A model of NO, selective reduction by hydrocarbon (HC) was developed, which
takes into account the adsorption and desorption of HC. The model was appl
ied for predicting the performance of a De-NO, catalytic reactor, working u
nder transient conditions such as a legislative driving cycle. Diesel fuel
was used as a supplemental reductant. The behavior of HC and NO, reactions
and HC adsorption and desorption has been simulated successfully by our num
erical approach under the transient conditions of the simulated Japanese 10
-15 driving cycle. Our model is expected to optimize the design of selectiv
e diesel NO, reduction systems using a diesel fuel as a supplemental reduct
