[ 1 ] - Immobilizing Phosphotungstic Acid on Al2O3-ZnO Nano Mixed Oxides as Heterogeneous Catalyst for Biodiesel Production by Esterification of Free Fatty Acids
In this study, esterification reaction of different carboxylic acids (Acetic acid, Palmitic acid, Oleic acid) with ethanol was investigated by ZnO, Al2O3-ZnO mixed oxide and phosphotungestic acid (10 %wt) immobilized on the Al2O3-ZnO mixed oxide. The heterogeneous catalysts were characterized by XRD, BET, FE-SEM and EDX techniques. Optimum yield was achieved by using 10% HPW/Al2O3-ZnO as the be...
