Abstract:
The present invention is directed to an alumino-borosilicate SSZ-57 zeolite having enhanced large pore selectivity. The alumino-borosilicate SSZ-57 zeolite of the present invention is characterized as having substantially all of its aluminum atoms located within regions of the zeolite structure which form the 12 ring channels.
