Abstract: A method for drying a catalytic oxidation furnace, the method including: 1) charging a feed gas including oxygen and natural gas, and a temperature control gas to a catalytic oxidation furnace loaded with a catalyst; 2) preheating a mixed gas including the feed gas and the temperature control gas to increase the temperature of the mixed gas, and stopping the preheating when the temperature of the mixed gas achieves a temperature adapted to trigger the oxidation reaction of the mixed gas; and 3) within the molar ratio of the temperature control gas to the feed gas being 0.1-7:1.3-1.6, reducing the molar ratio of the temperature control gas to the feed gas such that the rise of the temperature of the mixed gas conforms to the temperature rising rate of the drying-out curve of a heat insulation refractory material of the catalytic oxidation furnace.
