POSSIBILITIES OF PRODUCING ACTIVATED CHARCOAL FROM WOOD WASTE IN PRODUCTION BY PYROLYSIS

Аннотация

This paper explores the technical and economic feasibility of producing high-quality activated carbon from wood industry residues through integrated pyrolysis and activation processes. Woody waste—sawdust, bark, and offcuts—is first converted into biochar via controlled pyrolysis, followed by physical or chemical activation to develop extensive microporous structures. Key process parameters, including pyrolysis temperature, residence time, activating agent, and gas atmosphere, are analyzed for their impact on surface area, pore volume, and adsorption capacity. The resulting activated carbons exhibit Brunauer-Emmett-Teller (BET) surface areas exceeding 900 m²/g and iodine numbers above 1,000 mg/g, suitable for water purification, gas adsorption, and catalyst support. Integration with existing pyrolysis biorefineries enables co-production of bio-oil and syngas, significantly improving overall process economics. This work provides a scientifically grounded framework for transforming low-value wood waste into premium functional materials.
