Abstract: A COPPER-IRON GROUP METAL CATALYST USEFUL IN TH CONVERSION OF THIOLS TO DISULFIDES IS PREPARED BY FORMING AN AQUEOUS SOLUTION OF SODIUM OR POTASSIUM SUKICATE, AND A SOLUBLE IRON GROUP METAL SALT, SUCH AS FERRIC CHLORIDE, AND COGELLING THE SOLUTION WITH A BASIC AGENT, SUCH AS AMMONIA, TO FORM A PRECIPITATE. THIS PRECIPIATATE IS OPTIONALLY DRIED AND/OR CALCINED BEFORE THE ADDITION THERETO OF A COPPER SALT, SUCH AS COPPER CHLORIDE. AFTER THE ADDITION OF THE COPPER SALT, THE COMPOSITE IS DRIED AND CALCINED.

Abstract: 1. A PROCESS FOR HYDRODESULFURIZING A FEED RESIDUAL OIL COMPRISING CONTACTING THE FEED OIL AND HYDROGEN WITH A HYDROSULFURIZATION CATALYST AT A TEMPERATURE OF ABOUT 600 TO ABOUT 1,000* F., A LIQUID HOURLY SPACE VELOCITY OF FROM ABOUT 0.1 TO ABOUT 10 VOLUMES OF FEED OIL PER VOLUME OF CATALYST PER HOUR AND A HYDROGEN FEED RATE OF FROM ABOUT 500 TO ABOUT 10,000 STANDARD CUBIC FEED OF HYDROGEN PER BARREL OF FEED OIL, SAID CATALYST COMPRISING A MINOR AMOUNT OF GROUP VI AND GROUP VIII METALS WITH A MAJOR AMOUNT OF AN ALUMINA CARRIER CONTAINING LESS THAN 1 WEIGHT PERCENT SILICA, SAID ALUMINA CARRIER COMPOSITED OF A FIRST ALUMINA OBTAINED BY DRYING AND CALCINING A CRYSTALLINE ALUMINA TRIHYDRATE AND A SECOND ALUMINA OBTAINED BY DRYING AND CALCINING A CRYSTALLINE ALUMINA HYDRATE CONTAINING FROM 1.2 TO 2.6 MOLS OF WATER OF HYDRATION PER MOL OF AL2O3, THE ALUMINA TRIHYDRATE COMPRISING AN AMOUNT FROM ABOUT 2 TO ABOUT 35 WEIGHT PERCENT OF THE TOTAL OF SAID HYDRATES WHICH INCREASES THE SPECIFIC HYDRODESULFURIZATION ACTIVITY OF SAID CATALYST.

Abstract: THE ON-STREAM LIFE IN A SWEETENING PROCESS USING A COPPER-IRON CATALYST IS EXTENDED BY INCORPORATING IN THE FEED A MINOR AMOUNT OF A NITROGEN CONTAINING COMPOUND HAVING THE FORMULA: R-N(-R'')-R" WHERE R, R'' AND R" CAN BE THE SAME OR DIFFERENT AND ARE SELECTED FROM HYDROGEN, A HYDROCARBON GROUP HAVING FROM 1 TO 10 CARBON ATOMS AND WHERE OPTIONALLY THE HYDROCARBON GROUPS CAN BE CYCLICIZED TO FORM A FIVE OR SIX MEMBERED HETEROCYCLIC COMPOUND. THE PREFERRED NITROGEN CONTAINING COMPOUNDS ARE AMMONIA AND PYRIDINE.
