  • Starch as a fuel or fuel component
    Patent number: 7815695
    Abstract: New fuels and fuel components comprising starch are provided, as well as novel methods for operating a combustor such as a boiler or an internal combustion engine by feeding a starch fuel to the combustor.
    Type: Grant
    Filed: October 2, 2007
    Date of Patent: October 19, 2010
    Assignee: LenLo Chem, Inc.
    Inventor: Leonard T. Lewis
  • Hydrophobic starch having near-neutral dry product pH
    Patent number: 7799909
    Abstract: A free-flowing, hydrophobic starch composition has a near-neutral dry product pH. Methods for making the hydrophobic starch composition by preparing an aqueous mixture comprising a starch, a siliconate, and an acid, where the aqueous mixture has a near-neutral pH, and drying the starch solids to obtain a hydrophobic starch. Novel fuel compositions comprise hydrophobic starch which can be used in internal combustion engines, such as diesel engines. Hydrophobic starch compositions may be used as fuels or fuel components. Novel methods of fueling and operating internal combustion engines use hydrophobic starch as fuel or fuel components.
