Abstract: A method for the production of a carbon material entirely from raw biomass feedstock for use in connection with a metallurgical production and refining process such as the production of steel, aluminum or silicon. The carbon material has a carbon content of greater than 50% by volume of non-volatile, high purity fixed elemental carbon and includes physical properties such as coking strength, conductivity, density, porosity, surface area and particle size which may be individually modified to meet the requirements of a specific metallurgical application.
Abstract: A method for the production of a carbon material entirely from raw biomass feedstock for use as a reinforcing agent, a filler or a pigment in rubbers and plastics and as a replacement for carbon black. The carbon material has a carbon content of greater than 50% by volume of non-volatile, high purity fixed elemental carbon, is free of environmentally hazardous chemical compounds and components surface area, and includes specific properties, such as density, hardness, or chemical composition to provide superior properties as a reinforcing agent.
Abstract: A method for the production of a carbon black entirely from raw biomass feedstock by pyrolytically decomposing the biomass feedstock in a controlled processing atmosphere at a preselected temperature for a preselected period of time to produce solid carbon material and wood gas, and using the wood gas as a fuel to pyrolyze added oils in a carbon black furnace to produce carbon black and gaseous by-products for processing the biomass feedstock. The carbon material has a carbon content of greater than 90% by volume of non-volatile, high purity fixed elemental carbon, is free of environmentally hazardous chemical compounds and components surface area, and includes specific properties, such as density, hardness, or chemical composition to provide superior properties in diverse applications.
Abstract: The invention provides scalable, modular, mobile systems and methods for the continuous on-site production of carbonaceous pyrolysis by-products having physical properties which may be tailored for specific market requirements. The system includes at least on scalable modular unit having a primary reaction chamber, an input aperture for introducing biomass feedstock and atmosphere into the reaction chamber, an external heat source for initiating an exothermic pyrolysis reaction therein, an internal mechanism for controllably agitating the feedstock, atmosphere and pyrolysis by-products to sustain the reaction at a preselected operating temperature range, and an apparatus for removing the by-products from the systems.
