在新型直流旋转滑动弧(RGA)等离子体反应器中进行了甲醇裂解制氢的实验研究。考察了进料流量、外加电压、甲醇浓度、操作电流、预热温度、加水量等重要参数对等离子体甲醇分解反应性能的影响。结果表明，随着外加电压和操作电流的增大，甲醇的转化率显著提高，而进料流量、甲醇浓度和加水量的增加对甲醇的转化率影响不大。气体产物(主要是H2和CO)的选择性与比能量输入呈正相关。对使用不同非热等离子体(例如，介质阻挡放电和电晕放电)的甲醇分解过程的比较清楚地表明，RGA等离子体提供了显著更高的CH3OH转化率(28.6-95.6%)和相对较高的能量产率H2(8.5-32.0g kW−1 h−1)，同时保持了比其他等离子体高几个数量级的处理能力。建立了预测甲醇转化率和氢气能量产率的数学模型。模型敏感性分析表明，甲醇浓度对反应性能的影响最大，而水的加入量对反应性能的影响最小。
Hydrogen production from methanol decomposition was performed in a novel direct current (DC) rotating gliding arc (RGA) plasma reactor. The effects of various important parameters (feed flow rate, applied voltage, CH3OH concentration, operating current, preheating temperature, and water addition) on the reaction performance of the plasma methanol decomposition were investigated. The results showed that increasing the applied voltage and the operating current remarkably enhanced the CH3OH conversion in contrast to the effects of increasing feed flow rate, CH3OH concentration, and water addition. The selectivities of gas products (primarily H2 and CO) appeared to be positively correlated with the specific energy input. A comparison of the methanol decomposition processes using different non-thermal plasmas (e.g., dielectric barrier discharge and corona discharge) clearly showed that the RGA plasma provided a significantly higher CH3OH conversion (28.6–95.6%) and a relatively high energy yield of H2 (8.5–32.0 g kW−1 h−1) while maintaining a processing capacity that was several orders of magnitude higher than the other plasmas. A mathematical model was established to predict the CH3OH conversion and energy yield of H2. The model sensitivity analysis indicated that the CH3OH concentration was the most influential parameter, whereas the water addition was the least important parameter for the reaction performance.
