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...

متن کاملStructure Analysis of CeO2-ZrO2 Mixed Oxides as Oxygen Storage Promoters in Automotive Catalysts
Oxygen storage/release (OSC) capacity is an important feature common to all three-way catalysts that enables them to efficiently remove harmful compounds such as hydrocarbons, CO and NOx in automotive exhaust gases. In this report, three types of CeO2-ZrO2 (Ce:Zr = 1:1 molar ratio) compounds with different OSC were characterized by means of XRD (X-ray diffraction) and XAFS (X-ray absorption fin...
متن کاملCatalytic production of biodiesel from corn oil by metal-mixed oxides
The present study investigates the transesterification of corn oil with methanol over two oxides of MgO and ZnO at 65 ͦC and 1 atm. These two catalysts have been prepared via a conventional co-precipitation process. As for MgO, the corresponding mixed metal nitrate solution has been mixed and heated at the presence of urea. ZnO has also been synthesized by co-precipitation of metal acetate at th...
