  • Patent number: 10927318
    Abstract: Oxidized disulfide oil (ODSO) compounds, derived from by-product disulfide oil (DSO) compounds from the MEROX process, are effective as lubricity additives for transportation fuels. Significant increases in lubricity of ultra-low sulfur fuels as measured by the WSD test were observed with addition of ODSO compounds in the range of from 0.1 ppmw to 10 ppmw. This use of ODSO compounds as lubricity additives converts an otherwise DSO waste oil product into a valuable commodity that has utility in improving lubricity properties of transportation fuels.

  • Patent number: 10913914
    Abstract: A lubricant includes carbon particles in a carrier. The carbon particles may be nearly spherical, individually have maximum and minimum diameters that differ by no more than ten nanometers, and the maximum diameters of the carbon particles are less than one micrometer. The lubricant may be manufactured by preparing the carbon particles by ultrasound-assisted polymerization of resorcinol and formaldehyde in an aqueous system followed by a heat treatment in an inert or non-oxidizing atmosphere and dispersion of the carbon particles in the liquid hydrocarbon carrier to form the lubricant. Optionally, inorganic metals, alloys, or oxides are coated on the surface of the carbon particles via an additional thermolysis step.
