Frederic Vogel 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).

  • Process for generating methane and/or methane hydrate from biomass
    Patent number: 8475549
    Abstract: To generate methane from biomass, a biomass pulp is produced from the biomass with a desired dry mass content being set, and the biomass pulp is placed under pressure. The biomass pulp is heated under pressure in order to liquefy the solid organic components of the biomass pulp. The pressurized and heated biomass pulp is heated further to at least the critical temperature of the biomass pulp. Solids precipitated under pressure and increased temperature are separated from the fluid phase. At least a part of the remaining fluid phase is gasified under pressure and increased temperature by means of a reactor to form a methane-rich gas.
    Type: Grant
    Filed: June 19, 2006
    Date of Patent: July 2, 2013
    Assignee: Paul Scherrer Institut
    Inventors: Frederic Vogel, Samuel Stucki, Thanh-Binh Truong, Maurice H. Waldner

  • Thermal conversion of biomass to valuable fuels, chemical feedstocks and chemicals
    Publication number: 20020082458
    Abstract: A continuous process for the conversion of biomass to form a chemical feedstock is described. The biomass and an exogenous metal oxide, preferably calcium oxide, or metal oxide precursor are continuously fed into a reaction chamber that is operated at a temperature of at least 1400° C. to form reaction products including metal carbide. The metal oxide or metal oxide precursor is capable of forming a hydrolizable metal carbide. The reaction products are quenched to a temperature of 800° C. or less. The resulting metal carbide is separated from the reaction products or, alternatively, when quenched with water, hydolyzed to provide a recoverable hydrocarbon gas feedstock.
