Description
Summary:[Display omitted] ► Catalysts MAl(La)O (M=Sr, Ba), MMgO (M=Y, La) synthesized by precipitation. ► Catalysts for rapeseed oil transesterification with methanol in flow fixed bed reactor. ► Their surfaces contain three types of basic sites strongly differing in strength. ► The activity of the catalysts increases in order SrAlOSrAlO700 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 MAlO (M=Sr, Ba) catalysts at 1200°C exerts minor influence on their performance.
