  • Patent number: 11905482
    Abstract: Fuel briquettes based on carbon-containing materials, such as fuel briquettes for household use for heating of living and housekeeping spaces, glass-covered and film-covered greenhouses, especially in those geographic regions where no natural fuels like firewood, coal or turf are available. The fuel briquettes may also be used in chimney fireplaces, portable stoves, boilers, grills and braziers, for heating of railway carriages and accommodation cabins for labor and military personnel. A new binder, namely, Sosnowsky's hogweed, is used, providing environmental improvement and termination of weed infestation of fertile soils due to expansion of Sosnowsky's hogweed. The technical effects are attained by a fuel briquette containing a premix of ground carbon-containing filler and a biomass of ground plants of Sosnowsky's hogweed (e.g., entire plants including leaves, stems, roots and umbels) used as a binder. The briquette is compressed to remove liquid content and then dried.

  • Patent number: 11891582
    Abstract: This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

  • Patent number: 11866669
    Abstract: A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber are controlled by controlling the moisture in the combustion atmosphere and energy injections at or downstream of the combustion chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy plasma within the combustion chamber environment are controlled to degrade hazardous polyfluoro compounds.

  • Patent number: 11821823
    Abstract: A method and a system for creating a reference standard for hydrogen sulfide concentrations in crude oil are described. The method includes receiving a volume of crude oil in a vessel. A hydrogen sulfide gas is flowed from a pressurized gas cylinder to the vessel to form a hydrogen sulfide gas-crude oil mixture. The hydrogen sulfide gas continues to flow from the pressurized gas cylinder to the vessel at a set pressure for a predetermined time to adjust the hydrogen sulfide concentration in the hydrogen sulfide gas-crude oil mixture to a hydrogen sulfide threshold concentration. The flow of the hydrogen sulfide gas into the vessel is stopped.
