Summary:

AbstractThis paper reports experimental conversion of spent vegetable oil with bio-ethanol to long chain biodiesel fuel in presence of a new developed solid K3PO4 heterogeneous catalyst. Examined catalyst was synthesized following dipping impregnation of γ-Al2O3 solid support in an aqueous solution of potassium phosphate tri-basic K3PO4. K3PO4/γ-Al2O3 catalyst samples were distinguished based on their percentage loadings of K3PO4 (CK3PO4) and averaged particle size (dp). Produced catalyst samples were characterized in terms of their textural and surface properties using nitrogen adsorption-desorption isotherms and carbon dioxide and ammonia temperature programmed desorption techniques respectively. While the liquid phase of the product was analyzed using a GC-Mass spectroscopy technique. Ethanolysis runs were carried out following surface response methodology, central composite design (CCD). Parameters including catalyst percentage loading (CK3PO4), catalyst particle size (dp) as well as catalyst reactor weight (cat) were simulated the design factors. While percentage of ethyl ester yield (EEY%) was used as design response.Experimental results revealed an optimal measured EEY% of 92% achieved at 15:1 reactants molar ratio, 70 °C reaction temperature, 1000r.min1 agitation speed, 25% percentage loading, 115 μm catalyst average particle size and 10 g/200 ml of catalyst weight in the reaction mixture. A high accuracy mathematical model was established for predicting the examined EEY% response results in terms of the above indicated operating parameters. Optimal EEY% of 95.43% was predicted under same operating conditions. The used catalyst was approved to be highly active, reliable and steady available solid heterogeneous catalyst that may promote the future of a more environmentally friendly biodiesel fuel
