PREPARATION METHOD OF CATALYST FOR SYNCHRONOUS PURIFICATION OF NO AND VOLATILE ORGANIC POLLUTANTS IN FLUE GAS

Disclosed is a preparation method of a catalyst for synchronous purification of NO and volatile organic pollutants in flue gas comprising: solving 5-10 mmol of cerium salt and 0.1-0.5 mmol of heteropoly acid in 50-100ml of solution, stirring for 1 hour; adding 0.5-2g of structure directing agent into the mixed solution, stirring for 0.5 hour; moving the solution into a hydrothermal reaction kettle, with a hydrothermal temperature of 80-180℃ and hydrothermal time of 6-48 hours; washing and filtering a hydrothermal reaction product, placing the product in an oven at 105℃ for drying for 12 hours; roasting a dried solid in a muffle furnace; screening a roasted product. The method is suitable for synchronous removal of NO and volatile organic pollutants at a low temperature, realizes efficient purification of flue gas of a waste incineration plant, is low in investment and operation cost and easy for industrial application.
