Abstract: Methods are provided for treatment of kerosene/jet fuel boiling range fractions, such as previously qualified jet fuel fractions, to allow blending of the kerosene/jet fuel boiling range fractions to produce a jet fuel boiling range blend having a breakpoint that is equal to or greater than the breakpoint of at least one of the kerosene jet fuel boiling range fractions used to form the blend. The breakpoint of the jet fuel boiling range blend can be maintained by treating at least one of the component fractions of the blend and/or by treating the blend to reduce a nitrogen content. The reduced nitrogen content can correspond to a reduced content of total nitrogen and/or a reduced content of unexpected nitrogen compounds.
