ABSTRACT:
A hydrocracking process with improved distillate selectivity is operated at limited conversion without liquid/gas separation between the denitrogenation and hydrocracking catalyst beds or liquid recycle. Conversion is held to a maximum of 50 volume percent to lower boiling products. Relatively mild conditions, especially of pressure, may be employed.
