Abstract

The catalytic activity of supported V2O5-alkalimetal sulfate catalysts was studied by oxidizing toluene and methanol to aldehydes and water. An isothermal, fixed-bed reactor, operating at atmospheric pressure and temperatures of 320, 345, and 370°C, was used to obtain the reaction rate data for different partial pressure combinations of the reaction components of these two systems. Three different approaches, Langmuir-Hinshelwood, Hinshelwood, and two-step redox mechanisms, have been used to study the kinetics, with statistical data interpretation.
