Methane autothermal reforming in a reverse flow reactor on Rh/Al2O3 catalyst

Autothermal reforming of methane was investigated in a Reverse Flow Reactor with commercial Rh/Al2O3 catalyst in pellets. The process was carried out in a catalytic fixed bed reactor and switching of feed flow direction was obtained through four electrovalves synchronized in pair. Temperature profile of the catalyst bed was measured by fast IR thermography and product composition was measured with a continuous gas analyzer. Reactor performance and catalyst temperature profile are presented as a function of feed direction switching period, water to methane inlet ratio and total inlet flow rate. Results are compared to steady state operation.
