One exemplary embodiment can be a process for desorbing one or more polynuclear aromatics from at least one fraction from a hydrocracking zone using an adsorption zone. The adsorption zone can include first and second vessels. Generally, the process includes passing the at least one fraction from an effluent of the hydrocracking zone through the first vessel containing a first activated carbon, and passing a petroleum fraction boiling in the range of about 200-about 400° C. for desorbing the one or more polynuclear aromatics through the second vessel containing a second activated carbon.
