چکیده:

SAPO-34 membrane was synthesized on -AL2O3 tubular support by hydrothermal synthesis in a Teflon-lined steel autoclave. Zero N2 permeation before calcination implied relative continuity of synthesized layer while The SEM andXRD analyses confirmed SAPO-34 formation on the support with 20 μm layer thickness and cubic crystals. The synthesized membrane was able to enrich CO2 molar fraction up to 0.93 from an equimolar mixture of methane and carbon dioxide.
