This study explores the potential of using blended feedstock consisting of inedible jatropha oil (JO) and waste cooking oil (WO) for biodiesel production. Prior to blending, the unfavourable high acid value of jatropha oil was esterified under the most optimal conditions of 60 �C, 1% H2SO4 catalyst and alcohol to oil molar ratio of 11:1 to maximise the esterified yield (81.1 %). Based on the acid value measurement, the optimum volumetric blend of WO/EJO was determined to be 90/10 with the lowest acid value of 1.9 mg KOH g?1, which was then utilised as feedstock for base-catalysed transesterification. The KOH catalysed transesterification was optimised at 60 �C, 1 wt% KOH catalyst and alcohol to oil molar ratio of 6:1 to produce biodiesel with low acid value (0.2 mg KOH g?1), high calorific value (38.4 MJ kg?1), high oxidation stability (?11 h) and favourable viscosity (4.7 mm2 s?1). The results show that the produced biodiesel has acceptable physicochemical properties but its properties can further be improved by blending with petroleum diesel and antioxidant. Among those produced blend derivatives, petroleum diesel and biodiesel blend (80:20) or B20 showed the best improvement with high calorific value (46.6 MJ/kg), high oxidation stability (?37 h) and low acid value (0.3 mg KOH g?1). Based on the study, in situ feedstock blending of WO/EJO can improve the physicochemical properties of the produced biodiesel and reduce the dependency on single feedstock. Biodiesel blending with commercial diesel can enhance the biodiesel fuel properties and such derivatives can be directly applied in an existing engine. � 2022 Elsevier Ltd Final 2023-05-29T09:37:39Z 2023-05-29T09:37:39Z 2022 Article 10.1016/j.fuel.2022.123178 2-s2.0-85122622027 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85122622027&doi=10.1016%2fj.fuel.2022.123178&partnerID=40&md5=03e1d1b4f69169d6b62d7aac7cac1796 https://irepository.uniten.edu.my/handle/123456789/26901 315 123178 Elsevier Ltd Scopus |
