TITLE Process for synthesis of oriented molecular sieve membranes with improved separation performance PRIMARY INVENTORS Michael Tsapatsis, Ph.D. DESCRIPTION A modified seeded growth method was developed that allows the fabrication of zeolite MFI films that have straight 5.5Angstrom channels perpendicular to the membrane surface. The membranes show improved separation performance. For example, they have the highest permeance and selectivity reported up to now for xylene isomer separation. APPLICATIONS Separation of hydrocarbon mixtures, membrane reactors ADVANTAGES The membranes show highest flux and selectivity compared to those reported before. The membranes are potentially more resistant to cracking compared to those reported before.
