The inhibiting effect of dichloroethane on the complete oxidation of ethylene oxide over an Ag/Al2O3 catalyst was studied by the flow-circulation method. The study was carried out under steady-state conditions, at atmospheric pressure and in the temperature range 210–300°C. The inhibitor feed concentration was varied from 1 to 28 ppm. A kinetic model of the reaction is proposed that includes the inhibitor partial pressure in its functional form. It describes adequately the dependence of the conversion on the contact time, feed composition, temperature and inhibitor concentration and also the dependence of the oxidation rate on the outlet partial pressures of oxygen and ethylene oxide. Catalytic decomposition of ethylene oxide is observed at high temperatures and with oxygen shortage.
