Notes:
The utility of anisotropic ultrafiltration membranes in gas separation has been examined. These membranes consist of a thin (0.2-2μ) barrier layer supported upon a more porous supporting substructure. Gases permeate these membranes by a Knudsen diffusion mechanism. Permeabilities from 0.1 to 0.4 cm sec-1 cm Hg-1 were obtained. These values are 104 to 105 higher than most conventional gas separation membranes. These membranes may be useful in several gas separation processes.
