Honeycomb Shaped Monolithic Fe-β Zeolite Catalyst for N₂O Decomposition

Abstract:

Honeycomb shaped monolithic Fe-β zeolite catalyst for N₂O decomposition prepared by direct extrusion method was investigated. In this paper, we optimized the parameters of the molding process and studied the decomposition properties of the honeycomb catalysts. Monolithic materials could be extruded successfully only with the plasticity ranging from 0.177 to 0.473. The content of SB powder, nitrate and water was shown to have a significant influence on the mechanical strength of the extruded materials. The monolithic samples were characterized by using XRD. Catalytic performances of various monolithic zeolites with diverse density (49 cells/in.2, 81cells/in.2, 169 cells/in.2) were thereafter studied. As shown from the result, catalyst activity increased significantly with the increase of monolithic catalyst density.
