Decomposition of Carbon Dioxide by Dielectric Barrier Discharge Plasma

  • 摘要:

    温室效应导致全球变暖已成为全球性的环境问题之一. 采用放电等离子体法转化CO2,不仅可消纳温室气体,缓解全球变暖的巨大影响,还可制备化工原料CO和O2.充分利用了C1(含1个碳原子的化合物分子)资源, 对高频同轴式介质阻挡放电等离子体分解纯CO2进行了研究.结果发现:在采用不锈钢光滑内电极,放电间隙为2.0 mm,注入功率为180 W,气体流量为170 mL/min的条件下,CO2转化率可达18.2%,CO和O2产率分别为10.1%和4.7%;增大注入功率,减小气体流量、选择合适的放电间隙和内电极形式,均有利于提高CO2转化率,获得更多的CO和O2.
