Abstract : This research project deals with the preparation, characterization and testing of metal oxide-loaded mesoporous catalysts for preparation of dimethyl carbonate (DMC) via the gas reaction between methanol and carbon dioxide. The catalysists will be prepared by hydrothermal heating of silica hydrogels in pressure rectors especially designed and manufactured for this purpose. Loading of zirconia and ceria will be performed either through direct synthesis by mixing of their precursors with synthesis mixture ingredients or by post synthesis techniques by reaction of mesoporous silica with their metal salts and room temperature followed by thermal treatment and calcinations to form metal oxide onto the catalyst framework. The prepared catalysts will be characterized by powder X-ray diffraction (XRD) to determine the crystallinity, scanning electron microscopy (SEM) to study the morp0hology, fourier transfer infrared spectroscopy (FT-IR) to study the chemical nature and transmission electron microscopy (TEM) to get insight into the fine structure of the catalysts. Catalysts will be tested in the gas phase reaction of CO2 and methanol to produce DMC. Variable metal loadings, reaction temperatures and amounts of CO2 will be used to optimize the reaction conditions for the highest DMC yield and the highest reaction rates.
