Abstract: This application relates to production of renewable fuels, including a method of producing renewable fuels. The method comprises hydrotreating a biofeedstock by contacting reactants comprising a combined feedstock and hydrogen with a hydrotreating catalyst to produce normal paraffins. The combined feedstock comprises a biofeedstock and an additional feedstock. The biofeedstock has about 10% or more of each of metals, phosphorous, and chlorophyll than the additional feedstock. The biofeedstock comprises the metals in an amount of about 300 parts per million (“ppm”) or less, the phosphorous in an amount of about 300 ppm or less, and the chlorophyll in an amount of about 50 ppm or less. The method further comprises isomerizing at least a portion of the normal paraffins to produce branched paraffins in an isomerization effluent.
