Brief Study of Metal-substituted ZSM-5 -Potential Application in Methanol Production

Abstract

This article clarifies the potential of Zeolite Socony Mobil-5 (ZSM-5) substituted metals such as Copper (II) (Cu) and Iron (III) (Fe) as a catalyst in the methane oxidation reaction to methanol. The authors described the physical and chemical characteristics of modified ZSM-5 with Cu and Fe as well as the fundamental theory in predicting the reaction mechanism and performance of the catalyst active site which is crucial to producing methanol from methane. Methanol has a high economic value and supplies the essential raw materials in energy, petrochemical, pharmaceutical, and environmental industries. Therefore, it is very necessary to have this basic knowledge to increase the efficiency and effectiveness of catalyst performance and enhance the green production process. The reason behind the widely used modified ZSM-5, it was easily applied in the low and intermediates temperature range, and the structure was easy to modify according to the desired performance.

Impregnation Effect of Iron (Fe) and Cobalt (Co) on ZSM-5 Zeolite Catalyst from Rice Husk Ash and Coal Fly Ash for Methanol Synthesis

“…The difference between Si/Al ratio with the synthesis formula is normally a c b occurred due to the limitation range in SEM-EDX test, but, the ZSM-5 catalyst that was synthesized still complies with the desired range. In addition, the appearance of other elements in small amounts also indicates the presence of impurities in the catalyst which may be left over from the pre-treatment process of raw material 22,23) .

“…The area of spesific surface, m The synt-ZSM-5 was lower surface area than that of commercial one. The impurities from row material such as CFA and RHA may affect to the synthesized of ZSM-5 and could as inhibitor in zeolitization process 22,23) . ZSM-5 commercial have specific surface area is 306.686 m 2 /g, and as-synthesized ZSM-5 have specific area is 114.87 m 2 /g.…”
