Eggshells ribbed tri – potassium phosphate fabricated catalyst for ethanolysis conversion of waste cooking oils to biodiesel fuel

Biodiesel is a promising green alternative fuel for compression ignition engines (C.I.E.s) made from vegetable oil or animal fat transesterification. Compared to traditional diesel fuel, biodiesel becomes vital fuel. Due high input feed and product purification costs, existing production systems offer less competitive prices than petroleum-derived diesel. Non-edible oils, such as waste cooking may be expensive virgin edible oils in the stream.Similarly, replacing conventional homogeneous catalysts with solid heterogeneous synthesis could reduce complexity of processing. This due their ease separation reaction mixture, which improves purity.The current study entails designing manufacturing solid, waste-based chemical reactions involving spent ethanolysis. The catalyst under consideration eggshell-supported tri-potassium phosphate (K3PO4). It seems worthy indicate that impregnating eggshell generate new active has never reported literature. Thus combination two substances main subject experiments. primary reaction's variables were ethanol:oil molar ratio (6:1 12:1), concentration (4-8wt%), time (1-3 hours). Like stirring speed temperature, other parameters remain constant at 600r.min−1 60oC, respectively. To ensure optimal set combination, runs conducted following 3-variable central composite design experiments (CCD). GC-mass analysis was used determine liquid phase composition.The study's findings ethanol transesterification catalyzed by eggshell-K3PO4 effective route production.The process reached peak conversion 99.9% an average (A = 9 mol Et/mol oil)”.
