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/AI 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.

La présente invention concerne des membranes SAPO-34 et leurs procédés de préparation et d'utilisation. Les membranes SAPO-34 sont préparées en mettant en contact au moins une surface d'un support poreux de membrane avec un gel de synthèse. Le rapport Si/Al du gel de synthèse peut aller de 0,3 à 0,15. Des cristaux SAPO-34 sont éventuellement appliqués à la surface du support avant la synthèse. Une couche de cristaux SAPO-34 est formée sur au moins une surface du support. Des cristaux SAPO-34 peuvent également se former dans les pores du support. Les membranes SAPO-34 de l'invention peuvent présenter une sélectivité améliorée pour certains mélanges de gaz, y compris des mélanges de dioxyde de carbone et de méthane.
