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.
