ABSTRACT:
The present invention relates to a method of forming a zeolite membrane. The method includes forming an aqueous-based or an alcohol-based sol which can form a zeolite. The sol composition is then disposed on a porous support. The porous support and the sol composition are exposed to an atmosphere and to a temperature sufficient to cause the sol composition to hydrothermally crystallize, thereby forming the zeolite membrane.
