    摘要: 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.

    摘要: The invention provides chemically activated valves based on crystalline molecular sieve membranes. Adsorption of a swelling agent within the pores of the molecular sieve crystals limits transport through the membrane. Desorption of the swelling agent can re-establish transport through the membrane. This valving mechanism can be used in methods for storing and dispensing various substances.

    摘要: 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 (CO2) and methane (CH4) separations and separations at high temperatures.
