EXHAUST GAS PROCESSING

摘要

The invention relates to a catalytic system that comprises palladium dispersed on a substrate made of zirconium oxide ZrO2 and praseodymium oxide Pr6O11, the mass ratio between the zirconium and praseodymium oxides being from 5 to 20%. The invention is particularly adapted for processing exhaust gases having a temperature of between 120°C and 400°C, and having a carbon monoxide concentration of between 2000 and 5000 ppm.
