The focus of the research was the process of hydrogen production from a mixture of water and ethanol in plasma and plasma-catalytic reactors. Plasma was produced in a dielectric barrier discharge. The catalyst was cobalt supported on ZrO2 (Co/ZrO2). The catalyst was placed in the grooves of the high voltage electrode. The ethanol conversion was similar in both studied reactors and increased from 34 to 55% with increasing discharge power from 20 to 60 W. However, hydrogen production in the plasma-catalytic reactor was up to 2.4 times greater than in the plasma reactor. The highest energy efficiency of hydrogen production in the plasma catalytic reactor was 7.7 mol(H2)·kWh-1. In the plasma reactor, the concentration of products was constant in the tested range of discharge power. In the plasma-catalytic reactor, H2 and CO2 concentrations increased with increasing discharge power, whereas concentrations of CO, CH4, C2H4, and C2H6 were decreased. The maximum H2 concentration was 56%.

使用特殊的多段等离子体催化反应器从乙醇中制氢

研究的重点是在等离子体和等离子体催化反应器中由水和乙醇的混合物生产氢气的过程。在介电势垒放电中产生等离子体。催化剂被钴负载在ZrO 2(Co / ZrO 2)上。将催化剂放置在高压电极的凹槽中。在两个研究的反应器中,乙醇的转化率相似,并且随着放电功率从20 W增加到60 W,乙醇转化率从34%增至55%。但是,等离子体催化反应器中的产氢量最多是等离子体反应器中的2.4倍。等离子体催化反应器中制氢的最高能量效率为7.7 mol(H 2)·kWh-1。在等离子体反应器中,产物的浓度在测试的放电功率范围内是恒定的。在等离子体催化反应器中,H 2和CO 2的浓度随着放电功率的增加而增加,而CO,CH 4,C 2 H 4和C 2 H 6的浓度降低。H 2的最大浓度为56%。
