A Co 3O 4-Fe 2O 3-MnO 2 monolithic catalyst supported on a mixture of yttria-stabilized zirconia (YSZ)-Al 2O 3 and La-modified CeO 2-ZrO 2 oxygen-storage material was prepared. The catalyst activity for methane combustion was measured in a microreactor, and a domestic natural gas premixed catalytic combustion fan-boiler prototype was developed on the basis of this methane combustion catalyst system. The monolithic catalyst showed high activity and good thermal stability, and the natural gas premixed catalytic fan-boiler showed the advantages of high thermal efficiency and low CO and NO x emissions. Hence, it is an energy saving and environmentally friendly product with high efficiency.
