Zusammenfassung:	The present disclosure relates to biofuels, and more particularly, to biomass-based kerosene and aviation turbine fuels. In an aspect, a method is disclosed for producing a light paraffinic kerosene (LPK) where the method includes hydrotreating a biorenewable feedstock to yield a heavy hydrotreater fraction comprising C14-C24 n-paraffins; hydroisomerizing and hydrocracking the heavy hydrotreater fraction with a hydroisomerization catalyst under conditions yielding a hydroisomerizer product that includes a heavy hydroisomerizer fraction and the LPK; and separating the LPK from the hydroisomerizer product. The LPK provided by the method has an existent gum value of 7 mg/100 mL or less as measured according to IP 540 air evaporation method and further includes (a) a weight ratio of isoparaffins to n-paraffins of about 2:1 or greater, or (b) no detectable hydrocarbons with 14 or more carbon atoms as measured by gas chromatography, or (c) a weight ratio of isoparaffins to n-paraffins of about 2:1 or greater and no detectable hydrocarbons with 14 or more carbon atoms as measured by gas chromatography.
