摘    要:在低温常压条件下,研究了在无声放电反应器中以A型分子筛为催化剂从甲烷和二氧化碳合成烃和合成气,实现了在无声放电反应器中同时合成烃和合成气。实验在原料气流量200-600ml/min、原料气甲烷和二氧化碳摩尔比1/1-3/1及输入功率100-500W的范围内进行。研究结果表明,低原料气流量有利于甲烷和二氧化碳的转化,而高原料气流量有利于烃的生成;原料气甲烷和二氧化碳摩尔比对制得合成气的H2/CO摩尔比的影响最显著;甲烷和二氧化碳转化率及合成气和烃的产率均随输入功率的增加而提高。而所研究的范围内,当原料气流理为200ml/min、甲烷和二氧化碳摩尔比为1/1、输入功率为500S时,甲烷和二氧化碳转化率达到最高值,分别为64%和39%。以此法制备的合成气的H2/CO摩尔可以在很宽的范围内变化,本研究合成气H2/CO摩尔比的变化范围是0.7-3.1。

关 键 词:二氧化碳  甲烷  无声放电  温室气体    合成气  一氧化碳  氢气  摩尔比

Abstract:Two major greenhouse gases, methane and carbon dioxide, were converted to syngas and hydrocarbons over zeolite catalyst at low temperature and atmospheric pressure in a high power dielectric barrier discharge reactor. Co-generation of syngas and hydrocarbons was demonstrated in such a reactor.Parameters investigated in this study included flow rate of the feed gas, the input power and the molar ratio of CH 4 to CO 2 in the feed. Results indicated that low flow rate favored the conversion of CH 4 and CO 2 while high flow rate led to the production of hydrocarbons. Increasing the input power resulted in high conversion of methane and carbon dioxide and high productivity of syngas and hydrocarbons. The ratio of CH 4/CO 2 in the feed gas had the most significant effect on the ratio of H 2/CO in syngas. The highest conversion of CH 4 and CO 2 was 64% and 39%, respectively, at a molar ratio of CH 4/CO 2 of 1/1, a total flow rate of 200 ml/min and an input power of 500 W. Soproduced syngas showed an arbitrary composition (H 2/CO ratio) with molar ratio of H 2/CO varied in the range from 0.7 to 3.1.
Keywords:carbon dioxide  dielectric barrier discharge  greenhouse gases  hydrocarbons  methane  syngas
