Abstract:
Binary composites on basis of Msingle bondAlsingle bondO (M = Sr, Ba), Msingle bondMgsingle bondO (M = Y, La), Msingle bondLasingle bondO (M = Sr, Ba) prepared by precipitation and calcined at 700–1200 °C were characterized by thermal analysis (TG–DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy of adsorbed probe molecule CDCl3 (FTIR), low temperature nitrogen adsorption and heat desorption of argon and their catalytic activity towards the transesterification reaction of rapeseed oil was studied in the flow fixed bed reactor at 200 °C and 20 atm. The phase composition, texture and surface composition of the catalysts are determined by their chemical nature and calcination temperature. The performance of the catalysts calcined at 700–750 °C diminishes in the order of Srsingle bondLasingle bondO > Basingle bondLasingle bondO > Lasingle bondMgsingle bondO ≥ Ysingle bondMgsingle bondO > Basingle bondAlsingle bondO700 > Srsingle bondAlsingle bondO700 and is in a straight correlation with the integrated intensity of absorption of surface carbonate species representing the amount of the strong basic sites on the surface of the catalysts. Thermal treatment of Msingle bondAlsingle bondO (M = Sr, Ba) catalysts at 1200 °C exerts minor influence on their performance.
