    Abstract: A catalyst useful for reforming a naphtha feed at reforming conditions which comprises an iridium component dispersed throughout and bound within an alumina support matrix, a platinum component dispersed upon said iridium-containing alumina support, and halogen. In all of its aspects, the iridium component will remain in its dispersed state, without significant agglomeration, when subjected to temperature in the presence of oxygen for extended periods sufficient to agglomerate presently known halogenated platinum-iridium catalysts. This catalyst is prepared in an initial step by dispersing the iridium within the alumina matrix, and then calcining the iridium-containing alumina at high temperature to bind the iridium within the alumina support matrix. The platinum, or platinum and additional metal promoters, especially rhenium, is then impregnated upon the iridium-alumina support. This catalyst can be used in reforming at reforming conditions to provide high activity, high activity maintenance, high sulfur tolerance, low coke make and high C.sub.5 + liquid volume yield.

    Abstract: Processes for the simultaneous desulfurization and hydroconversion of heavy carbonaceous feeds, including various sulfur-containing heavy petroleum oils, are disclosed. These feeds are contacted with alkali metal hydroxides in a conversion zone, in the presence of added hydrogen, and at elevated temperatures, whereby the feeds are substantially desulfurized, while at the same time significant upgrading of these feedstocks is obtained as demonstrated by decreased Conradson carbon, increased API gravity, and the conversion of a substantial portion of the 1,050.degree. F+ portion of the feedstream. In addition, methods for the regeneration of alkali metal hydroxides from the alkali metal salts produced in the conversion zone are disclosed.
