Biodiesel Production from a Novel Nonedible Feedstock, Soursop (Annona muricata L.) Seed Oil
Energies, 2018Co-Authors: Chia-hung Su, Hoang Nguyen, Uyen Pham, My Linh Nguyen, Horng-yi JuanAbstract:This study investigated the optimal reaction conditions for biodiesel production from soursop (Annona muricata) seeds. A high oil yield of 29.6% (w/w) could be obtained from soursop seeds. Oil extracted from soursop seeds was then converted into biodiesel through two-step transesterification process. A highest biodiesel yield of 97.02% was achieved under optimal acid-catalyzed esterification conditions (temperature: 65 °C, 1% H2SO4, reaction time: 90 min, and a methanol:oil molar ratio: 10:1) and optimal alkali-catalyzed transesterification conditions (temperature: 65 °C, reaction time: 30 min, 0.6% NaOH, and a methanol:oil molar ratio: 8:1). The properties of soursop biodiesel were determined and most were found to meet the European standard EN 14214 and American Society for Testing and Materials standard D6751. This study suggests that soursop seed oil is a promising biodiesel Feedstock and that soursop biodiesel is a viable alternative to petrodiesel.

high yield and conversion of biodiesel from a Nonedible Feedstock pongamia pinnata
Journal of Agricultural and Food Chemistry, 2010Co-Authors: Yogesh Chandra Sharma, Bhaskar Singh, John KorstadAbstract:An efficient approach has been adopted for the synthesis of biodiesel developed from karanja, a Nonedible oil Feedstock. A two-step reaction was followed for synthesis of biodiesel. Karanja oil possessing a high free fatty acid content was esterified with sulfuric acid, and the product obtained was further converted to fatty acid alkyl esters (biodiesel) by transesterification reactions. A moderate molar ratio of 6:1 (methanol/oil) was efficient for acid esterification with 1.5% v/v H2SO4 and 1 h of reaction time at 60 ± 0.5 °C, which resulted in reduction of FFA from 19.88 to 1.86 mg of KOH/g. During alkaline transesterification, 8:1 molar ratio (methanol/oil), 0.8 wt % sodium hydroxide (NaOH), 1.0 wt % sodium methoxide (CH3ONa), or 1.0 wt % potassium hydroxide (KOH) as catalyst at 60 ± 0.5 °C gave optimized yield (90−95%) and high conversion (96−100%). Optimum times for alkaline transesterification were 45 min for CH3ONa and 1 h for NaOH and KOH. Conversion of karanja oil Feedstock to its respective fat...
