The trace‐O2 removal in coke oven gas, which enables better utilization of its contained H2, is investigated with combinations of atmospheric nonthermal plasma and a Pt/γ‐Al2O3 catalyst. Herein it is shown that a coaxial packed‐bed dielectric barrier discharge (DBD) reactor removes up to 80 % O2 in a model coke oven gas. Along this line, the H2 content and the usage of Al2O3 granules in the plasma zone have been identified as major factors for the plasmachemical trace‐O2 conversion. In contrast to the Pt/γ‐Al2O3 catalyst, nonthermal plasma converts trace O2 at coke oven gas temperatures below 100 °C.

同轴填充床-DBD反应器去除焦炉煤气中的等离子体化学痕量氧

跟踪-O 2除去焦炉煤气中,这使得其所含的H的更好的利用2,进行了研究与大气非热等离子体和Pt /组合γ -Al 2 ö 3催化剂。本文显示,同轴填充床电介质阻挡放电(DBD)反应器可去除模型炼焦炉气体中的80%O 2。沿着这条线,血浆区域中的H 2含量和Al 2 O 3颗粒的使用已被确定为等离子体化学痕量O 2转化的主要因素。与Pt / γ- Al 2 O 3相比作为催化剂,非热等离子体在低于100°C的焦炉煤气温度下将痕量O 2转化。
