  • Patent number: 11365364
    Abstract: A fuel formulation having a derived cetane number of at least 35 includes a petroleum fraction and a polyoxymethylene dimethyl ether (OMEx) oligomer mix. The petroleum fraction includes a naphtha fraction with a boiling point in the range from 30° C. to 178° C. The polyoxymethylene dimethyl ether oligomer mix has the general formula H3CO—(CH2O)n—CH3 in which n is between 2 and 7, inclusive. A related method for reducing emissions in a compression-ignited engine includes preparing the fuel formulation having a derived cetane number of at least 35 and combusting the fuel formulation in the compression-ignited engine in place of a diesel fuel, thereby reducing emission of at least one of NOx, CO2, or particulates from the compression-ignited engine.

  • Patent number: 10344235
    Abstract: Alternative gasoline, diesel fuel, marine diesel fuel, jet fuel, and flexible fuel compositions are disclosed. The compositions include an alcohol and/or a glycerol ether or mixture of glycerol ethers, which can be derived from renewable resources. When combined with gasoline/ethanol blends, glycerol ethers can reduce the vapor pressure of ethanol and increase fuel economy. Added to diesel fuel/alcohol blends, glycerol ethers improve the cetane value of the blends. In jet fuel, glycerol ethers can replace all or part of conventional deicing additives, lowering skin toxicity, and glycerol ethers ability to reduce particulate emissions can lower the appearance of contrails. Used in marine diesel, the reduction in particulate emissions can be environmentally significant. In another embodiment, the alternative compositions comprise gasoline, ethanol, and n-butanol, and in one aspect, the ethanol and/or n-butanol can be derived from renewable resources.

  • Publication number: 20070234637
    Abstract: A fuel for use in a jet engine may be prepared by admixing a hydrocarbon fuel and a first additive selected from the group consisting of ethoxylated alkylphenol formaldehyde resins, maleic anhydride alpha olefin copolymers and mixtures thereof and a second additive comprising an admixture of platinum group and cerium compounds. The jet fuels including the additives may be used in jet engines where it is desirable to have reduced concentrations of particulates in exhausts, particularly when the jet engines are running at cruise speed.
