A series of Fe–Ce–Ti catalysts were prepared via co-precipitation method to investigate the effect of doping Ce into Fe–Ti catalysts for selective catalytic reduction of NO with NH3. The NO conversion over Fe–Ce–Ti catalysts was considerably improved after Ce doping compared to that of Fe–Ti catalysts. The Fe(0.2)–Ce(0.4)–Ti catalysts exhibited superior catalytic activity to that of Fe(0.2)–Ti ...

Mn-based catalysts enable high NO x conversion in the selective catalytic reduction of NO x with NH3. Three catalyst-production methods, namely, co-precipitation, impregnation, and sol-gel, were used in this study to determine the optimum method and parameters. The maximum catalytic activity was found for the catalyst prepared by sol-gel with a 0.5 Mn/Ti ratio. The denitrification efficiency us...

Abstract Mn-WO 3 /TiO 2 catalysts were investigated for Selective Catalytic Reduction (SCR) of NO with NH . The synthesized by wetness impregnation method different Mn loadings (1.5-3-12 wt%) on 8wt%WO All three compared and bare MnO x oxide, used as references. 1.5wt%Mn-8wt%WO exhibited the highest performance in conversion N selectivity. A commercial catalyst, based titania supported vanadia ...

The nitric oxide (NO) removal capacity of ion-exchanged zeolite Y obtained from coal combustion fly ash was evaluated in this work. Zeolite Y was exchanged either with Cu or Fe to obtain two different catalysts for the selective catalytic reduction of NOx from flue gas. The selective catalytic reduction experiments were carried out at temperatures ranging from 50°C to 350°C, water content 0% an...

In this paper, a systematic experimental and kinetic model investigation was conducted over Cu-SSZ-13 catalyst to study the DeNOx efficiency N 2 O formation for selective catalytic reduction of NOx with NH 3 (NH -SCR). The developed various reactions take place in -SCR system, including adsorption/desorption, oxidation, NO standard SCR, fast slow SCR reactions. addition, reaction from non-selec...

Cement production is the third largest source of nitrogen oxides (NOx), an air pollutant that poses a serious threat to natural environment and human health. Reducing NOx emissions from cement has become urgent issue. This paper aims explore investigate more efficient denitrification processes be applied in reduction precalciner. In this study, firstly, flow field, temperature component fractio...
