William L. Roberts, IV has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8350102
    Abstract: The present disclosure is directed to processes for the direct conversion of lipidic biomass fuelstock to combustible fuels. In particular, the disclosure provides a process for the direct conversion of animal fats to transportations fuels suitable as replacement for petroleum-derived transportation fuels. In an example, the method comprises the steps of hydrolyzing a lipidic biomass to form free fatty acids, catalytically deoxygenating the free fatty acids to form n-alkanes, and reforming at least a portion of the n-alkanes into a mixture of compounds in the correct chain length, conformations, and ratio to be useful transportation fuels. Particularly, the product prepared comprises mixtures of hydrocarbon compounds selected from the group consisting of n-alkanes, isoalkanes, aromatics, cycloalkanes, and combinations thereof.
    Type: Grant
    Filed: October 4, 2010
    Date of Patent: January 8, 2013
    Assignee: North Carolina State University
    Inventors: William L. Roberts, IV, H. Henry Lamb, Larry F. Stikeleather, Timothy L. Turner

  • Patent number: 7816570
    Abstract: A process for the direct conversion of lipid biomass fuel stock to combustible fuels include the steps of hydrolyzing a lipid biomass to form free fatty acids, catalytically deoxygenating the free fatty acids to from n-alkanes, and reforming at least a portion of the n-alkanes into a mixture of compounds having the correct chain length, conformations and ratio to be useful as transportation fuels. The process exhibits an overall energy efficiency of at least about 75%, wherein energy efficiency is calculated as the lower heating value of the produced transportation fuel over the sum of the lower heating value of the process reactants and the total energy input into the process.
