Lean NOx Reduction with Oxidation of Carbon Monoxide and Hydrogen over Alumina Supported Palladium Catalyst |
| 초록 |
We present results that show Pd/Al2O3 has remarkably improved catalytic activity and stability for NOx reduction when prepared using the incipient wetness impregnation method with Al2O3 and Palladium precursor in the presence of CO and H2 at low temperatures under lean-burn conditions. The NOx conversion profile was maximal at 423 K (up to 95.2% for 250 ppm CO), at which temperature complete oxidation of H2 and CO occurred. There is a very strong synergic effect when both CO and H2 are simultaneously present in the feed. This catalyst has good selectivity towards N2 and has a window of operation going from 400 K to 530 K. |
