由CO_(2)造成的温室效应已成为全球面临的重要气候问题。针对目前处理技术存在能耗大、工艺复杂、环境污染等问题,本文提出了一种基于大气压微波等离子体的快速清洁的处理方法,使用大气压微波等离子体系统实现CO_(2)的快速转化,通过通入Ar与CO_(2)的混合气体,将CO_(2)转化为CO和O_(2),其中CO_(2)的转化率最高可达19.37%;研究了微波输入功率、混合气体配比、气体流速及混合进气管长度对转化率的影响,得到了最优反应条件,研究结果表明大气压微波等离子体转化CO_(2)具有良好的工业应用前景。

The greenhouse effect caused by CO_(2) has become a serious global climate issue.In response to the huge energy consumption,process complexity,and environmental pollution issues of current CO_(2) treatment technologies,a clean and fast treatment method based on atmospheric pressure microwave plasma is proposed.An atmospheric microwave plasma system is used to perform CO_(2) conversion.By introducing a mixture of Ar and CO_(2),CO_(2) is converted into a mixture of CO and O_(2),and the maximum conversion rate of CO_(2) reaches 19.37%.The effects of microwave input power,ratios of mixed gases,gas flow rate,and length of mixed intake pipe on conversion rate are studied,and the optimal reaction condition is obtained.The research indicates that atmospheric pressure microwave plasma conversion of CO_(2) has good industrial application prospects.
