摘要:
A process and catalyst for catalytic cracking comprising a non-layered, ultra-large pore crystalline material. The crystalline material preferably has a benzene adsorption capacity greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. Preferred materials have a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. Preferred cracking catalysts comprise ultra-large pore materials having pore openings formed by at least 20 tetrahedrally coordinated members, most preferably with 36 or 42 tetahedrally coordinated members.
