Catalytic Chemistry for Methane Dehydroaromatization (MDA) on a Bifunctional Mo/HZSM‑5 Catalyst in a Packed Bed

This
paper presents an experimental and modeling study of methane
dehydroaromatization (MDA) chemistry using a bifunctional 6 wt % Mo/HZSM-5
catalyst in an isothermal laboratory-scale packed-bed configuration.
The reported measurements include methane conversion and product yields
and selectivities as a function of temperature and flow rates (space
velocity). The modeling is particularly concerned with developing
and validating a microscopically reversible 54-step detailed reaction
mechanism. The reaction mechanism is validated via direct comparison
with the measured packed-bed performance. Although the operating conditions
for the measurements are relatively limited, the detailed reaction
mechanism is expected to have much wider predictive capability.
