Research Progress in Flue Gas Denitrification Technology Based on Oxidation Theory

Abstract

Because of its mild reaction condition, relatively high denitrification efficiency and ability of combined removal of various pollutants, the flue gas denitrification technology based on oxidation theory has become a new and feasible method for flue gas denitrification. The technology has been applied extensively and studied in depth. This paper reviews the influencing factors, reaction mechanism, reaction products and subsequent absorption reaction of the oxidation of NO in flue gas with gas phase and liquid phase oxidants at high and low temperatures. On this basis, the shortcoming of the technology and the key research directions for the future are analyzed and discussed, laying the basis for industrial applications of the denitrification technology based on oxidation theory.
