Abstract: The deep oxidation kinetics of toluene over PtINM and Pd/NM catalysts was studied in the presence of large excess of oxygen. The catalytic activity of Pt/NM was higher than that of Pd/NM. The rate of the catalytic oxydation could be described by equation The aparent activation energy(△E) and the heat of absorption(Q) of toluene on the catalyst surface were calculated as 49.9(kJ/mol),-29.6(kJ/mol)for Pt/NM and 94.2(kJ/mol),-19.1(kJ/mol)for Pd/NM respectively.

Key words: toluene, oxydation kinetics, Pt, Pd
