Abstract: | Catalytic partial oxidation of methane was investigated in a reverse flow reactor with commercial Rh/Al2O3 catalyst in pellets. The process is carried out in a catalytic fixed bed reactor and switching of feed flow direction is obtained through four electrovalves synchronized in pairs. Temperature profile along the catalyst bed was measured by fast IR thermography and product composition was measured with a continuous gas analyzer.Feed direction switching time, water to methane ratio and inert section length were investigated as process parameters.Data of catalyst bed temperature evolution during the flow cycle are presented, discussed and related to reactor performance as a function of reverse flow switching period.The effect of water addition to the reacting mixture on the dynamics of catalyst bed temperature evolution is also presented. |
