Claim 0:
1. A process for hydroprocessing two feed streams comprising:
hydrodeoxygenating a biorenewable feed stream in the presence of hydrogen and a hydrodeoxygenation catalyst to produce a hydrodeoxygenated stream, wherein said biorenewable feed stream comprises at least 30 wt % free fatty acids having 12 and 14 carbon atoms;
hydrotreating a second feed stream comprising free fatty acids in the presence of hydrogen and a hydrotreating catalyst to provide a hydrotreated stream, wherein said second feed stream comprises less than 30 wt % free fatty acids having 12 and 14 carbon atoms;
operating the hydrotreating step at a greater hydrodeoxygenation ratio than the hydrodeoxygenation step, wherein the hydrodeoxygenation ratio is the proportion of mass flow rate of normal paraffins with even carbon number to mass flow rate of normal paraffins in hydrodeoxygenation reaction product;
fractionating the hydrodeoxygenated stream to provide a light normal paraffin stream and a heavy normal paraffin stream; and
mixing a portion of the hydrotreated stream with the light normal paraffin stream or the heavy normal paraffin stream.
