  • Publication number: 20160326448
    Abstract: Reduced emissions in a jet fuel having aromatics content can be achieved by incorporating a quantity of an aromatic kerosene fuel blending component, preferably a bio-derived synthetic aromatic kerosene, comprising at least 90 wt. % of aromatics, less than 10 wt. % of indanes and tetralins and less than 1 wt. % of naphthalene into a jet fuel in a manner to meet the aromatic content specification for jet fuels. A jet fuel having aromatics content having reduced number-based nvPM emissions compared to equivalent total aromatics content petroleum-derived kerosene jet fuel is obtained.

  • Patent number: 6767372
    Abstract: An aviation gasoline (Avgas) fuel composition possessing a high motor octane number and which contains reduced amounts of tetraethyl lead is disclosed. The Avegas composition preferably comprises about 20 to about 80 vol % iso-octane, about 5 to about 18 vol % toluene, about 1 to about 20 vol % C4 to C5 paraffins, about 0 to about 1 ml/gallon tetraethyl lead (TEL) and the balance light alkylate. The Avgas composition may be economically produced utilizing spare methyl tertiary butyl ether plant capacity to produce iso-octane as one component of the composition.
