甲烷-烟气热化学重整反应机理研究OA

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 1 100℃,methane cracking tends to generate carbon black and hydrogen gas.At temperatures above 1 100℃,methane cracking tends to generate acetylene[C2H2]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.
