A membrane having a preselected pore type which is suited for separating processes comprising a shaped body formed by heating a mixture of finely ground carbonaceous material with a binder composed of about 5 to 20% by weight natural or synthetic elastomer or a mixture of both and of about 1 to 20% by weight of thermoplastic material to about 400.degree. to 1400.degree. C. in an inert atmosphere at a rate of temperature increase between 0.1.degree. and 10.degree. C./min. The membranes are useful for a wide range of selective chemical and physical separation operations of different materials.
