Herein disclosed are apparatus and associated methods related to producing an enhanced surface area biochar product with a desired activation level based on receiving biochar into a processing vessel configured with multiple independently temperature-controlled chambers and counter-flow steam injection, controlling activation levels of the biochar by moving the biochar through the processing vessel and adjusting the temperature of the biochar by injecting steam into at least one temperature-controlled chamber of the processing vessel, recovering volatiles driven off through dehydration using a thermal oxidizer, cooling the biochar to a desired discharge temperature using steam and retention time, and discharging the activated biochar product. The processing vessel may be a calciner, a rotary calciner, or a kiln. Biochar may be heated or cooled to a desired thermochemical processing temperature depending on the temperature of the received biochar. Counter-flow saturated steam may sweep volatile gases to a thermal oxidizer using a vacuum system.

The embodiments herein provide a method for producing activated carbonaceous balls. The method includes a step of crushing and sizing raw coconut shells to form coconut shell granules having a diameter of about 0.02 mm-2.36 mm, preferably 0.075 mm-1.18 mm. The method includes a step of mixing pure water to a food grade powder appropriately and boiling it slowly at 15° C.-80° C. to obtain a water-food grade powder mixture. The method includes a step of adding the water-food grade powder mixture 20-40% by weight to the coconut shell granules 100% by weight to obtain a slurry in a pourability condition. The method includes a step of pouring the slurry into a pill making machine equipped with a mold of 3 mm, 5 mm, and 8 mm in diameters selectively to produce the spherical carbon tablets. The method includes a step of drying the spherical carbon tablets and carbonizing the spherical carbon tablets to obtain the activated carbonaceous balls.

The present disclosure relates to a carbon-based porous material microscopically exhibiting a three-dimensional cross-linked net-like hierarchical pore structures with micropores nested in mesopores that are in turn nested in macropores. Such material provides for accelerated adsorption and desorption rates and lower desorption temperatures for recovery of organic gas molecules.
