Continuous SAPO-34 membranes with low concentrations of non-zeolite pores were synthesized by in situ crystallization on porous stainless steel and Ξ±-Al2O3 supports. These membranes separated CO2 from CH4 with selectivity as high as 67 at 297K for a CO2 permeance of 1.6 Γ— 10βˆ’7 mol/m2 sPa. The membra

The carbonized hollow fiber membranes were prepared through gelation of polyamic acid solution, imidization and carbonization of polyamic acid (PAA) gel by mainly controlling the gelation conditions. The microstructure of the carbonized membranes was evaluated by micropore volume, which was measured
