Abstract
One exemplary embodiment can be a process for removing one or more polynuclear aromatics from at least one reformate stream from a reforming zone. The PNAs may be removed using an adsorption zone. The adsorption zone can include first and second vessels. Generally, the process includes passing the at least a portion of an effluent of the reforming zone through the first vessel containing a first activated carbon. The adsorption zone is operated at a temperature of at least 370° C.
