摘要：

The deep oxidation of toluene over La0.8Sr0.2CoO3 catalyst in the range of 239-255-degrees-C was investigated by employing a fixed-bed flow reactor. Several kinetic models for the reaction mechanism and the rate expression have been tested. It is found that a Langmuir-Hinshelwood model incorporating a dual-site mechanism with competitive adsorption of atomic oxygen and toluene is suitable for the cases of higher partial pressure of oxygen, lower partial pressure of toluene, and low conversion, but not suitable for the case of high conversion obtained at high temperature. A semiempirical equation is proposed to correlate the data of conversion and reaction temperature.
