NOx Removal by LNT-SCR Dual-layer Catalysts
The increasingly strict emission standards have driven the progress of NOx storage and reduction (NSR) technology. NOx is stored in a lean NOx trap (LNT) catalyst during fuel-lean mode and reduced to N2 during fuel-rich ...
Experimental and Kinetic Modeling Studies of Selective Catalytic Reduction of NOx with NH3 on Fe- and Cu-Zeolite Monolithic Catalysts
The selective catalytic reduction (SCR) of NOx with NH3 is considered to be the most promising technique for the efficient reduction of highly detrimental NOx (to N2) emitted from diesel engine vehicles. Amongst the various ...
