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 490โ620 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^โ1^s^
A new method for preparing supported silver catalysts with a narrow particle size distribution has been developed. For crystals with a diameter ranging from 100 to 1000 ,~ the dependencies of reaction rates on size have been studied for epoxidation and deep oxidation of ethylene. For particles 300-5
