THE SILVER CATALYZED OXIDATION OF ETHYLENE: II. KINETICS OF C2H4 OXIDATION

Abstract

A flow-type apparatus is described and results given for the investigation of the kinetics of the silver catalyzed oxidation of C2H4 by oxygen. Using N2 as diluent, the concentrations of both O2 and C2H4 were varied independently from 9.9 to 79.0% and 2.35 to 9.40% respectively, whilst maintaining a total pressure of 1 atmosphere. Flow rates were varied to give a range of contact times varying from 0.05 to 1 sec. Measurements were made at 234 °C and 274 °C and the data used to estimate initial reaction velocities for both EtO and CO2 formation as a function of O2 and C2H4 partial pressures. These rates were fitted successfully to equations deduced theoretically in Part IV of the present series.
