION COMPONENT BEING EFFECTIVE TO PROMOTE DEHYDROGENATION UNDER CONDITIONS FOR WHICH SAID DISPROPORTIONATION COMPONENT IS EFFECTIVE TO PROMOTE DISPROPORTIONATION; AND MAINTAINING CONDITIONS, INCLUDING CONDITIONS OF TEMPERATURE AND PRESSURE, IN SAID ZONE TO PROMOTE DEHYDROGENATION AND DISPROPORTIONATION.
