Chemical modification of the surface of alumina with alkaline earth metal oxides using the polymeric precursor method for catalysis application

摘要

In this study. modifications of alumina surface with of alkaline earth metal oxides vvere studied, using the polymeric precursormethod. The modified compounds were characterized by X-ray diffraction, nitrogen adsorption-desorption and scanning electronmicroscopy. The catalytical properties of these new catalysts were evaluated for the transesterification reaction of babassu oil. It isobserved that the transesterification reaction of babassu oil with methanol was successfully carried out using the modified aluminasamples.
