摘要：
A process for hydrocracking a hydrocarbon feedstock having a propensity to form polynuclear aromatic hydrocarbon compounds to suppress 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 iron catalyst in the presence of hydrogen to hydrogenate and hydrocrack the polynuclear aromatic hydrocarbon compounds, and recycling unconverted hydrocarbon oil having a reduced concentration of polynuclear aromatic compounds to the hydrocracking zone.
