Oxidation of acrolein to acrylic acid on vanadium molybdenum oxide catalyst; The reaction kinetics

Abstract

The oxidation kinetics of acrolein have been studied in gas phase in the presence of vanadium molybdenum oxide catalyst. Using a through-flow apparatus with integral reactor, the effect has been studied of concentration of individual reaction components, i.e. acrolein, oxygen, steam and acrylic acid, on conversion degree of acrolein. The measurements have been carried out at atmospheric pressure. For evaluation of the kinetic data measured an equation has been suggested expressing dependence of the oxidation rate on the mentioned parameters.
