Abstract: Abstract of the Disclosure In order to provide enough permeability (air or liquid through-put) in a porous molded body of carbon made from a mixture of carbon powder and a binder, a first "green" body (a body of the kind that has been fired heretofore, in its green state before firing) is broken up into small pieces with the help of a jaw crusher in a manner providing coarse particles and a fraction of uniform size (largest particle diameter not more than twice the smallest) in the overall range between 0.2 and 10 mm effective diameter is used to make a second green body of molded shape by placing it in a die and applying a pressure which may be light or heavier according to the desired degree of permeability.  The second green body is then coked in vacuum or in an inert atmosphere at a temperature in the range between 600 to 1000°C to produce a strong body through which gas and liquid may pass with a facility far exceeding what has been accomplished before with a body of comparable strength.  The resulting porous bodies are particularly useful as filters for flowing gases. Moreover they can filter hot gas flows, being resistant to high temperatures and marked temperature changes.
