Abstract
An integral reactor-based kinetic model for the selective reduction of nitric oxide over Cu-Zn/ZSM-5 washcoated monolithic catalysts is reported. The active component was washcoated onto a 400 cpsi ceramic monolithic substrate at a loading of 23.6 wt. % usage 2,000 ppm iso-butane was used as the reductant. High activity without significant pressure drop was achieved at a GHSV of 16,000 h-1 . Third order polynomial satisfactorily fitted the activity versus space time data and a low activation energy of +30.3 kJ/mol was obtained. The applicability of the model was demonstrated within 300-400 ºC and space time of 0.12-0.94 s.
