Abstract
The dehydrogenation of methane was carried out over a Mo/ZSM-5 catalyst. It was revealed that the purity of the methane was very critical for the evaluation of the catalyst activity. In order to study the phenomenon, the effects of the addition of O2, CO2, CO or H2 to the feed were investigated. A small amount of O2 increased the amounts of aromatic compounds and CO produced. The addition of H2 scarcely affected the conversion of methane, but it prevented the deactivation of the catalyst, i.e., benzene production remained constant during a 6 h test.
