Catalytic reforming, usually employed for the conversion of a naphtha to provide aromatic products, is well known in the petroleum industry. A naphtha reforming process is frequently employed in a catalytic conversion zone where a hydrocarbon-containing mixture is contacted with one or more reforming catalysts in the presence of hydrogen and the conversion zone is heated by the burning of particulate or gaseous fuel to effect the endothermal reaction. The resulting product stream from the conversion zone is usually cooled and separated into fractions with the desired products being recovered from the more highly vaporized materials.
Aromatic-hydrocarbon-containing fractions, such as naphtha, are catalytically reformed by contacting them at high temperature with a catalyst containing a Group VIII non-noble metal, particularly nickel, and a hydrogenation-dehydrogenation (hydrogen transfer) metal, particularly platinum, on a refractory oxide support. U.S. Pat. Nos. 4,013,547, 4,112,054, 4,198,268, and 4,237,184 are exemplary of the art relating to reforming.
Catalytic reforming generally is carried out at temperatures of about 800.degree.-1100.degree. F. (427.degree.-567.degree. C.), preferably about 900.degree 0b46394aab
