Abstract

Separation of gaseous mixture of CO₂ and CH₄ was carried out using composite microporous glass membrane on ceramic tubing of which permeability are greater than that of the composite membrane by a factor of 10⁸.
The maximum separation. factor was obtained with composite membrane made, of casting solution of which ratio of B₂O₃ and SiO₂ was 1/4.
Composite membrane coated less than 5 times shows no ability of separation.
Carbon dioxide seems permeate through composite membrane obtained with decreased content of B₂O₃ (B₂O₃ : SiO₂= 1 : 14) by the surface diffusion mechanism on the pore.
