Simulation of NO and NO sub(2) sorption-desorption-reduction behaviours on Pt-impregnated HPW supported on TiO sub(2)

Simulation of NO and NO sub(2) sorption-desorption-reduction behaviours on Pt-impregnated HPW supported on TiO sub(2)

NO and NO sub(2) (NO sub(x)) sorption, desorption and reduction by hydrogen, carbon monoxide and/or propene were investigated on a TiO sub(2)- supported heteropolyacid, 12-tungstophosphoric acid hexahydrate (HPW), promoted by platinum. A model taking into account NO sub(x) sorption, desorption and r...

Zusammenfassung:NO and NO sub(2) (NO sub(x)) sorption, desorption and reduction by hydrogen, carbon monoxide and/or propene were investigated on a TiO sub(2)- supported heteropolyacid, 12-tungstophosphoric acid hexahydrate (HPW), promoted by platinum. A model taking into account NO sub(x) sorption, desorption and reduction was established. Kinetic constants for NO sub(x) sorption, desorption and reduction were extracted by modelling for the investigated range of temperature (170-300 degree C).
