zone 6 on the basis of the wide cut liquid of about 2 20 wt more preferably about 5 10 wt the hydrocracking reaction is preferably carried out within the hydrocracking zone 6 under typical hydrocracking conditions preferably the hydrocracking zone 6 will operate at a temperature of about 700 u00b0 900 u00b0 f and a residence time of about 5 minutes to 6 hours the hydrogen gas can be molecular hydrogen or a hydrogen donating gas such as hydrogen sulfide and is preferably added to the hydrocracking zone 6 through a line 8 at a hydrogen partial pressure of about 1000 3000 psig the hydrocracked reaction products are removed from the hydrocracking zone 6 and sent to a separation zone 9 for separation into separate component product streams the hydrocracked reaction products comprise some gas as well as low and high boiling point liquid components as a result of the hydrocracking reaction the gas and low boiling point liquids can be separated within the separation zone 9 as desired the separation zone 9 can be operated under flash conditions or under vacuum depending upon the specific composition of the component streams that is desired preferably the gas and liquids which have a boiling point of less than about 350 u00b0 f are removed together as a light ends distillate fraction the liquid portion of the light ends fraction typically includes naphtha if desired a middle distillate stream can also be recovered from the separation zone 9 this middle distillate is preferably a distillate stream having a boiling point of about 350 u00b0 650 u00b0 f such.
