Aiming at the current drawbacks of activated carbon materials including poor selective adsorption and narrow application scope, this research takes pine and fir tree residues as raw materials, breaking through common technical bottlenecks such as raw material pretreatment, carbonization, and pore structure control methods in the activation process, focusing on key technologies of catalytic thermoplastic molding and directional activation of lignocellulosic raw materials to develop granular activated carbon products for vehicle fuel volatilization control. It also researches the plasticizing and molding technology of lignocellulosic raw materials based on alkali/urea systems, preparing functional in-situ nitrogen-doped granular activated carbon via physical and chemical activation methods; develops new technologies for controlling the formation of microporous structures in activated carbon through carbon-water reactions to fabricate high-capacity energy storage activated carbon and high-efficiency catalyst carrier carbon; explores novel solvent dissolution-foaming-resinification-activation technologies for lignocellulosic raw materials to produce new high-efficiency mesoporous foamed activated carbon products; and investigates the composite technology of powdered activated carbon and magnetic gels to prepare novel magnetic activated carbon. Finally, by integrating product innovation and process R&D and establishing demonstration production lines, this study achieves key technical research outcomes for dedicated activated carbon with excellent adsorption performance.
