Zuhairi Abdullah School of Chemical Engineering, Universiti Sains Malaysia, Engineering Campus, Penang, Malaysia H. Abdullah S. Bhatia B. Salamatinia H. Mootabadi Journal Article 2015 08 03 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<br />300-400 ºC and space time of 0.12-0.94 s. https://www.ijche.com/article_10335_40f6e633518b32939156a842c93a84be.pdf
