Claim Text:
1. A liquid-full process for hydroprocessing a middle distillate fuel feedstock, comprising: (a) contacting the feedstock with (i) a diluent and (ii) hydrogen, to produce a feedstock/diluent/hydrogen mixture, wherein the hydrogen is dissolved in the mixture to provide a liquid feed; (b) contacting the feedstock/diluent/hydrogen mixture with a hydrotreating catalyst in a first reaction zone, to produce a first product effluent; and (c) contacting the first product effluent with a dewaxing catalyst in a second reaction zone, to produce a second product effluent comprising naphtha and a middle distillate product; wherein the middle distillate product has at least one improved cold flow property compared to the middle distillate fuel feedstock and has the yield of at least 85 wt %, and wherein the middle distillate fuel feedstock has a nitrogen content of at least 200 wppm, and the middle distillate product has an iso- to n-paraffin ratio increase of at least 1.5 compared to the middle distillate fuel feedstock.
