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 CO.sub.2, H.sub.2O, and energy. The energy is recycled and utilized in the host plant, and the CO.sub.2 and H.sub.2O 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.

The process includes activating a char in an oven by heating the char with steam to generate activated carbon and syngas. The process also includes monitoring parameters of the syngas produced and controlling the oven in response to the parameter. The process converts a feedstock, typically organic waste, into useable products.

There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.

A method and a device are provided for producing activated carbon in a gasification process. A first process stage includes thermally decomposing a carbonaceous starting material, in particular biomass, in a first reaction zone to produce pyrolysis coke and pyrolysis gas. A second process stage includes generating, from the pyrolysis gas in the second reaction zone, a product gas which can be used for activating the pyrolysis coke. A third process stage includes activating at least a portion of the pyrolysis coke to form activated carbon with the aid of the product gas in the third reaction zone.
