    Abstract: A novel bimetallic catalyst especially useful for the low temperature reduction of oxysulfur compounds with hydrogen, is disclosed. The bimetallic catalyst is a combination of catalytically effective amounts of molybdenum sulfide and of cobalt sulfide with a porous carrier material. It is prepared by impregnating the carrier material with a first metallic component drying and sulfiding to form a sulfided monometallic composite, purging free sulfide from contact with same, impregnating the resulting composite with the second metallic component to form a bimetallic composite, and thereafter, drying and sulfiding the resulting bimetallic composite to produce the bimetallic catalyst. The resulting bimetallic catalyst is especially useful in a method for reducing an inorganic, water-soluble oxysulfur compound wherein an aqueous solution of the oxysulfur compound and hydrogen are contacted with the bimetallic catalyst at reduction conditions.

    Abstract: ALREADY-TO-USE LEAD SULFIDE CATALYST FOR USE IN THE BENDER (A REGISTERED TRADEMARK) SWEETENING PROCESS OF SOUR PETROLEUM PRODUCTS. THE LEAD SULFIDE CATALYST COMPRISES A CARRIER OF PARTICULATE INERT SOLIDS AND A RELATIVELY DRY EXPOSED COATING RESIDING ABOUT THE EXTERIOR SURFACE OF THE SOLIDS THE COATING IS FORMED OF A MIXTURE OF SODIUM SULFIDE AND LEAD OXIDE REACTED IN THE PRESENCE OF AN AQUEOUS SOLUTION OF SODIUM SILICATE BINDER, PREFERABLY THE SODIUM SULFIDE IS INTRODUCED IN A STOICHIOMETRIC AMOUNT RELATIVE TO THE LEAD OXIDE IN THE MIXTURE. THE CATALYST CAN BE PROTECTED FROM OXIDIZING GASES OR MOISTURE BY A HYDROCARBON SOLUBLE COVERING ENCLOSING THE COATING ON THE CARRIER. FOR EXAMPLE THE COATING MAY BE A HIGH-MELTING POINT NATURAL, PETROLEUM OR SYNTHETIC WAX.

    Abstract: CATALYTIC CONVERSION OF PETROLEUM FEEDSTOCKS, SUCH AS THE CRACKING OF A GAS OIL IN A VERTICAL TRANSPORT REACTOR, IS IMPROVED BY EFFECTING RAPID SEPARATION OF CATALYST FROM REACTOR EFFLUENT AND REGENERATING CATALYST IN A MULTI-STAGE FLUID-BED SYSTEM. A HIGHER YIELD OF DESIRABLE PETROLEUM PRODUCTS AND A LOWER CARBON LEVEL ON SPENT CATALYST ARE REALIZED. PARTIAL REGENERATION OF SPENT CATALYST IS EFFECTED IN A FIRST DILUTE-PHASE REGENERATION STAGE, PERMITTING SUBSEQUENT USE OF A HIGH REGENERATION TEMPERATURE IN ORDER TO REACH AN ACCEPTABLY LOW CARBON LEVEL ON REGENERATED CATALYST WITHOUT HARM TO SENSITIVE CONVERSION CATALYSTS.

    Abstract: FRESH PLATINUM REFORMING CATALYST IS PRETREATED BY INITIALLY CONTACTING THE CATALYST WITH HYDROGEN AND REFORMING NAPHTHA CONTAINING AT LEAST ABOUT 200 PARTS PER MILLION SULFUR AT A TEMPERATURE BETWEEN ABOUT 700 AND ABOUT 750*F., A PRESSURE BETWEEN ABOUT 200 AND ABOUT 600 P.S.I.G. AND A SPACE VELOCITY BETWEEN ABOUT 1 AND ABOUT 3 W./W./HR. THE TEMPERATURE IS THEN RAISED TO BETWEEN ABOUT 800 AND ABOUT 850*F. OVER A PERIOD BETWEEN ABOUT 2 AND ABOUT 7 HOURS AFTER WHICH THE FLOW NAPHTHA IS DISCONTINUED AND THE CATALYST IS CONTACTED WITH INERT GAS (PREFERABLY NITROGEN) AT A TEMPERATURE BETWEEN ABOUT 800 AND ABOUT 850*F., AND A PRESSURE BETWEEN ABOUT 25 AND ABOUT 150 P.S.I.G. FOR A TIME BETWEEN ABOUT 8 AND ABOUT 24 HOURS. THE CATALYST IS THEN AGAIN CONTACTED WITH SULFUR-CONTAINING REFORMING NAPHTHA UNDER THE SAME PRESSURE AND SPACE VELOCITY CONDITIONS AS BEFORE AND THE TEMPERATURE IS GRADUALLY RAISED TO THE RANGE OF BETWEEN ABOUT 890 AND ABOUT 940*F. OVER A PERIOD OF BETWEEN 2 AND ABOUT 7 HOURS, AT THE END OF WHICH TIME THE CATALYST IS AGAIN SUBJECTED TO CONTACT WITH INERT GAS FOR AN ADDITIONAL PERIOD OF BETWEEN ABOUT 8 AND ABOUT 24 HOURS. FOLLOWING THE FINAL INERT GAS SOAK, THE CATALYST IS READY FOR USE IN REFORMING NAPHTHA OF LOW SULFUR CONTENT IN A CONVENTIONAL MANNER.
