文摘

Hydrodechlorination of 4-CP by developed Pd/resin catalysts was mainly dependent on solution pH and adsorption affinity of the resins. Rate determining step for the hydrodechlorination changed from adsorption at low concentrations to surface reaction at high concentrations. Neutral resins were more resistant to the poising effect of Cl− than ionic resins. Adsorption of phenol over multiple reaction cycles resulted in the activity loss.
