ABSTRACT:
Reforming is effected with a combination of a primary supported noble-metal catalyst and a catalyst containing one or more medium pore non-zeolite molecular sieves (MP-NZMS). The latter reforming and dehydrocyclization comprise a Group VIII metal and at least one bound MP-NZMS characterized in the calcined form by an adsorption of isobutane of at least 2 percent by weight at a partial pressure of 500 torr and a temperature of 20.degree. C. and characterized by an adsorption of triethylamine less than about 5 percent by weight at a partial pressure of 2.6 torr and a temperature of 22.degree. C., The MP-NZMS catalyst binder preferably is alumina and/or silica, and the Group VIII metal preferably is platinum.
