A rotating gliding arc (RGA) reactor was investigated for conversion of multiple model tar compounds including toluene, naphthalene, and phenol in simulated synthetic gas, with special focus on the effects of steam concentration (0–20%) and preheating temperature (300–700 °C). The maximum conversions of toluene, naphthalene, and phenol were 89.3%, 84.6% and 95.5%, respectively, at a steam concentration of 12% and a preheating temperature of 500 °C. The tar conversion reaction facilitated the formation of fuel gas H₂ and CO and reduced the CH₄ and CO₂ content, thus increasing the heating value of the simulated synthetic gas, by a maximum of 5.1% at a steam concentration of 20%. The results indicated that the RGA plasma is promising for achieving efficient conversion of tar of complex composition in high temperature simulated synthetic gas and upgrading gaseous products.

模拟合成气中甲苯，萘和苯酚作为模型焦油化合物的等离子体转化

对旋转滑弧（RGA）反应器进行了研究，以模拟模拟合成气中多种模型焦油化合物（包括甲苯，萘和苯酚）的转化，并特别关注蒸汽浓度（0-20％）和预热温度（300- 700°C）。在12％的蒸汽浓度和500°C的预热温度下，甲苯，萘和苯酚的最大转化率分别为89.3％，84.6％和95.5％。焦油转化反应促进了燃料气体H ₂和CO的形成并减少了CH ₄和CO ₂蒸汽浓度为20％时，模拟合成气的热值最多可增加5.1％。结果表明，RGA等离子体有望在高温模拟合成气中实现复杂成分的焦油的高效转化并提纯气态产物。
