Catalytic partial oxidation of methane over rhodium coated foam monolith

The catalytic partial oxidation of methane(CPOM) to syngas was studied on a rhodium coated foam monolith catalyst.The influences of reactor temperature,space velocity and methane/oxygen ratio were investigated and discussed.The reaction could be maintained auto-thermally after ignition.Under the conditions of high space velocity(8.0×105 h-1) and methane/oxygen ratio of 1.8,the methane conversion,hydrogen selectivity and carbon monoxide selectivity exceeded 90%,90% and 95%,respectively.Heat supply to the reactor increased methane conversion and selectivity to hydrogen and carbon monoxide.
