Abstract:
A study is made of the influence of the pH in the synthesis of the active component on the formation of structure and on the activity of vanadium catalysts. It has been established that the differences in the chemical and phase composition of the original potassium and vanadium compounds that are observed, depending on the pH at which these compounds are obtained, influence the fraction of blocked vanadium, the M/V ratio in the blocked and accessible parts of the active component, and the catalyst activity. This is due to the nonuniform melting of the phases making up the active component with pH 3-5 and the considerable sintering of the support in the stages preceding exposure to the reaction mixture.
