    Abstract: A fuel composition for a spark-ignition internal combustion engine comprises an additive having a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon. The additive increases the octane number of the fuel, thereby improving the auto-ignition characteristics of the fuel.

    Abstract: Methods for preparing an octane-boosting fuel additive having the following formula: are provided. In a first aspect, the method may comprise carrying out the following reaction: (i), (ii) In a second aspect, the method may comprise: (1) preparing the fuel additive; and (2) purifying the product of step (1) by: (a) dissolving the fuel additive in a water-insoluble solvent to form a solution; (b) washing the solution with water; and (c) separating the fuel additive product from the water-insoluble solvent using distillation. Steps (i) and (1) of the methods are carried out in the presence of butylated hydroxytoluene.

    Abstract: An additive composition for use in a fuel for a spark-ignition internal combustion engine comprises an octane-boosting additive and one or more further fuel additives. The octane-boosting additive has a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon. The additive composition increases the octane number of the fuel, thereby proving the auto-ignition characteristics of a fuel.

    Abstract: A method for improving the ferrous corrosion-preventing characteristics of a fuel comprises combining an additive having a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon with the fuel. The additive may also be used for preventing ferrous corrosion in a system which comprises a fuel, such as a fuel system in a vehicle.

    Abstract: The present disclosure concerns embodiments of a catalyst system, such as a mixed catalyst composition, that can be used to make biofuel. In some embodiments, the mixed catalyst composition can comprise an inorganic catalyst and an organic catalyst, such as a cyclic organic catalyst. In particular disclosed embodiments, a mixed catalyst composition comprising, consisting essentially of, or consisting of an inorganic catalyst and an organic catalyst can be used to enhance the production of biofuel, such as biodiesel, by reducing the amount of time needed to make the biofuel as compared to that needed for the inorganic catalyst or the organic catalyst independently. Also disclosed herein are combinations and kits comprising, consisting essentially of, or consisting of embodiments of a mixed catalyst composition.
