摘要：

With Na2CO3 as active component and carbon foam (CF) as carrier, solid base catalyst of Na2CO3/CF was prepared by volume impregnation method. Then, its structure and properties were characterized by SEM, SEM-EDS, FTIR, XRD, and BET. The specific surface area of the Na2CO3/CF catalyst was 182m2/g and the loaded Na2CO3 was evenly deposited on the cell wall surface of CF as fine grains with an average particle size less than 350nm. Subsequently, the catalytic activity and reusability of Na2CO3/CF were studied in the transesterification of rapeseed oil with methanol, and the process conditions were optimized. The optimal conditions were Na2CO3/CF dosage 10% (of oil weight), reaction time 180min, mole ratio of alcohol to oil 27/1, reaction temperature 65℃, and the resulting conversion was 97.80%. Moreover, the conversion still maintained 94.48% with the catalyst used for five times. The study would provide a new idea for the development of carbon-based solid base catalyst with high efficiency using the salt formed by strong base and weak acid as active center. © 2022 Chemical Industry Press.
