METHOD OF IMPROVING THE SELECTIVITY OF CARBON MEMBRANES BY CHEMICAL CARBON VAPOR DEPOSITION |
摘要 |
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.
