介质阻挡放电裂解CO_2的实验研究

Study of CO_2 Splitted by DBD Plasma

考察了CO_2进气流量、放电功率、放电频率对介质阻挡放电(DBD)裂解CO_2反应的影响。结果表明,CO_2转化率随着CO_2进气流量的增加而减小,随着放电功率的增加而增加,随着放电频率的增大略微减小,但变化幅度不大。DBD转化CO_2能量效率几乎不随CO_2进气流量和放电功率改变,仅随放电频率有所改变。

Experiments with different flow rate of CO2, input power and discharge frequency were carried out. The experimental result showed that the CO2 conversion decreases with the increase of CO2 inlet flow, increase with the effective input power increases. Although reducing discharge frequency will increase CO2 conversion, but the growth is not obvious. However the system energy efficiency only small changes when the discharge frequency change, it has nothing to do with the CO2 inlet flow rate and effective power input.
