Abstract: A method for producing renewable arctic diesel is provided herein. The method includes contacting a bio-derived feedstock with a hydrotreatment catalyst under effective hydrotreatment conditions to produce a hydrotreated feedstock and separating the hydrotreated feedstock into gas phase products and liquid phase products. The liquid phase products include an oxygen content of less than 0.4 wt % but greater than 10 ppm. The method also includes contacting the liquid phase products with a ZSM-48-based isomerization/dewaxing catalyst under effective isomerization/dewaxing conditions to produce an isomerized product stream including a change in cloud point (ΔCP) of 50 degrees ° C. or more. The method further includes separating the isomerized product stream into gas phase products and liquid phase products, as well as fractionating the liquid phase products to produce renewable naphtha and renewable arctic diesel with a cloud point of −20° C. or less and a yield of 80 wt % or more.
