Improving SAPO-34 membrane synthesis

Previously, SAPO-34 membranes prepared using aluminum isopropoxide (Al(O–i–Pr)3) and two templates (tetraethylammoniumhydroxide (TEAOH); dipropylamine (DPA)) were shown to separate CO2/CH4 mixtures with high fluxes at high pressures and room temperature. In this study, the synthesis was simplified,...
