Abstract

The reduction of NO in the presence of excess oxygen with propane and propylene over Ni-exchanged zeolites was examined. Incorporation of Ni resulted in the formation of Bronsted acid sites resulting from the hydrolysis of divalent Ni ions. Calcined catalysts exhibited a high selectivity to N₂ formation, while after reduction of the Ni species significant concentrations of NO₂ and N₂O were formed. Higher NO conversions were obtained with propane compared to propylene except for NiNaMOR catalysts with low Ni content. The concentration of acid sites did not play a major role in the NO reduction, high acid site concentrations, however, led to the formation of coke. This is an abstract of a paper presented at the 13^th International Zeolite Conference (Montpellier, France 7/8-13/2001).
