The exploitation of methane to produce aromates is already seen for a long time as very attractive. Although investigated intensively, methane dehydro‐aromatization (MDA) is far from being applied industrially. MDA under non‐oxidative conditions is severely limited by thermodynamics and rapid catalyst deactivation. Mo/MCM‐22 was reported as a promising catalyst. Thus, kinetic experiments were performed to parametrize rate expressions and to identify trends regarding the selectivity‐conversion behavior including catalyst deactivation. Finally, mass transfer was described mathematically to evaluate the potential of hydrogen‐selective membranes within a membrane reactor of the extractor type. Such a removal would be beneficial to overcome the thermodynamic limitations.
