Abstract:
In this research work, ethylene oxide production performance under a low- temperature parallel plate dielectric barrier discharge (DBD) system with two dielectric glass plates and the upper glass plate coated with 0.1 wt.% Ag catalyst calcined at different temperatures was investigated. Under optimum conditions (an applied voltage of 19 kV, an input frequency of 500 Hz, a total feed flow rate of 50 cm3/min, a gap distance of 0.7 cm, and a N2O:C2H4 feed molar ratio of 0.17:1), the highest EO selectivity of 48.9% and the highest EO yield of 8.6% were achieved at a calcination temperature of 550 °C. The use of N2O as oxygen source provided comparatively better ethylene epoxidation performance than O2
