FIELD: chemistry.
SUBSTANCE: present invention can be used in the processes of separating gas mixtures, containing carbon dioxide gas and non-oxygen systems, such as hydrogen, inferior hydrocarbons, nitrogen, methane, ethylene, acetylene etc. The composite material for separating gases has a layer of porous substrate, with porosity not less than 30% and a selective layer made from a foil of foamed graphite with a nitrate history, put on the substrate.
EFFECT: high selective ability of the membrane with high flow output of hydrocarbons and hydrogen.
