Dehydro-aromatization of methane under non-oxidative conditions over MoMCM-22: effect of surface aluminum removal

摘要

The dehydro-aromatization of methane was studied over molybdenum carbide supported on HMCM-22 zeolite, with high benzene selectivity at 973 K. Extensive aluminum removal promoted an increase in benzene selectivity (to more than 80%) and in stability. That increase in stability was attributed to the decrease of coke production on the surface, thus reducing pore blockage.
