摘要: Abstract Different pretreatments (wet, oxidation and complex pretreatments) were used to modify activated carbon honeycomb monolith, the role of surface properties support in CO over Pd/ACHM catalysts was also investigated. Pretreatment an efficient way introduce oxygen groups, especially by pretreatment. Oxygen-containing groups increased 1.7 times as much that original ACHM, 86% conversion obtained at 30 °C 100% relative humidity on supported Pd catalyst prepared from modified ACHM. species not only improved dispersion but affected states. Compared with dispersion, states played a more important oxidation. The amount low-valent (Pd 0 , + 1 ) consistent activity. presence NO caused decrease 15% which attributed difference between adsorption energy surfaces confirmed density functional theory calculation. 90 days' 1000 m 3 /h pilot experiment results showed exhibited high activity stability moisture x .
