Organic template-free synthesis of SAPO-34 molecular sieve membranes for CO2–CH4 separation

Abstract

Continuous SAPO-34 molecular sieve membranes have been rapidly synthesized on porous α-Al2O3 supports by secondary growth in the absence of organic templates under microwave-assisted heating. The thus obtained SAPO-34 membranes exhibit CO2–CH4 separation selectivity as high as 256, with CO2 permeance higher than 1.68 × 10−6 mol m−2 s−1 Pa−1 at 295 K for a pressure drop of 0.14 MPa.
