The role of N₂ carrier gas toward the conversion of tar analogue (toluene) was studied in a non-thermal plasma dielectric barrier discharge reactor. The parameters investigated were power (5–40 W), residence time (1.43–4.23 s), toluene concentration (20–82 g/Nm³), and wall temperature (from ambient to 400 °C). Almost complete removal (99%) of toluene was observed at 40 W and 4.23 s. The main gaseous product was H₂, with a maximum selectivity of 40%. The other gaseous products were lighter hydrocarbons (LHCs, C₁–C₆, 5.5%). The selectivity to these LHCs could be increased to 10% by increasing the temperature to 400 °C. Introducing H₂ to the N₂ carrier gas at elevated temperatures opened up new reaction routes to enhance the selectivity to LHCs. The selectivity to methane reached 44% at 35% H₂ at 400 °C, and the total selectivity to LHCs reached 57%.

使用非热等离子体介电阻挡层放电反应器去除N ₂载气中的焦油形式的甲苯

在非热等离子体介电势垒放电反应器中研究了N ₂载气对焦油类似物（甲苯）转化的作用。研究的参数是功率（5–40 W），停留时间（1.43–4.23 s），甲苯浓度（20–82 g / Nm ³）和壁温（从环境温度到400°C）。在40 W和4.23 s下观察到甲苯几乎完全去除（99％）。气态主要产物为H ₂，最大选择性为40％。的其它气态产物为较轻的烃（LHCs，C ₁ -C ₆，5.5％）。通过将温度升至400°C，可以将这些LHC的选择性提高至10％。将H ₂引入N ₂高温下的载气开辟了新的反应路线，以提高对LHC的选择性。在400°C下35％H ₂下，甲烷的选择性达到44％，对LHC的总选择性达到57％。
