Carbon micro-plant

摘要

The present disclosure provides biorefining systems for co-producing activated carbon along with primary products. A host plant converts a feedstock comprising biomass into primary products and carbon-containing co-products; a modular reactor system pyrolyzes and activates the co-products, to generate activated carbon and pyrolysis off-gas; and an oxidation unit oxidizes the pyrolysis off-gas, generating CO2, H2O, and energy. The energy is recycled and utilized in the host plant, and the CO2 and H2O may be recycled to the reactor system as an activation agent. The host plant may be a saw mill, a pulp and paper plant, a corn wet or dry mill, a sugar production facility, or a food or beverage plant, for example. In some embodiments, the activated carbon is utilized at the host plant to purify one or more primary products, to purify water, to treat a liquid waste stream, and/or to treat a vapor waste stream.

主权项

1. A biorefining system for co-producing activated carbon along with primary products, said system comprising:
a host plant configured to convert a feedstock comprising biomass into one or more primary products and one or more co-products containing carbon; a reactor system configured to pyrolyze and activate said one or more co-products, to generate activated carbon and pyrolysis off-gas; and an oxidation unit configured to oxidize said pyrolysis off-gas, to generate CO2, H2O, and energy, wherein at least some of said energy is recycled and utilized in said host plant; and wherein at least some of said CO2 and/or H2O is recycled and utilized in said reactor system as an activation agent.
