  • Method of improving the selectivity of carbon membranes by chemical carbon vapor deposition
    Patent number: 5695818
    Abstract: A process for manufacturing carbon membranes having controlled pore sizes comprises the steps of: a) causing a stream of a pyrolysable carbon-containing gas to come into contact with a carbon membrane having a pore size and/or distribution larger than the desired pore size and/or distribution; b) raising the ambient temperature of the said membrane to or above the temperatures at which the adsorbed carbon-containing gas pyrolyzes; and c) substantially purging the atmosphere surrounding the membrane from carbon-containing gas.
