Autothermal CO₂ reforming of methane over NiO-MgO solid solution catalysts under pressurized condition: Effect of fluidized bed reactor and its promoting mechanism

The effect of fluidized bed reactor in autothermal CO₂ reforming of methane over NiO-MgO solid solution catalysts was investigated by comparing with fixed bed reactor. Methane conversion to syngas was drastically enhanced by using a fluidized bed reactor. The catalyst was reduced and oxidized repeatedly in fluidized bed reactor during the reaction. The enhancement of methane conversion is related to the catalyst reducibility.
