"HYDROCRACKING PROCESS" ABSTRACT A method is disclosed for hydrocracking a hydrocarbon feedstock having a propensity to form polynuclear aromatic compounds without excessively fouling the processing unit. The hydrocracking method includes contacting the hydrocarbon feedstock with a crystalline zeolite hydrocracking catalyst, contacting at least a portion of the resulting unconverted hydrocarbon oil containing polynuclear aromatic compounds with an adsorbent which selectively retains polynuclear aromatic compounds and recycling unconverted hydrocarbon oil having a reduced concentration of polynuclear aromatic compounds to the hydrocracking zone.
