Abstract: A PROCESS FOR REACTIVATION, INCLUDING CHLORINATION, OF A FIXED BED OF CARBON-FOULED, PLATINUM GROUP METAL- AND RHENIUM-CONTAINING, ALUMINA-SUPPORTED CATALYST IS DISCLOSED WHICH INVOLVES CONTACTING THE CATALYST WITH AN OXYGEN-CONTAINING GAS, THEN WITH A GASEOUS STREAM CONTAINING INERT GAS, OXYGEN AND VAPOROUS CHLORINE-CONTAINING AGENT UNTIL AT LEAST ABOUT 0.2% CHLORINE HAS BEEN ADDED TO THE CATALYST BASED ON THE TOTAL WEIGHT OF CATALYST IN THE BED. CONTACT OF THE CATALYST IS THEN CONTINUED WITH A GASEOUS STREAM CONTAINING INERT GAS, OXYGEN AND A MINOR AMOUNT OF WATER VAPOR TO DISTRIBUTE CHLORINE IN THE CATALYST BED.

Abstract: A METHOD FOR MONITORING THE HYDROGENATION-DEHYDROGENATION AND/OR ACIDIC ACTIVITIES OF A CATALYST COMPRISING PLATINUM AND ALUMINA IS DISCLOSED. THE CATALYST IS USED TO PROMOTE THE CONVERSION, E.G., REFORMING, OF HYDROCARBON FEEDSTOCK INTO HYDROCARBON EFFUENT. THE EFFUENT CAN THEN BE ANALYZED FOR TOLUENE AND METHYLCYCLOHEXANE (MCH), AND N-HEXANE, 2,2-DIMETHYLBUTANE, N-HEPTANE AND 3,3-DIMETHYLPENTANE. SELECTED RATIOS OF THESE SIX COMPONENTS CHARACTERIZED THE STATE OF THE ACTIVITY OF THE CATALYST.
