A global kinetic model for NOx storage and reduction on Pt/BaO/Al2O3 monolithic catalysts

A global kinetic model for NOx storage and reduction for the case of anaerobic regeneration with hydrogen is developed, based on parallel experimental studies [R.D. Clayton, M.P. Harold, V. Balakotaiah, Appl. Catal., B 84 (2008) 616; R.D. Clayton, M.P. Harold, V. Balakotaiah, C.Z. Wan, Appl. Catal., B 90 (2009) 662.]. The existence of two different types of BaO storage sites on the catalyst is proposed, which differ in their storage as well as...
