Selective Catalytic Reduction of NO with NH₃ over a Ce-Zr-Ti Oxide Catalyst

Abstract:

A Ce-Zr-Ti composite oxide catalyst was prepared by the sol-gel method and its NH₃-SCR activities were investigated. The Ce-Zr-Ti oxide catalyst exhibited high activity and 92.7-98.8% NO conversion was obtained in the temperature range 250-450 °C at the high gas hourly space velocity of 50,000 h^-1. In comparison with Ce-Ti oxide catalyst, the Ce-Zr-Ti oxide catalyst showed strong resistance to H₂O and SO₂. The excellent performance of the Ce-Zr-Ti oxide catalyst might be attributed to the large surface area and strong interaction among the three elements of Ce, Zr and Ti.
