ABSTRACT:
Fused polynuclear aromatic compounds (PNAs) are continuously removed from a recycle oil stream in a hydrocracking process. An adsorption bed removes the PNAs from the recycle oil, a desorbing reagent removes the PNAs from the bed, and a regenerating agent regenerates the bed, all steps being performed simultaneously and continuously.
