ABSTRACT:
A method for drying a catalytic absorbent involves the contacting of a drying fluid with the wet absorbent until the absorbent is reduced to a desired level of water content. Prior to startup of a process employing a catalytic absorbent to remove impurities from a liquid hydrocarbon, water is removed from the absorbent by contact with the liquid hydrocarbon.
