Continuous SAPO-34 membranes with low concentrations of non-zeolite pores were synthesized by in situ crystallization on porous stainless steel and ฮฑ-Al2O3 supports. These membranes separated CO2 from CH4 with selectivity as high as 67 at 297K for a CO2 permeance of 1.6 ร 10โ7 mol/m2 sPa. The membra
