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) removing substantially all of the remainder of the water present by use of vacuum or by passing hot air or hot nitrogen through the activated carbon.
