摘要
本文采用切向气流和磁场协同驱动的旋转滑动弧低温等离子体,以氮气为载气,进行了甲烷重整制氢的研究。考察了进气流量,CH_4/N_2比和外加电阻对制氢效果的影响,结果表明,随着进气流量的增加,甲烷转化率逐渐降低;随着CH_4/N_2比的增大,外加电阻为40 kΩ时,甲烷转化率逐渐降低,最大可达87.49%,而外加电阻为70 kΩ时,甲烷转化率却先降低后增大;减小外加电阻有利于增加甲烷转化率和氢气选择性,但会造成能耗的增加。
A rotating gliding arc co-driven by tangential flow and magnetic field was used for hydrogen production from methane reforming in nitrogen. Effect of gas flow, CH4/N2 ratio and resistance on performance of methane reforming was investigated. The results show that, as gas flow rate grows, methane conversion decreases.For the 40 kΩ resistance, methane conversion decreases with rising CH4/N2 ratio. The maximum value is up to 87.48%. Whereas, for the 70 kΩ resistance, methane conversion first decreases and then increases for CH4/N2 increasing. A lower resistance is beneficial for methane conversion and hydrogen selectivity, but leads to higher energy consumption simultaneously.
