Abstract
A multiple single-stage process for the conversion of heavy hydrocarbonaceous charge stock into a lower boiling distillate hydrocarbon product. Fresh charge stock and hydrogen are introduced into a first catalytic reaction zone for substantially 100% conversion of the feed. Hydrocracked product effluent from the first hydrocracking reaction zone which comprises a predetermined distillate fraction is passed with an accucracked effluent from a second catalytic hydrocracking or accucracking reaction zone into a separation zone and separated into various hydrocarbon streams including a light hydrocarbon stream comprising the distillate product, a middle hydrocarbon stream and a heavy hydrocarbon stream. The middle hydrocarbon stream comprising said distillate fraction and hydrogen is introduced into the second catalytic hydrocracking or accucracking reaction zone for conversion into a lower boiling accucracked effluent stream comprising the distillate hydrocarbons boiling in the distillate product range. The accucracked effluent is admixed with the hydrocracked effluent as described above.
