Hydrodesulfurization catalyst and the method of manufacture

Claim 1

A METHOD OF PREPARING COBALT-MOLYBDENUM CATALYST CONSISTING ESSENTIALLY OF 1% TO 5% COBALT OXIDE BY WEIGHT AND 2% TO 20% MOLYBDENUM OXIDE BY WEIGHT ON A CARRIER CONSISTING ESSENTIALLY OF ALUMINA WHICH COMPRISES WETTING A UNIFORM MIXTURE OF SOLID HYDRATED ALUMINA AND A SOLID COMPOUND IF MOLYBDENUM WHICH AFTER HEATING PROVIDES MOLYBDENUM OXIDE WITH AN AQUEOUS SOLUTION OF A COBALT SALT OF A STRONG MINERAL ACID TO ACHIEVE UIFORM DISTRIBUTION OF THE COBALT SALT THROUGHOUT THE SOLIDS, THE PH OF SAID SOLUTION BEING LESS THAN 7 AND THE AMOUNT OF WATER THEREIN BEING IN EXCESS OF 10% OF THE WEIGHT OF THE MIXTURE, AND CALCINING THE MIXTURE AT A TEMPERATURE SUFFICIENT TO AT LEAST PARTIALLY ACTIVATE THE ALUMINA BY DRIVING OFF WATER OF HYDRATION AND ATO STABILIZE THE COBALT AND MOLYBDENUM BY CONVERTING COMPOUNDS OF THESE METALS TO THEIR RESPECTIVE OXIDES.

Claim 2

A METHOD OF PREPARING COBALT-MOLYBDENUM CATALYST CONSISTING ESSENTIALLY OF 1% TO 5% COBALT OXIDE BY WEIGHT AND 2% TO 20% MOLYBDENUM OXIDE BY WEIGHT ON A CARRIER CONSISTING ESSENTIALLY OF ALUMINA WHICH COMPRISES WETTING A UNIFORM MIXTURE OF SOLID HYDRATED ALUMINA AND A SOLID COMPOUND IF MOLYBDENUM WHICH AFTER HEATING PROVIDES MOLYBDENUM OXIDE WITH AN AQUEOUS SOLUTION OF A COBALT SALT OF A STRONG MINERAL ACID TO ACHIEVE UIFORM DISTRIBUTION OF THE COBALT SALT THROUGHOUT THE SOLIDS, THE PH OF SAID SOLUTION BEING LESS THAN 7 AND THE AMOUNT OF WATER THEREIN BEING IN EXCESS OF 10% OF THE WEIGHT OF THE MIXTURE, AND CALCINING THE MIXTURE AT A TEMPERATURE SUFFICIENT TO AT LEAST PARTIALLY ACTIVATE THE ALUMINA BY DRIVING OFF WATER OF HYDRATION AND ATO STABILIZE THE COBALT AND MOLYBDENUM BY CONVERTING COMPOUNDS OF THESE METALS TO THEIR RESPECTIVE OXIDES.
