Abstract
The modification structure of synthetic zeolite for catalyst applications in industrial processes is currently in great demand. This is because Zeolite has unique framework structural properties and does not damage easily even at high temperatures. This study investigates the effect of hierarchical treatment and impregnation of ZSM-5 using Rietveld refinement (search and match) analysis on sample diffraction patterns from X-Ray Diffraction with reference diffraction patterns (Crystallography Information File) using MAUD (Material Analysis Using Diffraction) software. The results of this analysis found that the hierarchical treatment and impregnation of the mixed metal Fe-Co on LudoxZSM-5 caused a phase change. The initial phase of LudoxZSM-5 is similar to the orthorhombic MFI type, which undergoes a phase change after the hierarchy is applied, i.e. it approaches the structure system of the MCM-68 type, which then approaches the FER type crystal phase (ZSM-35) after receiving the impregnation-calcination treatment.
