摘要：研究甲烷-烟气热化学重整反应机理对深入理解甲烷-烟气重整反应物之间的相互作用、优化甲烷-烟气重整反应条件和参数、提高甲烷-烟气重整反应产物收率和纯度至关重要。采用常压管式炉对不同实验条件下的甲烷干重整和甲烷蒸汽重整反应进行了实验研究,分析了不同实验参数对甲烷干重整、甲烷蒸汽重整反应过程、反应活性和选择性等方面的影响。结果表明,甲烷-烟气重整反应过程伴随着甲烷裂解反应的发生。在低于1100℃的反应温度下,甲烷裂解偏向于生成炭黑和H_(2)。在高于1100℃的反应温度下,甲烷裂解偏向于生成[C_(2)H_(2)]中间体和H_(2)。在相同反应条件下,甲烷蒸汽重整反应活性大于甲烷干重整反应活性。重整反应温度的提升有利于甲烷-烟气重整反应的进行。
Studying the mechanism of methane-flue gas thermochemical reforming reaction is crucial for a deeper understanding of the interactions between methane-flue gas reforming reactants,optimizing methane-flue gas reforming reaction conditions and parameters,and improving the reaction yield and purity of methane-flue gas reforming reaction products.Experimental studies were conducted on dry reforming of methane and steam methane reforming reactions under different experimental conditions using an atmospheric pressure tube furnace.The effects of different experimental parameters on the reaction processes,reaction activity,and selectivity of dry reforming of methane and steam methane reforming reactions were analyzed.The results indicate that the methane-flue gas reforming reaction process is accompanied by the occurrence of methane cracking reaction.At temperatures below 1100℃,methane cracking tends to generate carbon black and hydrogen gas.At temperatures above 1100℃,methane cracking tends to generate acetylene[C_(2)H_(2)]and hydrogen gas.Under the same reaction conditions,the activity of steam methane reforming reaction is greater than that of dry reforming of methane.The increase in reforming reaction temperature is beneficial for the progress of methane-flue gas reforming reaction.
