    Abstract: HYDROCARBONS ARE CONVERTED BY CONTACTING THEM AND HYDROGEN, AT HYDROCARBON CONVERSION CONDITION, WITH A CATALYTIC COMPOSITE COMPRISING A COMBINATION OF A PLATINUM GROUP COMPONENT, A RHENIUM COMPONENT, A GROUP VI TRANSITION METAL COMPONENT AND A HALOGEN COMPONENT WITH AN ALUMINA CARRIER MATERIAL IN AMOUNTS SUFFICIENT TO RESULT IN THE COMPOSITE CONTAINING, ON AN ELEMENTAL BASIS, ABOUT 0.05 TO ABOUT 1 WT. PERCENT OF THE PLATINUM GROUP METAL ABOUT 0.05 TO ABOUT 1 WT. PERCENT RHENIUM, ABOUT 0.01 TO ABOUT 1 WT. PERCENT OF THE GROUP VI TRANSITION METAL COMPONENT AND ABOUT 0.1 TO ABOUT 1.5 WT. PERCENT OF HALOGEN. A SPECIFIC EXAMPLE OF THE DISCLOSED PROCESS INVOLVES THE CATALYTIC REFORMING OF A GASOLINE FRACTION WITH THIS CATALYTIC COMPOSITIE.

    Abstract: A SULFUROUS CHARGE STOCK, CONTAINING NITROGENOUS COMPOUNDS AND AROMATIC HYDROCARBONS, IS CONVERTED INTO LOWER-BOILING HYDROCARBON PRODUCTS OF PREDETERMINED END BOILING POINTS. THE CHARGE STOCK, IN ADMIXTURE WITH A PREVIOUSLY HYDROCRACKED, SUBSTANTIALLY DESULFURIZED STREAM, IS SUBJECTED TO A CLEAN-UP OPERATION AT RELATIVELY LOW OPERATING SEVERITIES FOR THE REMOVAL OF NITROGENOUS COMPOUNDS WITHOUT INCURRING THE FORMATION OF APPRECIABLE QUANTITIES OF POLYNUCLEAR AROMATICS. FOLLOWING SEPARATION, A PORTION OF THE SUBSTANTIALLY NITROGEN-FREE PRODUCT IS THEN SUBJECTED TO HYDROCRACKING WITHOUT INCURRING RAPID CATALYST DEACTIVATION NORMALLY RESULTING FROM THE PRESENCE OF CONDENSED RING, POLYNUCLEAR AROMATICS.

    Abstract: CONCERNS AN IMPROVEMENT IN A CONTINUOUS PROCESS FOR THE CATALYTIC REFORMING OF A GASOLINE FRACTION TO PRODUCE A HIGH OCTANE REFORMATE STREAM. CATALYST UTILIZED COMPRISES A PLATINUM GROUP METALLIC COMPONENT, A RHENIUM COMPONENT, A HALOGEN COMPONENT, AND A SULFUR COMPONENT, ALL OF WHICH ARE COMPOSITED WITH AN ALUMINA CARRIER MATERIAL. IMPROVED PROCESS INVOLVES CONTINUOUSLY CONTACTING THE GASOLINE FRACTION, HYDROGEN, AND ABOUT 50 TO 3000 WT. P.P.M. OF EQUIVALENT SULFUR, BASED ON THE HYDROCARBON FRACTION, WITH THE CATALYST AT REFORMING CONDITIONS-PARTICULARLY, A PRESSURE OF ABOUT 100 TO 350 P.S.I.G. POINTS OF IMPROVEMENT INVOLVES: OVERALL STABILITY, CATALYST LIFE BEFORE REGENERATION, AND RATE OF DEPOSITION OF CARBONACEOUS DEPOSITS ON THE CATALYST.
