Liquid ethanol introduced as microdroplets into the tip of microwave nitrogen plasma, operating at 2.45 GHz under atmospheric pressure, has been investigated. Injection of ethanol outside the region of plasma generation eliminated a problem of soot formation at that region, which was responsible for short reactor lifetime. Using liquid ethanol allows to save energy needed for vaporization. Hydrogen, carbon monoxide and solid carbon were the main outlet products. Other products detected with gas chromatography were CH₄, C₂H₄ and C₂H₂. The best results concerning hydrogen production were as follows: concentration in the outlet gas up to 28%, production rate up to 1043 L/h, energy yield up to 209 L per kWh of microwave power, and were obtained for liquid C₂H₅OH flow rate of 3.7 L/h. A numerical 0D model was used to determine contributions of chemical reactions in formation of measured gaseous products. Simplified model involving only radical reactions without any ions and electrons predicts final concentrations of main compounds quite well for microwave power up to 4 kW.

已经研究了在大气压下以2.45 GHz的频率将液态乙醇作为微滴引入微波氮等离子体的尖端。在等离子体产生区域之外注入乙醇消除了在该区域形成烟灰的问题，这是导致反应器寿命短的原因。使用液体乙醇可以节省蒸发所需的能量。氢，一氧化碳和固体碳是主要的出口产品。气相色谱法检测到的其他产物是CH ₄，C ₂ H ₄和C ₂ H _2。。有关制氢的最佳结果如下：出口气体中的浓度最高为28％，生产率最高为1043 L / h，每kWh微波功率的能源产量最高为209 L，并且是针对液态C ₂ H _5获得的OH流量为3.7 L / h。0D数值模型用于确定化学反应在测量的气态产物形成中的作用。仅涉及自由基反应而没有任何离子和电子的简化模型预测，对于功率高达4 kW的微波，主要化合物的最终浓度非常好。
