Simulated gasoline engine emissions

The catalyst was evaluated under simulated gasoline engine emissions for oxidising (0.9% O2) and reducing (0.6% O2) conditions close to stoichiometric. Under oxidising conditions, the catalyst displayed a CO T50 of 348-358 K, an HC T50 of 513 K and as expected no NO reduction. The CO T50 remained unaffected under reducing conditions, whereas the HC T50 increased to 583 K. Complete conversion of NOj, occurred at approximately 603 K, with a T50 of 573 K under reducing conditions. Selectivity for reduction to N2 over N2O is not known.
