HYDROCARBONS ARE CONVERTED BY CONTACTING THEM, AT HYDROCARBON CONVERSION CONDITIONS, WITH A CATALYTIC COMPOSITE, COMPRISING A PLATINUM GROUP COMPONENT AND A GROUP IV-A METALLIC COMPONENT COMBINED WITH A CARRIER MATERIAL CONTAINING ALUMINA AND FINELY DIVIDED, ZEOLITIC CRYSTALLINE ALUMINOSILICATE. A SPECIFIC EXAMPLE OF THE HYDROCARBON CONVERSION PROCESSES DISCLOSED HEREIN IS A PROCESS FOR PRODUCING LPG AND A HIGH OCTANE REFORMATE, WHICH COMPRISES CONTACTING A HYDROCARBON CHARGE STOCK AND HYDROGEN, AT LPG PRODUCTION CONDITIONS, WITH A CATALYTIC COMPOSITE CONTAINING 0.01 TO 2 WT. PERCENT PLATINUM, 0.1 TO 3.5 WT. PERCENT HALOGEN AND 0.01 TO 5 WT. PERCENT GERMANIUM COMBINED WITH A GAMMA-ALUMINA CARRIER MATERIAL HAVING 0.1 TO 20 WT. PERCENT OF THE HYDROGEN FORM OF MORDENITE UNIFORMLY DISTRIBUTED THERETHROUGH. |
