Isomorphously Substituted Molecular Sieve Membranes

US Patent:
6767384, Jul 27, 2004
Filed:
Jan 19, 2001
Appl. No.:
09/766307
Inventors:
Tuan Anh Vu - Boulder CO
Richard D. Noble - Boulder CO
John L. Falconer - Boulder CO
Assignee:
The Regents of the University of Colorado - Boulder CO
International Classification:
B01J 2906
US Classification:
95 45, 502 4, 502 60, 502 64, 502 66, 502 74
Abstract:
Zeolite membranes that can be used to continuously separate components of mixtures are disclosed. The zeolite membranes are prepared by isomorphous substitution, which allows systematic modification of the zeolite surface and pore structure. Through proper selection of the basic zeolite framework structure and compensating cations, isomorphous substitution permits high separation selectivity without many of the problems associated with zeolite post-synthesis treatments. The inventive method for preparing zeolite membranes is alkali-free and is much simpler than prior methods for making acid hydrogen zeolite membranes, which can be used as catalysts in membrane reactors.

International Classification:
B01D 53/22, B05D 5/00
US Classification:
95 45, 96 11, 427244
Abstract:
A method of making a supported gas separation molecular sieve membrane. In this method a porous support, which is preferably pretreated, is contacted with a molecular sieve synthesis mixture under hydrothermal synthesis conditions. The contacting step is conducted for a shortened crystallization time period. The resulting coated porous support is calcined to yield the supported gas separation molecular sieve membrane having particularly good gas separation characteristics.

High Flux Sapo-34 Membranes For Co2/Ch4 Separation And Template Removal Method

US Patent:
2012000, Jan 12, 2012
Filed:
Apr 28, 2011
Appl. No.:
13/096225
Inventors:
John L. Falconer - Boulder CO, US
Richard D. Noble - Boulder CO, US
Begum Tokay - Istanbul, TR
Yanfeng Zhang - Shanghai, CN
Assignee:
The Regents of the University of Colorado, a body corporate - Denver CO
International Classification:
B01D 71/02, B05D 3/02, B01D 53/22
US Classification:
95 51, 96 11, 95 45, 427226
Abstract:
The present invention provides methods for making improved zeolite and crystalline silicoaluminophosphate (SAPO) membranes, in particular SAPO-34 membranes, on a porous support through improved removal of the organic structure-directing templating agent. A calcining step is performed in an oxygen free atmosphere, such as under a vacuum or inert gas, to remove the organic templating agent. By removing the templating agent in the absence of oxygen, the calcination step can remove a greater amount of the templating agent than comparable template removal steps conducted in the presence of oxygen and the calcination step can be conducted at significantly lower temperatures. The membranes of the present invention provide increased permeance while maintaining comparable selectivity for gas separations, particularly carbon dioxide (CO) and methane (CH) separations and separations at high temperatures.

Ceramic-Zeolite Composite Membranes And Use For Separation Of Vapor/Gas Mixtures

US Patent:
5464798, Nov 7, 1995
Filed:
Feb 24, 1994
Appl. No.:
8/201472
Inventors:
Meng-Dong Jia - Beijing, CN
Richard D. Noble - Boulder CO
John L. Falconer - Boulder CO
International Classification:
B01J 2906
US Classification:
502 64
Abstract:
A zeolite composite membrane apparatus and method for preparing a novel continuous zeolite composite membrane. The method described results in formation of a thin polycrystalline continuous zeolite layer on the inner wall of a substrate container. The container may be a cylinder. After calcination, the zeolite composite membrane shows high permeability and high selectivity for single gas and for vapor/gas mixtures. The zeolite composite membrane formed has improved separation characteristics of shape selectivity and selective adsorption. The geometry of the membrane provides a high permeation area to volume ratio. The membrane is useful for high temperature gas separations and for membrane reactor applications.
