Effects of calcination temperature of eggshell-derived CaO as a catalyst for biodiesel production from waste cooking oil

Biodiesel is considered to be more friendly the environment than petroleum-based fuels, cheaper and capable for producing greener energy which contributed positively in boosting bio-economy. In this work, waste cooking oil (WCO) converted into biodiesel utilizing a eggshell (CaO) nano-catalyst an effort discover environmentally beneficial economically viable processes social economic development. The eggshell-based CaO catalyst developed production of ecologically at reduced price calcined temperatures between 600 1100 °C. synthesized catalysts were assessed terms their physical chemical qualities via BET, TGA XRD analysis. This revealed that, besides displaying exceptional transesterification activity, synthesised 950 °C also offered greatest yield. Transesterification, used generation, was evaluate catalytic performance manufactured under several reaction circumstances. Under prime conditions i.e., time 3 hours, ethanol-oil molar ratio 9:1, amount 4 wt.%, it ascertained that had demonstrated excellent activity delivered ceiling yield 88% fatty acid ethyl esters. FAME confirmed by using gas chromatography-mass spectroscopy (GC-MS). Fuel properties ester complied with ASTM D 6751 indicated would appropriate alternative form fuel.
