ABSTRACT:
Novel membranes comprise crystals of a zeo-type material carried by a porous support. The crystal growth of the zeo-type material is essentially continuous over the pores of the support and the zeo-type material is crystallized directly from and bonds directly to the support. Membranes may be prepared by immersing the support in a synthesis gel, crystallizing the gel, removing the support, and repeating these steps at least once.
