摘要： A highly cost-efficient method and process for producing oxygen from a gaseous mixture such as air results in substantial energy savings compared to conventional methods. The gaseous mixture is fed to a membrane absorber in which oxygen from the gas is absorbed, through a first membrane by an oxygen-absorbing liquid that possesses suitable absorption and desorption properties. The resulting oxygen-rich carrier liquid is fed to a membrane desorber in which oxygen from the liquid is desorbed through a second membrane, suitably with the aid of a vacuum. The oxygen product suitably has greater than 95% purity, or greater than 99% purity.

摘要： SAPO-34 membranes and methods for their preparation and use are described. The SAPO-34 membranes are prepared by contacting at least one surface of a porous membrane support with a synthesis gel. The Si/Al ratio of the synthesis gel can be from 0.3 to 0.15. SAPO-34 crystals are optionally applied to the surface of the support prior to synthesis. A layer of SAPO-34 crystals is formed on at least one surface of the support. SAPO-34 crystals may also form in the pores of the support. SAPO-34 membranes of the invention can have improved selectivity for certain gas mixtures, including mixtures of carbon dioxide and methane.

摘要： 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.
