Abstract

Abstract:

The preparation of CO₂ adsorbents using industrial solid waste carbide slag is associated with advantages such as low cost，simple process，and excellent adsorption performance.However， carbide slag is prone to sintering at high temperatures，which significantly reduces its CO₂ cyclic adsorption/desorption performance.Therefore，the inhibition of sintering at high temperatures and the improvement of its cyclic adsorption/desorption performance are significant challenges.The various modification of calcium carbide residue methods，including solid-phase disordered doping with metal oxides such as Al₂O₃ and MgO，biomass template doping，organic acid liquid-phase doping，steam reactivation，and inorganic acid reactivation were systematicaly summarized.The modification effects of carbide slag microstructure on CO₂ adsorption/desorption performance were discussed，and the mechanisms behind the effects of different modification methods on the CO₂ adsorption/desorption performance of carbide slag were also revealed.The results indicated that employing solid-phase disorder-doped metal oxides as a skeletal support effectively improved the pore structure and anti-sintering resistance of the adsorbent，with calcium aluminates and MgO exhibiting the most pronounced modification effects.Steam reactivation of carbide slag has been shown to effectively reconstruct the collapsed pore structure inside the adsorbent.Future research should focus on the synergistic effects of multiple modification techniques combined with steam reactivation to further enhance the energy efficiency of the cyclic process，providing a theoretical basis for the performance improvement and industrialization of carbide slag-based CO₂ adsorbents.It holds significant academic value and practical application potential.
