Abstract
A study was carried out on the activity of high silicon cation-exchanged zeolites containing Period IV metals (Fe, Cu, Zn, and Co) and lanthanides (La and Ce) in the reduction of nitrogen oxides by C3-C4 hydrocarbons in an oxidizing atmosphere and the kinetics of this process for the copper and cerium catalysts, which display the highest activity. The catalyst activity is a function of the nature of the cation introduced, extent of exchange of sodium by the corresponding cation, SiO2/Al2O3 ratio of the zeolite, and acidity of the catalyst surface.
