Abstract
A method of separating at least a first gas from a gaseous mixture, in which a gaseous mixture containing a first and a second gas having different chemical compositions in an amount of at least 50% by volume based on the entire mixture is contacted with a carbonaceous porous body having a carbon content of at least 85% by weight and containing open cells in a three-dimensional network structure so that the open cells of the porous body form substantial flow passages for the gaseous mixture, thereby to adsorb at least the second gas physically on the porous body.
