英文摘要The promotion effect of CO in methane dehydroaromatization was investigated using (CO)-C-13 probe molecules. By alternative injection of (CO)-C-13 to the methane feed, the distribution of (CxC6-xH6)-C-13 (x = 0-3) products changed significantly, confirming the participation of (CO)-C-13 in the reaction network. The addition of (CO)-C-13 did not change the conversion of CH4 but improved slightly the durability of the methane dehydroaromatization (NIDA) reaction, which might be caused by the interaction of the dissociated oxygen species and the deposited carbon species. The ratio of (CxC6-xH6)-C-13 (x = 0-3) varied with the time on stream, which was determined by the competitive reactions of methane decomposition and (CO)-C-13 dissociation.
