Abstract
A method of removing water from activated carbon is disclosed. Briefly, the method comprises (a) passing liquid 1,2-dichloroethane through a bed of activated carbon until a bulk water phase ceases to exit the bed or until from about 60 to about 80 weight percent of the water present in a water-saturated bed has been removed and (b) passing vapor phase 1,2-dichloroethane through the bed of activated carbon to remove substantially all of the remaining water.
Claims10
A method of removing water from activated carbon wherein the method comprises:
- (a) passing about 0.2 to about 4 bed weights of liquid 1,2-dichloroethane through a bed of activated carbon, which contains from about 0.1 to about 70 weight percent water, until a bulk water phase ceases to exit the bed or until from about 60 to about 80 weight percent of the water present in a water-saturated bed has been removed, and
- (b) passing vapor phase 1,2-dichloroethane through the bed of activated carbon to remove substantially all of the remaining water.
A method of removing water from activated carbon wherein the method comprises:
- (a) passing about 1.4 bed weights of liquid 1,2-dichloroethane, which is at a temperature of 25.degree. C., through a bed of activated carbon whereby from about 60 to about 80 weight percent of the water present has been removed, and
- (b) passing about 6 bed weights of vapor phase 1,2-dichloroethane through the bed of activated carbon to remove substantially all of the remaining water.
