	%X The effects of ethylene (C2H4) feed position and
O2/C2H4 feed molar ratio on ethylene epoxidation in a parallel
dielectric barrier discharge (DBD) were studied. The results showed
that the ethylene feed position fraction of 0.5 and the feed molar
ratio of O2/C2H4 of 0.2:1 gave the highest EO selectivity of 34.3%
and the highest EO yield of 5.28% with low power consumptions of
2.11×10-16 Ws/molecule of ethylene converted and 6.34×10-16
Ws/molecule of EO produced when the DBD system was operated
under the best conditions: an applied voltage of 19 kV, an input
frequency of 500 Hz and a total feed flow rate of 50 cm3/min. The
separate ethylene feed system provided much higher epoxidation
activity as compared to the mixed feed system which gave EO
selectivity of 15.5%, EO yield of 2.1% and the power consumption of
EO produced of 7.7×10-16 Ws/molecule.
