Abstract

Abstract: The effect of ethane addition on methane dehydroaromatization over a Mo/HZSM-5 catalyst was investigated. It was revealed that the ethane addition could not promote the conversion of methane but produced methane and increased coke deposition rate, causing rapid deactivation of the catalyst. However, ethane accelerated the formation of Mo active centers (Mo₂C and/or MoO_xC_y species), shortening the induction period and moving the benzene formation forward.

Key words: methane, ethane, dehydroaromatization, molybdenum, HZSM-5 zeolite
