摘要：

The kinetics of complete catalytic oxidation of benzene by ozone on MnO2 in gradientless conditions has been investigated. It was established that the decomposition of ozone and the oxidation of benzene on MnO2 proceed within the same temperature range (10-80-degrees-C), and the apparent activation energies are 32 kJ/mol and 30 kJ/mol, respectively. The complete oxidation of benzene by molecular oxygen takes place at temperatures above 160-degrees-C with an apparent activation energy of 88 kJ/mol. It has been Assumed that the rate-determining step of complete oxidation by ozone is the ozone decomposition.
