1. A process for hydroprocessing a sustainable feedstock, the process comprising:
hydrocracking a hydrocracking feed stream comprising greater than 90% paraffins in a hydrocracking reactor in the presence of hydrogen over a hydrocracking catalyst comprising one or more Group VIII metal and/or Group VIB to provide a hydrocracked stream, wherein the hydrocracking reactor is operated at a temperature of about 290° C. (550° F.) to about 450° C. (842° F.) and a pressure of about 2.7 MPa (gauge) (400 psig) to about 20.7 MPa (gauge) (3000 psig);
hydroisomerizing said hydrocracked stream in an hydroisomerization reactor in the presence of hydrogen over a hydroisomerization catalyst to provide a hydroisomerized stream, wherein the hydroisomerization reactor is operated at a temperature of about 290° C. (550° F.) to about 450° C. (842° F.) and a pressure of about 2.7 MPa (gauge) (400 psig) to about 20.7 MPa (gauge) (3000 psig)
separating said hydroisomerized stream into a hydroprocessed vapor stream and a hydroprocessed liquid stream;
stripping said hydroprocessed liquid stream in a stripper to provide a stripper overhead stream and a stripper bottoms liquid stream; and
distilling said stripper bottoms liquid stream to produce a jet fuel range stream.
