Abstract

The character of carbonaceous deposits formed during methane dehydroaromatization reaction in the presence of Mo/ZSM-5 catalysts was studied by differential thermal analysis. The dependence of the concentration and condensation degree (C/H ratio) of the carbonaceous deposits on the catalyst synthesis conditions (Mo content = 1-10%, Si/Al ratio in the initial H-ZSM-5 = 17-45) and reaction conditions (feed flow
rate = 405-1620 h-1, methane concentration = 90-98%, reaction temperature = 720-780 °C) was investigated.
The oxidative treatment conditions of carbonized Mo/ZSM-5 catalysts providing stable operation of the
catalysts under multiple reaction-oxidative treatment cycles were selected.
