Abstract: The catalyst comprises a small amount of rhenium and the oxides of chromium on a catalytically active alumina. The catalyst may be promoted by an oxide of an alkali metal, an oxide of an alkaline earth metal, or mixtures thereof. The catalyst is very efficient for the dehydrocyclization of paraffins and may be used in a process for reforming a petroleum hydrocarbon feedstock containing a substantial amount of paraffins, which process comprises contacting the hydrocarbon feedstock in a reforming reaction zone under reforming conditions and in the presence of hydrogen with the catalyst of the present invention.

Abstract: The catalyst comprises a component having hydrogenationdehydrogenation activity, a suitable support, and as a promoter a small amount of technetium. The support may comprise alumina and the component having hydrogenation-dehydrogenation activity and dehydrocyclization activity may be a Group VIII noble metal or a metal from Group VIA of the Periodic Table of Elements. The small amount of technetium is about 0.01 to about 2 weight percent, based on the weight of the catalyst. The process comprises contacting a petroleum hydrocarbon stream in a reforming zone under suitable reforming conditions and in the presence of hydrogen with a catalyst of the invention.

Abstract: The method comprises treating the catalyst in a reforming zone with a first oxygen-containing gas at a temperature of at least 880*F.; subsequently treating the catalyst with a second oxygencontaining gas; after purging the reforming zone with an inert gas, treating the catalyst with a hydrogen-containing gas while cooling the average catalyst temperature to a temperature of about 700*F.; introducing the petroleum hydrocarbon stream to be reformed into the reforming zone at one-half to one of the weight hourly space velocity to be employed during the reforming process; increasing the average catalyst temperature to a temperature of 850*F. at a selected rate; increasing the weight hourly space velocity to that desired for the process; and replacing the hydrogen-containing gas with hydrogen-containing recycle gas. The first oxygen-containing gas may be air while the second oxygen-containing gas may be essentially pure oxygen.
