Hydrogen production by methanol decomposition using gliding arc gas discharge
-
摘要: 对常温常压下滑动弧放电等离子体直接分解甲醇进行了研究,探讨了载气流量、甲醇浓度、电极间距、输入电压和气化室温度等实验参数的影响。结果表明,不同操作条件导致甲醇转化率由51%升高到81.7%,氢气和一氧化碳的选择性之比基本保持一个固定值。除了氢气和一氧化碳,产物中还检测到了少量的甲烷和C2不饱和烃以及痕量二氧化碳。不同于传统的甲醇热分解机理,提出了滑动弧放电等离子体甲醇分解的制氢路径。Abstract: Direct decomposition of methanol has been investigated using gliding arc gas discharge (GRD) at atmospheric pressure. Depending on the experimental conditions of Ar flow rate, methanol concentration, the electrode gap, input voltage and vaporization room temperature (VRT), different conversions are achieved ranging from 51.0% to 81.7%. Interestingly, the selectivity to the production of hydrogen and carbon monoxide is kept almost constant under all the experimental conditions. The formation of little methane and C2Hx as a byproduct, and trace quantity of carbon dioxide are detected. The reaction channels of methanol decomposition induced by GRD plasma is proposed in detail.
