脉冲电晕等离子体活化纯CO_2的反应

Investigation on the conversion of pure CO_2 by pulse corona plasma

研究了在常温常压下，脉冲电晕等离子体对温室气体CO2的活化与转化分别考察了反应气体流速、脉冲电压峰值、放电频率对纯CO2转化的影响．结果表明，CO2主要分解为CO和O2，另有少量积碳和臭氧产生；随着反应气体流速的增加，CO2转化率、CO产率和选择性降低；随着脉冲电压峰值和放电频率的升高，CO2转化率、CO产率增大，CO选择性降低．

At atmospheric pressure and ambient temperature, the activation and conversion of CO2 using pulse corona plasma was studied. Effects of gas flow rate, peak value of pulse voltage as well as discharge frequency on the conversion of pure CO2 were investigated. Experimental results showed that CO2 gas was mainly transferred to CO and O2, with a small amount of C and O3 as by products. The conversion of rate CO2, the yield and the selectivity of CO were decreased with increasing flow rate of reactant gas. However, with increasing peak value of pulse voltage and discharge frequency,the conversion rate of CO2 and the yield of CO are promoted, while the selectivity of CO was dropped.
