Effect of Si/Al ratios on the activity of H-ZSM-5 modified catalysts in the catalytic oxidation of Ethyl acetate

The objective of this work is to study the effects of Si/Al in HZSM-5 and Ag-ZSM-5 catalysts in the catalytic oxidation of ethyl acetate. Catalytic studies were carried out in a catalytic fixed bed reactor under atmospheric pressure The results show that, with an increase in the Si/Al(from 14 to 400, molar ratio), the catalytic activity decreases espasully in HZSM-5 catalysts. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM).
