Lignin-rich biomass (beech wood, pine bark, and oak bark) and four lignins were tested as precursors to produce activated carbon (AC) via a two-step chemical activation with KOH. First, the precursors were carbonized via either pyrolysis or hydrothermal carbonization, with the purpose of evaluating the influence of the carbonization process on the AC properties.

Abstract Activated carbons (AC) serve as adsorbents in various applications requiring specific functionalities. In this study, the effects of biomass type, pre-carbonization process, and activation method on the properties of ACs were investigated. The preparations of activated carbon are easy and safe processes, mainly from the pyrolysis or gasification of biomass with heat and/or chemicals. The recycling and regeneration of activated carbon after use are also essential for resource maintenance and environmental safety. To effectively investigate the influence of activated carbon on the adsorption of volatile organic compounds (VOCs), physical and chemical factors of activated carbon including pore wall thickness, pore size, and functional groups were studied using grand canonical Monte Carlo (GCMC) simulation. In addition, benzene and acetone were taken as two representative
