Reforming and hydrofining process

Claim 1

IN THE OPERATION OF AN INTEGRATED HYDROFINER EMPLOYING A COBALT OXIDE-MOLYBDENUM OXIDE-ON-ALUMINA CATALYST AND A HYDROFORMER EMPLOYING A PLATINUM GROUP METAL-ON-ALUMINA CATALYST, THE IMPROVEMENT IN ACTIVATING SAID OXIDE-ON-ALUMINA CATALYST WHICH COMPRISES IN COMBINATION, CHARGING A LOW SULFUR NAPHTHA FEED AND HYDROGEN TO THE HYDROFORMER AT NORMAL HYDROFORMER CONDITIONS; WITHDRAWING REACTION PRODUCTS FROM THE HYDROFORMER, COOLING THE SAME, AND SEPARATING NORMALLY LIQUID HYDROFORMED PRODUCTS FROM HYDROGEN-RICH GAS, RECYCLING A PORTION OF SAID GAS TO THE HYDROFORMER, CHARGING FRESH HIGH SULFUR NAPHTHA FEED AND A PORTION OF THE HYDROGENCONTAINING GAS SEPARATED FROM SAID HYDROFORMER PRODUCTS TO THE HYDROFINING REACTION ZONE AT NORMAL HYDROFINING CONDITIONS, ADDING 0.1 TO 1.0 WT. PERCENT OF A SULFIDING AGENT BASED ON HIGH SULFUR NAPHTHA FEED AND SELECTED FROM THE GROUP CONSISTING OF CS2 AND LOWER ALKYL MERCAPTANS TO SAID HYDROFINING REACTION ZONE, COOLING THE EFFLUENT FROM THE HYDROFINER TO CONDENSE THE LIQUID PRODUCTS, SEPARATING THE LIQUID PRODUCTS FROM THE GASEOUS PRODUCTS, WITHDRAWING THE LATTER FROM THE SYSTEM AND RECYCLING THE LIQUID PRODUCTS CONTAINING SAID SULFIDING AGENT TO SAID HYDROFINING REACTION ZONE UNTIL SAID OXIDE-ONALUMINA CATALYST HAS ABSORBED FROM ABOUT 20 TO 30 WT. PERCENT OF THE STOICHIOMETRIC QUANTITY OF SULFUR NECESSARY TO CONVERT SAID OXIDE-ON-ALUMINA CATALYST TO SULFIDE.
