Claim 1
Independent Claim

PROCESS FOR THE HYDROGENATION OF AROMATICS AND SULFUR-BEARING HYDROCARBON OILS WHICH COMPRISES CONTACTING THE AROMATICS AND SULFUR-BEATING HYDROCABON OIL UNDER HYDROGENATION CONDITIONS OF PRESSURE ABOVE ABOUT 20 ATMOSPHERS AND TEMPERATURE BETWEEN ABOUT 360 AND 450* C. IN THE PRESENCE OF ADDED HYDROGEN WITH A SUPPORTED TUNGSTEN-MOLYBDENUM-NICKEL CATALYST PREPARED BY IMPREGNATING AN ALUMINA CARRIER WITH SOLUBLE COMPOUNDS OF TUNGESTEN, MOLYBDENUM AND NICKLE COVERTIBLE TO THE OXIDE UPON CALCUNATION, THE MOLE RATIO OF NICKLE TO MOLYBDENUM BEING BETWEEN 1/4 AND 2/3 TO 1, THE MOLE RATIO OF TUNGSTEN TO MOLYBDENUM BEING BETWEEN 1/4 AND 1 TO, 1, AND THE TOTAL METALS CONTENT BEING ABOVE ABOUT 8% BY WEIGHT, CALCINING TO COVERT THE MATEL COMPOUNDS TO THE CORRESPONDING OXIDES, AND PARTIALLY SULFIDING BY TREATMENT FOR AT LEAST 1/2 HOURS AT A TEMPERATURE BELOW ABOUT 215* C. BUT ABOVE ABOUT 110* C. WITH A MIXTURE OF HYDROGEN AND HYDROGEN SULFINE IN A MOLE RATIO BETWEN 1:1 AND 40:1

Claim 3
Dependent Claim
134 words
PROCESS FOR THE PREPARATION OF A CATALYST HAVING HIGH ACTIVITY FOR THE HYDROGENATION OF AROMATICS IN AROMATIC AND SULFUR-BEARING HYDROCARBON OILS WHICH COMPRISES IMPREGENATING AN ALUMINA CARRIER WITH SOLUBLE COMPOUNDS OF TUNGSTEN, MOLYBDENUM, AND NICKLE COVERTIBLE TO THE OXIDE UPON CALCINATION, THE MOLE RATIO OF SAID MATERIAL BEING ABOUT 1:1:1, AND THE TOTAL METAL CONTENT BEING ABOVE 8% BY WEIGHT, CALCINING TO CONVERT THE METAL COMPOUNDS TO THE CORRESPONDING OXIDES, FURTHER IMPREGNATING THE CALCINED MATERIAL WITH MOLYBDENUM TO BRING SAID MOLE RATIO TO ABOUT 1:2:1, AGAIN CALCINING TO CONVERT THE FURTHER INCORPORATED MOLYBDENUM TO THE OXIDE, AND PARTIALLY SULFINDING BY TREATMENT FOR AT LEAST 1/2 HOURS AT A TEM PERATURE BELOW ABOUT 210 BUT ABOVE ABOUT 110* C. WITH A MIXTURE OF HYDROGEN AND HYDROGEN SULFIDEE IN A MOLE RATIO BETWEEN 1:1 AND 40:1.
