Characterization of metal particles on supporting materials mordenite, ultra stable Y zeolita, and natural zeolit

Abstract

This research aims to prepare, characterize, and determine the metal particles of Molybdenum (Mo) and Cobalt (Co) metal on the supporting material Mordenite, Ultra Stable Y-Zeolite (USY), and Natural Zeolite (ZAA). In this research the catalysts were prepared, activated, and characterized. The bimetallic catalysts CoMo/Mordenite, CoMo/USY, CoMo/ZAA were prepared by coimpregnation method with ratio amount of Co : Mo metals 1 : 2. Activation of the catalyst included calcination and reduction. The crystallinity was characterized using X-ray diffraction (XRD), minerals present in the catalyst was analyzed using X-Ray Fluorescence (XRF). The results based on characterization, it is known that catalyst CoMo/USY shows best amount metal impregnated (Co metal content is 0.09657 mmol/g and metal content of Mo is 0.62723 mmol/g). The CoMo/Mordenite and CoMo/USY metal particles contained of CoO, MoO3, CoMoO4, Co, Mo, and CoMo. Thus CoMo/ZAA metal particles consisted of CoO, MoO3, CoMoO4, Co, Mo, CoMo. Based on the characterization of the crystal structure and the metal content it is known that the CoMo/USY was the best sample compared to CoMo/Mordenite and CoMo/ZAA.
