A hydrocracking process employing a hydrocracking catalyst based on zeolite beta together with a metal hydrogenation/dehydrogenation component recycles the unconverted, hydrocracked bottoms fraction to the hydrocracking step for improvements in distillate selectivity and denitrogenation without loss of catalyst activity while improving dewaxing of the unconverted bottoms fraction. The process typically operates at low to moderate hydrogen pressures up to 1500 psig (10445 kPa) with low hydrogen consumptions typically below 800 SCF/Bbl (142 n.l.l..sup.-1). Denitrogenation is notably high at 90 weight percent or higher.
