The deep oxidation of chlorobenzene was investigated over Pt/H-ferrierite and Pt/H-ZSM5 catalysts. Catalytic results showed that Pt/zeolite samples exhibit higher activity and lower by-products formation than Pt/gamma-Al(2)O(3), tested for comparison. Pt/H-ferrierite resulted to be the most favorable system as it leads to the lowest formation of noxious polychlorinated benzenes. The present FT-IR investigation pointed out that the support significantly affects the combustion of chlorobenzene over Pt/zeolite catalysts, support acidity directing the activity of the system and pore structure of the zeolite determining the level and the distribution of polychlorinated compounds.

Abstract
The deep oxidation of chlorobenzene was investigated over Pt/H-ferrierite and Pt/H-ZSM5 catalysts. Catalytic results showed that Pt/zeolite samples exhibit higher activity and lower by-products formation than Pt/gamma-Al(2)O(3), tested for comparison. Pt/H-ferrierite resulted to be the most favorable system as it leads to the lowest formation of noxious polychlorinated benzenes. The present FT-IR investigation pointed out that the support significantly affects the combustion of chlorobenzene over Pt/zeolite catalysts, support acidity directing the activity of the system and pore structure of the zeolite determining the level and the distribution of polychlorinated compounds.| File | Dimensione | Formato | |
