PROCESS FOR REMOVING NITROGEN OXIDES BY MICROWAVE CATALYSIS

摘要

Disclosed is a process for removing nitrogen oxides by microwave catalysis, comprising: 1) charging a microwave catalyst capable of absorbing and interacting with microwaves into a reaction tube of a microwave catalysis reactor device, to form a bed layer for the microwave catalysis; and 2) passing a nitrogen oxides-containing gas to be treated through the bed layer for the microwave catalysis when the bed layer for the microwave catalysis is raised to a temperature of 100-600°C by absorbing microwaves with the microwave catalyst, subjecting the gas to a gas-solid reaction with the microwave catalyst, and removing the nitrogen oxides in the gas to be treated.
