초록

Reforming is effected with a combination of a primary supported noble-metal catalyst and a catalyst containing one or more medium-pore non-zeolitic molecular sieves (MP-NZMS). The latter reforming and dehydrocyclization catalysts 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°C. and characterized by an adsorption of triethylamine less than about 5 percent by weight at a partial pressure of ...
