Effective carbon monoxide (CO) removal methods are essential for hydrogen (H₂) purification processes to support economically feasible hydrogen energy systems. This study introduces a novel structured sorbent designed for the selective removal of CO from hydrogen-rich gas streams. The sorbents exhibit significantly improved dynamic adsorption performance, increased adsorption capacity, and stable cyclic performance under various operating conditions. Enhanced metal dispersion within these structured sorbents results in superior metal utilization compared to traditional powdered sorbents. Detailed characterization further reveals unique active metal sites influenced by the support environment. The results demonstrate a promising approach for adsorption-based CO removal, potentially advancing high-purity hydrogen production technologies.
