  • Process for removing nitrogen oxides from gas using microwave catalytic reaction by microwave catalysis
    Patent number: 9199196
    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.
    Type: Grant

  • Microwave catalyst and preparation process and use thereof
    Patent number: 9168514
    Abstract: Provided is a microwave catalyst. The microwave catalyst comprises: i) an active catalyst component comprising a metal and/or a metal oxide; ii) a microwave-absorbing component comprising at least one of CuO, ferrite spinel, and active carbon; and iii) a support. The microwave catalyst can be used for denitration by microwave catalysis, and has advantages such as high denitration efficiency, low energy consumption, environmental friendliness, and low costs. Also provided is a process for preparing the microwave catalyst and the use thereof.
