Therefore, the idea of utilizing non-edible food crops and waste vegetable oils could help to overcome the major problems faced by the first generation of biodiesel feedstock. In this study, a ternary oil mixture comprises 50 vol% of waste cooking oil, 15 vol% of Jatropha curcas oil and 35 vol% of palm oil were premixed and developed into biodiesel via esterification and microwave irradiation-assisted transesterification using a modified household microwave in the presence of methanol and potassium hydroxide catalyst. The parameters affecting biodiesel yield were optimized via response surface methodology based on central composite design. The operating parameters were optimized at 0.78 wt% of catalyst concentration, 9.86:1 of methanol/oil molar ratio, 10.5 min of reaction time and 478 rpm of stirring speed with the predicted and experimental yields are at 96.81 and 96.91 %, respectively. The results indicate that the synergistic mixture of ternary oil in WJP biodiesel gives better cold flow properties as well as improves oxidation stability and cetane number. � 2022 THE AUTHORS Final 2023-05-29T09:36:05Z 2023-05-29T09:36:05Z 2022 Article 10.1016/j.aej.2022.03.040 2-s2.0-85127208167 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85127208167&doi=10.1016%2fj.aej.2022.03.040&partnerID=40&md5=acf8117f202683d86e18223d86522535 https://irepository.uniten.edu.my/handle/123456789/26660 61 12 9569 9582 All Open Access, Gold Elsevier B.V.
