Abstract

Mn-Ce/FA (M) and Mn-Ce/FA-TiO 2 (M), using fly ash (FA) with and without TiO 2 as the carriers, were prepared by an integral molding technique. With the increase of TiO 2 content, the rates of NO conversion and denitration of Mn-Ce/FA-TiO 2 (M) increased, and the NO 2 and N 2 O formation rates decreased. It is found that TiO 2 could effectively inhibit the excessive oxidation of NO and the generation of N 2 O. The effects of space velocity, oxygen concentration and ammonia nitrogen ratio on three types of nitrogen oxides (NO, NO 2 , N 2 O) and denitration rates of the Mn-Ce/FA (M) and Mn-Ce/FA-30%TiO 2 (M) were further investigated. In addition, it is demonstrated that Mn-Ce/FA (M) and Mn-Ce/FA-30%TiO 2 (M) were more suitable to be used in the environment of low sulfur and less water.
