This patent describes a catalytic hydrocracking process. It includes contacting a hydrocarbonaceous feedstock having a propensity to form 11{sup +} ring heavy polynuclear aromatic compounds and a liquid recycle stream in a hydrocracking zone with added hydrogen and a metal promoted hydrocracking catalyst at elevated temperature and pressure sufficient to gain a substantial conversion to lower boiling products; partially condensing the hydrocarbon effluent from the hydrocracking zone and separating the same into a hydrocarbonaceous stream comprising lower boiling hydrocarbons, unconverted hydrocarbons boiling above about 400{degrees} F (204{degrees} C) and trace quantities of 11{sup +} ring heavy polynuclear aromatic compounds, and a vaporous hydrocarbonaceous stream comprising the lower boiling hydrocarbons.
