Migration, reactivity, and sulfur tolerance of copper species in SAPO-34 zeolite toward NOx reduction with ammonia 来自 Semantic Scholar 喜欢 0 阅读量: 87 作者:X Liu,X Wu,D Weng,Z Si,R Ran 摘要: Cu/SAPO-34 catalysts were prepared by wet impregnation and ion-exchange methods, and both ...
The -selective catalytic reduction (SCR) reaction of NO with excess of oxygen were systematically investigated over Cu-zeolite and Fe-zeolite catalysts. Cu-zeolite and Fe-zeolite catatysts to adapt the SCR technology for mobile diesel engines were prepared by liquid ion exchange and incipient wetne...
Catalytic reduction of nitrogen oxides (NO x ) by ammonia is one of the most promising methods for cleaning waste gases from NO x in the presence of oxygen. In the practice, there are widely used high-percentage vanadium oxide catalysts. NO x is selectively reduced by ammonia in the ...
However, the NOx emissions increased with the increment of CA/GA ratios (from 2.8 to 3.2). Therefore, future works must address the NOx emission reduction without penalizing performance or permanent emissions from the TLUD cookstoves.Similar content being viewed by others Energy and exergy analysis...
The desired reaction is NO reduction by ammonia: 4NO + 4NH3 + O2 4N2 + 6H2O However, ammonia can at the same time undergo oxidation: (1) 4NH3 + 3O2 2N2 + 6H2O (2) The heterogeneous catalytic conversion of NO to N2 is described by an Eley-Rideal mechanism. A key reaction step...
The selective reduction of NOx, with ammonia on alumina-supported copper catalysts is shown to be effective when O2 or NO2 are present in the feed. Under steady state conditions, the presence of NO2 in the feed stream increases the overall rate of reduction of NOx and simultaneously reduces ...
Reduction of nitric oxides in the exhaust of Diesel-engines by urea-SCR is a well known technique for stationary operating engines. Conversion rates of up to 99 % are possible without slip of ammonia. However the application of urea-SCR for vehicles like trucks or passenger cars fitted with ...
Our catalytic filter bags achieve both NOx reduction and ammonia filtration within your existing baghouse, with no need to do anything more than change your filter bags. Upgrade your baghouse to an SCR With more than 15 years of experience in catalytic NOx reduction, Gore has developed a compl...
The present invention is directed to an iron-promoted zeolite beta catalyst useful in the selective catalytic reduction of nitrogen oxides with ammonia in which the iron-promoted zeolite beta is treated so as to provide increased amounts of the iron promoter in the form of Fe(OH). ...
