The invention concerns, on one hand, a new zeolitic catalytic composition which comprises a small-pore mordenite present in the form of needles, exchanged with at least one metal chosen from the group consisting of cooper, vanadium, tungsten, iron, colbalt and molybdenum, and on the other hand, use
The invention concerns, on one hand, a new zeolitic catalytic composition which comprises a small-pore mordenite present in the form of needles, exchanged with at least one metal chosen from the group consisting of cooper, vanadium, tungsten, iron, colbalt and molybdenum, and on the other hand, use of this catalytic composition as a catalyst for the reduction of nitrogen oxides by ammonia.

A zeolitic catalytic composition comprised of a small-pore mordenite exchanged with at least one metal chosen from the group consisting of copper, vanadium, tungsten, iron, cobalt and molybdenum, the small-pore mordenite used for the exchange being the sodium, ammonium or protonic form, a major part
A zeolitic catalytic composition comprised of a small-pore mordenite exchanged with at least one metal chosen from the group consisting of copper, vanadium, tungsten, iron, cobalt and molybdenum, the small-pore mordenite used for the exchange being the sodium, ammonium or protonic form, a major part of the mordenite being present in needle form and having the property of only adsorbing molecules of a kinetic diameter less than 4.4×10-10 m, said mordenite being dealuminated at least in part so as to improve performance of the catalyst in removal of NO, N2O, NH3, and SO3 from effluent gases.
