摘要:

利用液相阵列电极滑动弧放电等离子体分解甲醇来优化现有制氢技术,系统研究了不同电极配置对制氢性能的影响。获得最优极配数量,发现同放电功率下4针电极最大氢气流速达到1188.54 ml/min,相对于单针提高了118%。此外,在液相放电中阵列针-环结构相比阵列针-孔板结构具有更高的氢气产能和能量产率。在阵列针-环电极配置工况,滑动弧放电等离子体分解甲醇表现出最佳制氢性能,能量产率69.75 g/kWh,能量效率71.12%,优于现有大多数制氢方案。

Abstract:

By utilizing liquid-phase array electrode gliding arc discharge plasma to decompose methanol, the existing hydrogen production technology was optimized, and the influence of different electrode configurations on hydrogen production performance was systematically studied. The optimal number of electrode configurations was obtained, and it was found that the maximum hydrogen flow rate of the 4-needle electrode reached 1188.54 ml/min at the same discharge power, which was 118% higher than that of the single needle. Furthermore, in the liquid-phase discharge, the array needle ring structure exhibited higher hydrogen production capacity and energy yield compared to the array needle hole-plate structure. When using the array needle-ring structure, the gliding arc discharge plasma decomposition of methanol demonstrated the best hydrogen production performance, with an energy yield of 69.75 g/kWh and an energy efficiency of 71.12%, which is better than most existing hydrogen production schemes.

Key words: liquid-phase discharge, plasma, methanol, hydrogen production, optimization
