Hydrodesulfurizing crude petroleum with a desulfurizing catalyst on trihydrate bauxite

Claim 1

A PROCESS FOR THE HYDROCARBON DESULPHURIZATION OF CRUDE PETROLEUM WHICH COMPRISES PASSING THE CRUDE PETROLEUM TO A REACTING ZONE WHEREIN IT IS CONTACTED IN THE PRESENCE OF HYDROGEN AND A TEMPERATURE WITHIN THE RANGE OF 750 TO 850* F. AND AT A PRESSURE WITHIN THE RANGE OF 500 TO 1500 P.S.I. GA, WITH A CATALYTIC AGENT SELECTED FROM THE CLASS CONSISTING OF MIXTURES OF THE OXIDE AND COBALT AND MOLBDENUM IN CHEMICAL COMPOUNDS OF COBALT AND MOLYBDENUM AND OXYGEN, THE MOLYBDENUM CONTENT OF THE CATALYST EXPRESSED AS MO03 BEING BETWEEN 1 AND 15% BY WEIGHT, AND THE COBALT CONTENT EXPRESED AS CO0 BEING BETWEEN 0.2 AND 3% BY WEIGHT, DISPERSED ON A TRIHYDRATE BAUXITE WHICH HAS BEEN HEATED FOR AT LEAST TWO HOURS AT A TEMPERATURE OF ABOUT 550* C AND WHICH AFTER HEATING HAS A SURFACE AREA GREATER THAN 120 SQ.M/GM. AS MEASURED BY THE NITROGEN ADSORPTION METHOD OF BRAUNAUER, EMMETT AND TELLER, IN TEMPERATURE AND PRESSURE IN THE REACTION ZONE BEING CONROLLED SO THAT THE BREAKDOWN OF THE CRUDE PRETROLEUM IS SUBSTANTIALLY CONFINED SULPHUR COMPOUNDS CONTAINED IN THE GENATION OF ORGANIC SULPHUR COMPOUNDS CONTAINED IN THE CRUDE PETROLEUM INTO HYDROGEN SULFIDE AND LOWER BOILING CARBON COMPOUDS.
