Abstract

The catalytic reduction of NO_x with hydrogen and carbon monoxide in the presence of excess oxygen was studied over Pd-based catalysts with various pillared clays (PILC) as the support. The results showed that the Ti-PILC-supported Pd catalyst gave high NO conversions and the highest N ₂ product selectivity (compared to known catalysts) at low temperatures. For example, the N₂ selectivity at 140°C was 90% for Pd/Ti-PILC catalyst while that for the Pd/TiO₂/Al ₂O₃ catalyst was 50%. The effects of feed gas composition, CO concentration and H₂O/SO₂ were also studied.
