    摘要: This invention comprises a reforming catalyst and process with an unsulfided catalyst comprising Zeolite L, in which the cationic sites have been exchanged to contain potassium or barium or both; a Group VIII noble metal and rhenium, where the ratio of noble metal to rhenium is from about 0.1:1 to about 10:0. This catalyst gives improved selectivity toward aromatics formation and has improved sulfur tolerance compared to other L zeolite reforming catalysts.

    摘要: A deactivated catalyst comprising a nonacidic zeolite and a Group VIII metal is regenerated by a two-step carbon burn process. The first oxidation step contacts the nonacidic zeolite catalyst with a halogen-free gaseous stream comprising oxygen and an inert gas at a first temperature sufficient to combust carbonaceous material while maintaining a substantial portion of the active Group VIII metal surface area withn the micropores of the nonacidic zeolite for a first period of time sufficient to substantially complete combustion of at least a portion the carbonaceous material at the first temperature. The second step contacts this nonacidic zeolite catalyst with a gaseous stream comprising oxygen and an inert gas at a second temperature sufficient to combust any remaining carbonaceous material for a second period of time sufficient to maintain a substantial portion of the active Group VIII metal surface area in the micropores of the nonacidic zeolite catalyst.

    摘要: A method is disclosed for reforming hydrocarbons, particularly C.sub.6 -C.sub.10 hydrocarbons, to aromatics, by passing the hydrocarbons over a dehydrocyclization catalyst at dehydrocyclization conditions. The catalyst comprises a non-acidic large pore zeolite having a Group VIII metal and an alkaline earth metal, said alkaline earth metal having been impregnated onto the zeolite by contacting the zeolite with an alkaline earth metal solution of a concentration sufficient to result in the zeolite having an alkaline earth metal content of less than about 2% by weight of the zeolite.
