Plasma-Assisted Removal of NO from Gas Streams via Ammonia Injection

摘要

Removal of nitric oxide (NO) from gas streams via combined NH_3 injection with dielectric barrier discharge (DBD) plasmas was experimentally investigated. Removal of NO was principally achieved via its reaction with NH_I radicals generated with DBD plasmas. Removal efficiency of NO was mea- suref as a function of stoichiometric ratio, applied voltage, and inlet NO concentration of the gas stream. Experimental results showed that as much as 80/100 of NO was removed from gas streams operating at room temperature.
