Abstract: Naphtha feed stocks are converted to high octane products in a long cycle semi-regenerative operation utilizing a catalyst comprising alumina in association with 0.15 to 0.75 weight percent platinum, 0.15 to 0.45 weight percent iridium and 0.3 to 2.0 weight percent chlorine, each based on total catalyst, the surface area of the platinum and iridium on the alumina being at least about 200 square meters per gram of platinum and iridium as determined by carbon monoxide chemisorption techniques. The catalyst should contain less than about two atoms of sulfur per atom of platinum and iridium and be substantially free of alkali and alkaline earth metal constituents.

Abstract: Hydrocarbon materials are converted to useful products by contacting the same at elevated temperatures with a catalyst comprising a refractory support in association with greater than 0.1 wt. % iridium, and 0.1 - 1.0 wt. % of at least one additional metal. The iridium and additional catalyst metal, preferably platinum, are present on the surface of the support in the form of highly dispersed polymetallic clusters with metal surface areas of at least 200 square meters per gram of metal. The catalyst is particularly effective for promoting naphtha reforming operations.

Abstract: NAPTHA FEED STOCKS ARE CONVERTED TO HIGH OCTANE PRODUCTS AT HIGH SEVERITY CONDITIONS UTILIZING A CATALYST COMPRISNG ALUMINA IN ASSOCIATION WITH 0.15 TO 0.75 WEIGHT PERCENT PLATINUM, 0.15 TO 0.45 WEIGHT PERCENT IRIDIUM AND 0.3 TO 2.0 WEIGHT PERCENT CHLORINE, EACH BASED ON TOTAL CATALYST, THE SURFACE AREA OF THE PLATINUM AND IRIDIUM ON THE ALUMINA BEING AT LEAST ABOUT 200 SQUARE METERS PER GRAM OF PLATINUM AND IRIDIUM AS DETERMINED BY CARBON MONOXIDE C CHEMISORPTION TECHNIQUES. THE CATALYST SHOULD CONTAIN LESS THAN ABOUT TWO ATOMS OF SULFUR PER ATOM OF PLATINUM AND IRIDIUM AND BE SUBSTANTIALLY FREE OF ALKALI AND ALKALINE EARTH METAL CONSTITUENTS.

Abstract: A CATALYTIC REFORMING PROCESS WHEREIN NAPHTHA FEED STREAMS, BOILING FROM ABOUT 80 TO 450*F., AND COMPRISING NAPHTHENES, PARAFFINS AND AROMATICS, ARE CONTACTED, IN AN INITIAL REACTION ZONE, WITH A HYDROGEN CONTAINING GAS, IN THE PRESENCE OF A CATALYST COMPRISING PD, OR PD AND A GROUP I-B METAL SUPPORTED ON A REFRACTORY OXIDE, AND PASSED INTO A TAIL ZONE WHEREIN THE FEED STREAM IS AGAIN CONTACTED WITH A CATALYST AND THEREBY FURTHER REACTED TO PRODUCE A HIGH OCTANE NUMBER PRODUCT. IN A PREFERRED EMBODIMENT THE GROUP I-B METAL IS AU.
