Abstract
A method for removing nitrogen-oxides by microwave assisted catalysis, including: 1) charging a catalyst capable of absorbing and interacting with microwave into a reaction tube of a reactor device, to form a reaction bed; and 2) heating the reaction bed by microwaves; when a temperature of the reaction bed is raised to 100-600° C., passing a gas containing nitrogen-oxides through the reaction bed, and performing a gas-solid reaction between the gas and the catalyst to remove the nitrogen-oxides from the gas.
