  • Patent number: 11325834
    Abstract: A process for the conversion of hardwood and bamboo to engineered carbon is disclosed. The biomass feedstock of hardwood and bamboo is placed into a holding canister, and the holding canister is lowered into the sealable reactor vessel. The biomass feedstock is ignited, and superheated stream and/or water is metered, or alternately steam is created in situ by introduction of water, into the process. The process is controlled by supplying compressed air and steam, or in situ water, and releasing process gases. The process is performed in an oxygen deprived state. Steam, or in situ water, is injected at the end of the cycle to end the thermal conversion and clean the resulting engineered carbon.
