Ethylene oxidation was carried out on a commercial supported silver catalyst (Ag/or-&O,) in a spinning-basket catalytic reactor. The progress of the reacting system from initial start-up to final steady state, under certain operating conditions, revealed a complex oscillatory dynamic behaviour. The
## Abstract The kinetics of ethylene oxidation by air over a supported silver catalyst were investigated in the temperature range 490β620 K. The reaction network was found to be triangular. Under virtually constant oxygen partial pressure (0.2 bar), the following rate relationships, (in mol g^β1^s^
