A series of additives based on Fe(III)-modified MFI, FAU, and FER zeolites were investigated with focus on their efficiency in reducing NOx in cracking catalyst regeneration flue gases. The zeolite efficiency was found to depend on the zeolite framework type and the modification method. The Fe/MFI additives exhibited excellent performance. The additives prepared by ion exchange—and distinguished by uniform distribution of highly active metal ions (Fe3+)—reached a NOx reduction efficiency of 45.4%.
