Catalysts based on CaO/MgAl oxides were prepared by Ca(NO3)2.4H2O impregnation onto MgAl hydrotalcite followed by calcination at 600°C/0.5h. The materials were characterized by means of XRD, N2 physisorption, FEG-SEM equipped with energy-dispersive X-ray spectroscopy (EDS) and TPD of CO2. The oxide reactivities were evaluated using the model transesterification reaction between methyl acetate and...
Solid catalysts comprising Li-based oxides were prepared by LiNO 3 impregnation onto supports with different acid/base properties (SiO 2 , MgO, Al 2 O 3 and Mg(Al)O mixed oxide obtained from hydrotalcite). The materials were characterized by means of XRD, N 2 physisorption, ICP–OES, FEG-SEM and TPD of CO 2 . The oxide reactivities were evaluated using...
