ABSTRACT:
A method is provided for the preparation of a synthetic, non-composited microporous membrane comprising a continuous array of crystalline molecular sieve material. A non-porous forming surface is contacted, under crystallization conditions, with a chemical mixture capable of forming the molecular sieve material. After a layer of the molecular sieve material is crystallized on the forming surface, the layer and the forming surface are recovered from the chemical mixture and the layer is separated from the forming surface.
