Heterogeneous catalyst screening for fatty acid methyl esters production through interesterification reaction

This study aimed the investigation of a potential heterogeneous catalyst for the interesterification reaction for soybean biodiesel production. Different types of catalysts (Y Zeolite, MgO, Nb2O5 and mixed oxides) were tested in this work. Ca–Mg–Al mixed oxide with 40% wt. Ca was the more suitable catalyst for interesterification reaction. Effects of temperature, catalyst content and methyl acetate to oil molar ratio on product yields were...
