Abstract: Provided are octane enhancing additives and methods that improve a liquid fuel composition's octane rating. A liquid fuel composition may comprise a liquid fuel and an octane enhancing additive. The octane enhancing additive may comprise an indoline compound with a bicyclic ring structure, wherein the indoline compound comprises a six-membered aromatic ring and a five-membered aliphatic ring that share a carbon-carbon aromatic bond. The five-membered aliphatic ring may be heterocyclic and may comprise a nitrogen positioned in an alpha position to the six-membered aromatic ring.

Abstract: GDI deposit fluidizing additives, liquid fuel compositions including such additives and methods that improve a liquid fuel composition's GDI performance are provided. A liquid fuel composition may include a major amount of a base gasoline fuel; and 1 to 500 ppm of one or more polyether monohydroxy compounds, with the proviso that the liquid fuel composition is essentially free of fuel detergent additives. The liquid fuel composition provides at least 10% lower particulate emission as a function of time relative to a comparable liquid fuel composition not including the one or more polyether monohydroxy compounds. The GDI deposit fluidizing enhancing additive may include polyether monohydroxy compounds with the butane oxide and propene oxide in a variety of ratios and randomly distributed in the additive.

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.
