摘要
CO2的转化再利用是解决碳排放的一种重要策略.作为非热等离子体的一种,滑动弧等离子体非常适合应用于CO2转化.研发了一种新型磁稳定滑动弧放电装置,将它用于CO2转化产生CO与O2.系统研究了磁稳定滑动弧的放电形态和电学特征,以及外加磁场对反应转化率的影响.结果表明,相比于传统的滑动弧装置,该磁稳定滑动弧放电装置可以获得更高的CO2转化率.通过改变气体流速,研究发现在0.5 L/min时,CO2转化率达到峰值(13.23%),此时对应的能效为20.29%;在1.5 L/min时,CO2转化率为6.34%,此时能量效率达到最大(30.51%).将该结果与其他等离子体装置所得结果进行了对比,结果表明该磁稳定滑动弧装置用于CO2转化具有一定的优越性.
Abstract
Conversion and reuse of CO2 is an important strategy to address carbon emissions,as a type of non-thermal plasma,sliding arc plasma is ideally suited for CO2 decomposition applications.In this paper,a magnetically stabilized sliding arc discharge device is investigated for the conversion of CO2 to produce CO and O2.We have systematically studied the discharge morphology and electrical characteristics of the magnetically stabilized sliding arc,as well as the effect of the applied magnetic field on the reaction conversion rate.The results show that the applied magnetic field leads to a higher CO2 conversion rate compared to the conventional sliding arc system.By further varying the flow rate,we found that at a flow rate of 1.5 L/min,the CO2 conversion was 6.34%and the energy efficiency was 30.51%;at 0.5 L/min,the CO2 conversion could reach 13.23%and the energy efficiency was 20.29%.In the end,we compare the reaction results with other plasma systems to demonstrate the superiority of the magnetically stabilized sliding arc.
