Patents by Inventor Weiran Yang

Weiran Yang 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).

  • One-step catalytic conversion of biomass-derived carbohydrates to liquid fuels
    Patent number: 8674150
    Abstract: The invention relates to a method for manufacture of hydrocarbon fuels and oxygenated hydrocarbon fuels such as alkyl substituted tetrahydrofurans such as 2,5-dimethyltetrahydrofuran, 2-methyltetrahydrofuran, 5-methylfurfural and mixtures thereof. The method generally entails forming a mixture of reactants that includes carbonaceous material, water, a metal catalyst and an acid reacting that mixture in the presence of hydrogen. The reaction is performed at a temperature and for a time sufficient to produce a furan type hydrocarbon fuel. The process may be adapted to provide continuous manufacture of hydrocarbon fuels such as a furan type fuel.
    Type: Grant
    Filed: January 11, 2011
    Date of Patent: March 18, 2014
    Assignee: Penn State Research Foundation
    Inventors: Ayusman Sen, Weiran Yang
