Production of sweet naphthas from hydrocarbon mixtures by hydrofining the hydrocarbon mixture followed by contacting the hydrocarbon product with a composition containing cobalt and molybdenum

Claim 1

THE PROCESS FOR PRODUCING SPECIAL SOLVENT NAPHTHAS FROM PETROLEUM HYDROCARBON MIXTURES CONTAINING AT LEAST ABOUT 1.0 WEIGHT PERCENT TOTAL SULFUR WHICH COMPRISES SEPARATING A VIRGIN NAPHTHA FRACTION HAVING AN END BOILING POINT OF ABOUT 425* F. FROM SAID MIXTURES SUBJECTING SAID FRACTION TO CATALYTIC HYDRODESULFURICATION IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF MOLYBDATE, COBALT OXIDE-MOLYBDENA-ALUMINA AND CHROMIAMOLYBDENA-ALUMINA AT TEMPERATURES OF ABOUT 500 TO 800* F. UNDER CONDITIONS WHEREBY SAID SULFUR COMPOUNDS ARE CONVERTED TO HYDROGEN SULFIDE, SEPARATING HYDROGEN SULFIDE TEREFORM TO PRODUCE A HYDRODESULFURIZED PRODUCT, SUBJECTING SAID HYDRODESULFURIZED PRODUCT TO CHEMICAL TREATMENT BY CONTACT IN THE ABSENCE OF HYDROGEN AT TEMPERATURES OF ABOUT 400 TO 500* F. IN THE PRESENCE OF A CONTACT MATERIAL SELECTED FROM THE GROUP CONSISTING OF COBALT MOLYBDATE, COBALT OXIDE-MOLYBDENA-ALUMINA AND CHROMIAMOLYBDENA-ALUMINA, AND SEPARATIING AN ODOR-FREE PRODUCT CHARACTERIZED BY ITS ABILITY TO PASS THE DISTILLATION-CORROSION TEST.
