ABSTRACT:
There is presented a process for the treatment of exhaust gas, which process uses a specially prepared catalyst composition, for the selective catalytic reduction of NO.sub.x contained in the exhaust gas. An embodiment of the process of this invention comprises a catalytic stage to selectively catalytically reduce NO.sub.x over a catalyst composition comprising a molecular sieve that has been treated with a metal in a way effective to maximize metal dispersion. The catalyst of this invention typically comprises a silica, titania, or zirconia binder, e.g. a binder including a high molecular weight, hydroxyl functional silicone resin. The catalyst of this invention may be formed into a desired shape, e.g., by extrusion, and finished in a humidified atmosphere after forming.
