The thermal and electric behavior of the "K-V" and "K-Na-V" catalyst series for SO2 oxidation has been studied in the working state by means of gas-flow differential thermal analysis (DTA)
thermogravimetric analysis (TGA)and electric conductivity analysis (ECA). Changes in catalyst composition and characterization of catalyst distribution for different kinds of samples have been studied by means of X-ray diffraction(XRD) and scanning electron microscopy (SEM). From changes in catalyst behavior
as observed in different experiments
the reaction mechanism designated as "double temperature range
double vanadium complex and two step" is presented. The simplest model of the mechanism is
