Thin pure-silica chabazite (Si-CHA) membranes have been synthesized by using a secondary growth method on a porous silica substrate. A CO₂ permeance of 2.62 × 10⁻⁶ mol m⁻² s⁻¹ Pa⁻¹ with a CO₂/CH₄ permeance ratio of 62 was obtained through a Si-CHA membrane crystallized for 8 h using a parent gel of H₂O/SiO₂ ratio of 4.6. The CO₂ permeance through the Si-CHA membrane on a porous silica substrate was twice as high as that through the membrane synthesized on a porous alumina substrate, which displayed a similar zeolite layer thickness.
