solid base catalysts

Glycerolysis of rapeseed oil over several solid bases using fixed bed flow reactor has been studied. It was found that Mg-Al hydrotalcite and Al2O3supported CaO–ZnO demonstrate high activity in this reaction. The yield of monoglycerides reaches 70 % with 96 % oil conversion at 513 K. It was shown that pores size of a catalyst is an important factor of intensification of the glycerolysis process. It was found that turpentine additive decreases the reaction temperature due to higher solubility of glycerol in oil.
