Blanchard, G. (author), Van den Bleek, C. (author), Calis, H.P. (author), Kruse, N. (author), Noirot, R. (author), Tachon, D. (author), Seijger, G. (author)The invention concerns catalytic compositions comprising a zeolite and methods for reducing nitrogen oxides (NOx) using said catalytic compositions. The inventive catalytic compositions comprise a ferrierite type zeolite (FER), which has been subjected to an ion-exchange with a rare earth selected among cerium, praseodymium, samarium, terbium,...patent 2003

Seijger, G.B.F. (author), Van den Bleek, C.M. (author), Calis, H.P.A. (author)The invention is directed to catalyst compositions comprising a zeolite, as well as to processes for the reduction of nitrogen oxides (NOx) employing these catalyst compositions. The catalyst compositions of the invention comprise a zeolite of the ferrierite type (FER), which zeolite is ion exchanged with Ce, in particular Ce-H-FER and are very...patent 2003
