Conversion of hydrocarbons with nickel oxide-molybdenum oxide catalyst

Claim 1

A PROCESS FOR THE CATALYTIC CONVERSION OF MINERAL OIL HYDROCARBON STOCKS, WHICH COMPRISES PASSING SAID HYDROCARBON STOCK IN ADMIXTURE WITH HYDROGEN THROUGH A CATALYST CONTACTING ZONE MAINTAINED AT A TEMPERATURE BETWEEN ABOUT 600* AND 1200* F. AND A PRESSURE BETWEEN ABOUT ATMOSPHERIC AND 5000 P.S.I., SAID CATALYST CONTACTING ZONE CONTAINING A CATALYST CONSISTING ESSENTTIALLY OF A MINOR PROPORTION OF NICKEL OXIDE PLUS MOLYBDENUM OXIDE AND A MAJOR PROPORTION OF AN ADSORBENT CARRIER, SAID CATALYST HAVING BEEN PREPARED BY FIRST IMPREGNATING AN ADSORBENT CARRIER WHICH IS ESSENTIALLY ALUMINA WITH AN AQUEOUS SOLUTION OF A MOLYBDENUM COMPOUND, HEATING THE ONCE-IMPREGNATED CARRIER AT AN ACTIVATION TEMPERATURE ABOVE ABOUT 400* C. TO THEREBY ACTIVATE THE ALUMINA AND DECOMPOSE SAID MOLYBDENUM COMPOUND TO THE OXIDE FORM THEREAFTER IMPREGNATING SAID CARRIER WITH AN AQUEOUS SOLUTION OF A NICKEL COMPOUND AND HEATING THE TWICEIMPRENATED CARRIER AT AN ACTIVATION TEMPERATURE ABOVE ABOUT 400* C. TO THEREBY ACTIVATIVE THE ALUMINA AND DECOMPOSE SAID NICKEL COMPOUND TO THE OXIDE FORM.
