Patents by Inventor Earnest Stuart

Earnest Stuart 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: 10828801
    Abstract: This invention provides a finely ground biomass material used to create biomass-containing plastics having a smooth surface, while also preventing creation of unwanted color including those created by the Maillard reaction which results from a combination of sugars, protein, heat and acid or base chemicals. The present invention also provides for methods to prevent agglomeration of small particles into larger particles which can produce irregular surfaces on biomass-based plastics, including thin film plastics, especially thin film plastics less than 4 mil and other thin film plastics that can become too large to use in thin-film plastic production. For the purpose of this invention, plastic resins can be any gas or liquid hydrocarbon or fermentation-based resins.

  • Patent number: 9284616
    Abstract: The invention is directed to a process for refining biomass to produce hemicellulose hydrolyzates, cellulose of sugars involving the perforate at least a portion of the cells of the prepared biomass prior to hydrolyzing the biomass, reclaiming the catalysts used in hydrolysis for further hydrolysis, and drying the hydrolysis using reclaimed heat from previous steps in the process.

  • Patent number: 8414771
    Abstract: The present invention is a method for refining native biomass to extremely fine and highly disrupted particles using high shear and/or cavitation in combination with high temperature and high or low pH conditions which dissolve biomass to a high percentage. The method of the present invention results in a high percentage of hydrolysis, in many cases near theoretical levels, in short residence times while minimizing inputs over other methods, using low chemical inputs, and optionally with no chemical inputs in certain stages compared to existing processes. The method of the present invention also uses minimal electrical energy inputs and conserves heat energy within the process and reduces equipment requirements while producing concentrated products.

  • Publication number: 20120202252
    Abstract: A method for recycling cellulase enzymes. Also provided is a method for producing fermentable carbohydrates, plant leaf protein, and lignin, by adding a cellulase enzyme complex expressed from and on irradiated cellulase complex-producing organisms with sufficient radiation to kill biological activity without destroying all cellulase enzyme complex activity to biomass. The fermentable carbohydrates produced by the method. Also provided are irradiated cellulase-producing organisms for use in converting biomass to fermentable sugars, plant leaf protein, and lignin. A method for producing cellulase enzymes for glucose and other sugar production and protein and lignin extraction by irradiating cellulase-producing organisms, thereby producing the cellulase enzymes is also provided. A system for producing fermentable carbohydrates, plant protein, and lignin, said system comprising irradiated cellulase-producing organisms and biomass is provided.
