      다국어 초록 (Multilingual Abstract)

      In this study we designed a lean NOx trap (LNT) model with GT-POWER™ program and then the LNT model was compared to the bench flow reactor test results. This model consists of 9 kinetic reactions to represent the main steps of NO oxidation, NOx adsorption, NOx release and then its reduction. The comparison was performed on the operating conditions at the space velocity of 50,000 1/hr and 80,000 1/hr with the temperature range of 200°C ~ 500°C with the even spaced temperature step of 50°C. The experimental results show that the NOx conversion efficiency was enhanced by the temperature up to 350˚C and then decayed at higher temperatures. The LNT model predicts the similar trend of the NOx conversion efficiency to the experimental results below 350˚C, but overestimates above 350˚C. This overestimation comes from the higher reduction efficiency which was obtained by the different reduction gas composition such as C₃H? in the model to replace CH₄, C₂H₄ in the bench test.
