Mn-Ce catalysts/LDPC Modified by Mo for Improving NH3-SCR Performance and SO2 Resistance at Low Temperature

نویسندگان

چکیده

Mn-Ce catalysts modified by Mo were loaded on low-density porous ceramics (LDPC) for simultaneous denitrification and dust removal. The Mn-Ce-Mo catalyst LDPC had nearly 99% NOx conversion efficiency from 120 °C to 200 still maintained more than 90% when the filtration velocity reached 4 m/min. catalysts/LDPC not only exhibited excellent catalytic performance at low temperature, they also good resistance H2O SO2. remained above 89% 160 flue gas contained 100 ppm SO2 7 vol.% H2O. analysis of NH3-TPD XPS confirmed that Mn2Ce1Ox with stronger surface acidity adsorbed oxygen, leading higher NH3-SCR activity better

Poisoning Effect of SO2 on Honeycomb Cordierite- Based Mn–Ce/Al2O3Catalysts for NO Reduction with NH3 at Low Temperature

Honeycomb cordierite-based Mn–Ce/Al2O3 catalysts were prepared by the impregnation method and used for low-temperature selective catalytic reduction (SCR) of NOx with NH3, with and without SO2 and/or H2O in a homemade fixed-bed tubular reactor. The catalyst reached nearly 80% NOx conversion at 100 ◦C in the absence of SO2. However, SO2 reduces the catalytic activity (80% to 72%) of the honeycom...

NH3-SCR performance and the resistance to SO2 for Nb doped vanadium based catalyst at low temperatures.

Niobium oxide as the promoter was doped in the V/WTi catalyst for the selective catalytic reduction (SCR) of NO. The results showed that the addition of Nb2O5 could improve the SCR activity at low temperatures and the 6wt.% additive was an appropriate dosage. The enhanced reaction activity of adsorbed ammonia species and the improved dispersion of vanadium oxide might be the reasons for the ele...

Effect of Ce/Y Addition on Low-Temperature SCR Activity and SO2 and H2O Resistance of MnOx/ZrO2/MWCNTs Catalysts

The effects of SO2 and H2O on the low-temperature selective catalytic reduction (SCR) activity over MnOx/ZrO2/MWCNTs and MnOx/ZrO2/MWCNTs catalysts modified by Ce or Y was studied. MnCeZr and MnYZr catalysts reached nearly 100% and 93.9% NOx conversions at 200 ◦C and 240 ◦C, respectively. They displayed a better SO2 tolerance, and the effect of H2O was negligible. The structural properties of t...

Iron-doped Mn-Ce/TiO2 catalyst for low temperature selective catalytic reduction of NO with NH3.

The catalysts of iron-doped Mn-Ce/TiO2 (Fe-Mn-Ce/TiO2) prepared by sol-gel method were investigated for low temperature selective catalytic reduction (SCR) of NO with NH3. It was found that the NO conversion over Fe-Mn-Ce/TiO2 was obviously improved after iron doping compared with that over Mn-Ce/TiO2. Fe-Mn-Ce/TiO2 with the molar ratio of Fe/Ti = 0.1 exhibited the highest activity. The results...

Improved low temperature NH3-SCR performance of FeMnTiO(x) mixed oxide with CTAB-assisted synthesis.

FeMnTiOx mixed oxide is prepared by the CTAB-assisted co-precipitation method, and the transformation of anatase into rutile is inhibited by CTAB to some extent. The catalyst obtained in the present work shows nearly 100% NO conversion at 100-350 °C, more than 80% N2 selectivity at 75-200 °C, and excellent H2O durability for the selective catalytic reduction of NO by NH3 with a space velocity o...
