Hydrocarbon conversion catalysts com prising molybdenum sulfide and nickel sulfide dispersed within alumina

Claim 1

THE METHOD FOR PLRODUCING A GEL CATALYST COMPRISING MOLYBDENUM SULFIDE AND NICKEL SULFIDE MICROJSCOPICALLY DISPERSED WITHIN ALUMINA WHICH COMPRISES THE STEPS: (A) FORMING A SOLUTION COMPRISING NICKEL CHLORIDE, MOLYBDENUM PENTACHLORIDE AND ALUMINUM CHLORIDE, (B) ADDING TO SAID SOLUTIN FROM ABOUT 1.0 TO 5.0 MOLS OF AT LEAST ONE OXIRANE CONTAINING FROM 2 TO 3 CARBON ATOMS PER MOLECULE PER MOL OF CHLORIDE ION, THEREBY FORMING A HYDROGEL, (C) DEHYDRATING SAID HYDROGEL TO A GEL BY THE STEPS COMPRISING: (C) DEHYDRATING SAID HYDROGEL TO A GEL BY THE STEPS COMPRISING: (1) PARTIALLY DRYING SAID HYDROGEL AT A TEMPERATURE BELOW ABOUT 400*F., (2) CONTACTING THE PARTIALLY DRIED HYDROGEL WITH HEATED HYDROGEN IN THE ABSENCE OF A SULFURCONTAINING COMPOUND TO A TEMPERATURE IN THE RANGE OF FROM ABOUT 800* TO ABOUT 1150*F., THEREBY COMPLETING THE DEHYDRATION, AND (D) CONTACTING THE ALUMINA-MOLYBDENUM-NICKEL-CONTAINING COMPOUND WITH HYDROGEN AND A SULFUR-CONTAINING COMPOUND AT ELEVATED TEMPERATURES TO CONVERT A SUBSTANTIAL PORTION OF THE NICKEL AND MOLYBDENUM COMPONENTS TO THEIR CORRESPONDING SULFIDES.

Claim 2

THE METHOD FOR PLRODUCING A GEL CATALYST COMPRISING MOLYBDENUM SULFIDE AND NICKEL SULFIDE MICROJSCOPICALLY DISPERSED WITHIN ALUMINA WHICH COMPRISES THE STEPS: (A) FORMING A SOLUTION COMPRISING NICKEL CHLORIDE, MOLYBDENUM PENTACHLORIDE AND ALUMINUM CHLORIDE, (B) ADDING TO SAID SOLUTIN FROM ABOUT 1.0 TO 5.0 MOLS OF AT LEAST ONE OXIRANE CONTAINING FROM 2 TO 3 CARBON ATOMS PER MOLECULE PER MOL OF CHLORIDE ION, THEREBY FORMING A HYDROGEL, (C) DEHYDRATING SAID HYDROGEL TO A GEL BY THE STEPS COMPRISING: (C) DEHYDRATING SAID HYDROGEL TO A GEL BY THE STEPS COMPRISING: (1) PARTIALLY DRYING SAID HYDROGEL AT A TEMPERATURE BELOW ABOUT 400*F., (2) CONTACTING THE PARTIALLY DRIED HYDROGEL WITH HEATED HYDROGEN IN THE ABSENCE OF A SULFURCONTAINING COMPOUND TO A TEMPERATURE IN THE RANGE OF FROM ABOUT 800* TO ABOUT 1150*F., THEREBY COMPLETING THE DEHYDRATION, AND (D) CONTACTING THE ALUMINA-MOLYBDENUM-NICKEL-CONTAINING COMPOUND WITH HYDROGEN AND A SULFUR-CONTAINING COMPOUND AT ELEVATED TEMPERATURES TO CONVERT A SUBSTANTIAL PORTION OF THE NICKEL AND MOLYBDENUM COMPONENTS TO THEIR CORRESPONDING SULFIDES.
