非热等离子体CH4-CO2重整产物分布调控的研究
Study on product distribution regulation of non-thermal plasma CH4-CO2 reforming
摘要
Abstract
To address the issue that the traditional thermal catalytic conversion of CH4 and CO2 requires high temperature and high pressure and achieve the efficient utilization of two greenhouse gases,non-thermal plasma technology can be used to directly convert CH4 and CO2 to high-value chemicals(methanol,ethanol and acetic acid,etc.)at room temperature and atmospheric pressure.The regulation of reaction gas conversion rates and product distributions by reaction gas n(CO2)∶n(CH4),total reaction gas flow rates and discharge powers was investigated,and the effects of catalysts on the performances of reaction system were studied.The results show that when the n(CO2)∶n(CH4)is 3∶1,and total reaction gas flow rate is 40 mL/min,and discharge power is 25 W,the selectivity of oxygenates is 75％,and the selectivity of acetic acid is 47％.When Cu catalyst is used,the selectivity of propanoic acid can reach 36％.When ZnO catalyst is used,the selectivity of oxygenates increases to 92％,and the selectivity of the main product methyl formate reaches 37％.The larger the reaction gas n(CO2)∶n(CH4),the more favorable it is for the reaction gas conversion and formation of acetic acid.The smaller the total reaction gas flow rate,the larger the conversion rate of reaction gas.The larger the discharge power,the larger the conversion rate of reaction gas,but excessive discharge power will lead to a decrease in selectivity of oxygenates.The use of catalysts in this reaction system can generate new products with greater economic value.关键词
