Numerical Analysis of Hydrocarbon Adsorption and Desorption Behavior on NOx Selective Reduction Catalysts Using Supplemental Hydrocarbon under Diesel Transient Condition 2002-01-0953
NOx reduction was estimated on various axial distributions of precious metal through a catalyst based on a numerical model of diesel NOx selective reduction by HC which takes into account the adsorption and desorption of HC. We had a qualitative agreement with the experimental results. We can obtain the behavior of distributions of adsorbed HC amount by our calculations, which we hardly obtain by experiments. This is a very useful information for a design of HC-SCR systems. We have developed a new method of optimization of diesel selective NOx reduction systems with a supplemental HC to improve the efficiency of HC-SCR.
