MIXED MATRIX MEMBRANE FOR SEPARATION OF GASES

摘要

An improved mixed matrix membrane for the separation of gases comprises polyethylene glycol, silicone rubber and activated carbon on a porous support. The membrane preferably also comprises a carbonate such as potassium carbonate. The gases which may be separated by the membrane include mixtures of oxygen and nitrogen and mixtures of carbon dioxide and nitrogen. Membranes of this design may be used in processing natural gas or other gases.
