Abstract
A catalytic composition comprises a metal hydrogenation- dehydrogenation component supported on a support material comprising an ultra-large pore crystalline material of high surface area and porosity. The crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., and has uniformly sized pores with a maximum perpendicular cross section of at least about 13 .ANG.. In a preferred form, the support material, which is preferably a metallosilicate such as an aluminosilicate, has the pores in a hexagonal arrangement, giving rise to a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG..
