  • SEEDED-GEL SYNTHESIS OF HIGH FLUX AND HIGH SELECTIVITY SAPO-34 MEMBRANES FOR CO2/CH4 SEPARATIONS
    Publication number: 20140352533
    Abstract: The invention provides methods for making silicoaluminophosphate-34 (SAPO-34) membranes comprising interlocking SAPO-34 crystals. In the methods of the invention, the SAPO-34 membranes are formed through in situ crystallization on a porous support using a synthesis mixture initially including a SAPO-34 forming gel and a plurality of SAPO-34 crystals dispersed in the gel. The invention also provides supported SAPO-34 membranes made by the methods of the invention. The invention also provides methods for separating a first gas component from a gas mixture, the methods comprising the step of providing a membrane of the invention.
