A method and apparatus for producing activated carbon from biomass or other solid carbonaceous feed within a housing containing boiler components, by spatial separation of drying, pyrolysis and activation zones as the feed is conveyed across the bottom of the housing, such that the thermal requirements for drying, pyrolysis, and activation of the solid carbonaceous feed occur by direct radiation from the combustion flame located above the drying, pyrolysis and activation zones. The balance of the heat not required for drying, pyrolysis, and activation is used to vaporize and superheat steam as part of a conventional steam/electric power plant.

A system and method for producing a coal product from a carbon source material. The coal product may include a green carbon foam, a finished carbon foam, and/or a coal siding product. The system and method for producing a green carbon foam may involve pulverizing the carbon source material prior to processing the pulverized carbon source material to produce the green carbon foam using a float bath or an extruder. During production of the green carbon foam, the temperature of the float bath or extruder may be maintained at a temperature determined relative to the Gieseler fluidity properties of the carbon source material used.

Biogenic activated carbon compositions disclosed herein comprise at least 55 wt % carbon, some of which may be present as graphene, and have high surface areas, such as Iodine Numbers of greater than 2000. Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon. Methods of using the biogenic activated carbon are disclosed.

A bio-product such as biochar, bio-coal, bio-oil, coke, and/or activated carbon material is formed by processing a starting biomass material comprising water-laden material. The starting biomass material is heated to below or above an autoignition temperature through a rotary compression unit (RCU) by generating steam through releasing unbound and bound waters in the biomass thus forming a bio-product. The biomass material being processed may be, without limitation, a woody or non-woody biomass material, such as cellulosic material and/or grain. The process can also form bio-oil from pyrolysis vapors which can be processed to other bio-products.
