Patents by Inventor Mitch Loescher

Mitch Loescher 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).

  • Method of thermolyzing biomass in presence of hydrogen sulfide
    Patent number: 9644150
    Abstract: The amount of renewable hydrocarbons produced from biomass may be increased by pyrolyzing the biomass in a biomass conversion unit in the presence of hydrogen sulfide or a sulfiding agent. The formation of deposits of unwanted carbonaceous materials, such as coke, is reduced by the presence of the hydrogen sulfide or sulfiding agent.
    Type: Grant

    Date of Patent: May 9, 2017
    Assignee: Inaeris Technologies, LLC
    Inventors: Lorenz J. Bauer, Mitch Loescher

  • Apparatus for producing organic acids
    Patent number: 5962307
    Abstract: A continuous process and apparatus for preparing organic acids and their salts from biomass. Biomass flows from a region of fresh biomass and high acid and acid salt concentration to a region of digested biomass and low acid and acid salt concentration in a fermentation apparatus under anaerobic conditions. Organic acids and acid salts produced by the process of the present invention are volatile fatty acids such as acetic, butyric and propionic acids and their salts such as calcium acetate, calcium propionate, and calcium butyrate. The apparatus of the present invention contains at least two fermentation reactors in series to increase the biomass residence time in the reactors. The fermentation reactors of the present invention are imbedded in the ground with earthen berms as support for sides having three layers. The core of the reactors are covered with a flexible covering to maintain an anaerobic environment.
