摘要：

The trace-O(2)removal in coke oven gas, which enables better utilization of its contained H-2, is investigated with combinations of atmospheric nonthermal plasma and a Pt/gamma-Al(2)O(3)catalyst. Herein it is shown that a coaxial packed-bed dielectric barrier discharge (DBD) reactor removes up to 80 % O(2)in a model coke oven gas. Along this line, the H(2)content and the usage of Al(2)O(3)granules in the plasma zone have been identified as major factors for the plasmachemical trace-O(2)conversion. In contrast to the Pt/gamma-Al(2)O(3)catalyst, nonthermal plasma converts trace O(2)at coke oven gas temperatures below 100 degrees C.
