Abstract
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.
