Simulation of NO and NO2 sorption-desorption-reduction behaviours on Pt-impregnated HPW supported on TiO2
NO and NO2 (NOx) sorption, desorption and reduction by hydrogen, carbon monoxide and/or propene were investigated on a TiO2-supported heteropolyacid, 12-tungstophosphoric acid hexahydrate (HPW), promoted by platinum. A model taking into account NOx sorption, desorption and reduction was established. Kinetic constants for NOx sorption, desorption and reduction were extracted by modelling for the investigated range of temperature (170-300 degrees C). (C) 2007 Elsevier B.V. All rights reserved.
