Effect of alumina and zirconia as binders on the activity of Fe-BEA for NH

Jin Shi, Zihao Zhang, Mingxia Chen, Zhixiang Zhang, Wenfeng Shangguan, Shunchao Gu, Hirano Shin-ichi

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 1, doi: 10.1007/s11783-018-1012-4

Abstract: Fe-BEA catalysts are active for the NH -SCR of NO.For industrial application, a binder should be added to the Fe-BEA catalysts to make them tightly adhereThe addition of alumina and zirconia as binders to the Fe-BEA led to a different effect on NO conversionIt was found that larger iron particles were formed by the migration of parent iron particles in the Fe-BEAFor the Fe-BEA with zirconia sample, NO oxidation and storage abilities decreased due to the less iron
