    Influence of Activated Carbon Granulometry on H<sub>2</sub> Purification in Glycerol Reforming Syngas: Adsorption and Kinetic Analysis by Rocio Maceiras, Jorge Feijoo, Leticia Perez-Rial, Miguel A. Alvarez-Feijoo, Naser Eslami

    Published 2024-11-01
    “…Kinetic analysis revealed that the pseudo-second-order and Avrami models fit well with both adsorbents, though GAC aligns more closely with the Avrami model, reflecting its multi-step adsorption mechanism and greater pore diffusion efficiency. These findings highlight the importance of adsorbent size and flow rate in optimizing hydrogen purification processes, with GAC emerging as a highly efficient adsorbent for industrial-scale syngas treatment.…”
