  • HIGH FLUX AND SELECTIVITY SAPO-34 MEMBRANES FOR CO2/CH4 SEPARATIONS
    Publication number: 20070265484
    Abstract: 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.

  • Membranes for highly selective separations
    Publication number: 20060079725
    Abstract: The present invention provides modified molecular sieve membranes with improved CO2/CH4 separation selectivity and methods for making such membranes. The molecular sieve membranes are modified by adsorption of a modifying agent, such as ammonia, within and/or on the membrane.

  • High-selectivity supported SAPO membranes
    Publication number: 20050204916
    Abstract: SAPO membranes and methods for their preparation and use are described. The SAPO membranes are prepared by contacting at least one surface of a porous membrane support with an aged synthesis gel. A layer of SAPO crystals is formed on at least one surface of the support. SAPO 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.
