SOME METHODS OF REDUCING NOx COMPONENTS IN EXHAUST GAS

Abstract

NOx nitrogen emissions arise through the burning of fuels at high temperatures, through chemical processes that use nitrogen. In nature, from the nitrogen oxidation of the air due to lightning, volcanic gas and microbial decomposition processes. Nitrous oxides normally exist in the air at very small concentrations and do not cause pollution concerns. However, along with the development of transportation, vehicles that emit NOx emissions beyond the permitted levels are seriously affecting the air quality. This article presents some solutions to absorb or convert NOx in waste gases to reduce environmental pollution.
