摘要：
This paper investigates the effect of different zeolites on the performance of zeolite supported Pt samples towards the catalytic combustion of chlorobenzene. Pt/zeohte samples showed a higher activity compared to a Pt/Al(2)O(3) sample used as reference. Pt catalysts supported on H-Y and H-beta zeolites was found to be more active than Pt on H-ZSM5 and H-ferrierite. The yield to polychlorinated benzenes (PhCl(x)) was in the order Pt/Al(2)O(3) > Pt/H-beta congruent to Pt/H-Y > Pt/H-ZSM5 > Pt/H-ferrierite. This trend has been explained on the basis of a pore size effect induced by the zeolite which restrains the chlorination of chlorobenzene to PhCl(x).
