摘要

A kinetic and transport model for DOCs was developed. NO2?was found to react preferentially with CO rather than C3H6. This causes NO oxidation to be inhibited. Experiments were carried out using inert washcoat layers of different thicknesses to resolve transport, kinetic and inhibition effects. The effect of washcoat transport resistance was clearest for the oxidation of C3H6?and CO. The kinetic model worked well when O, CO and NO2were the only surface species.
