Biodiesel from zophobas morio larva oil / D. Leung in Industrial & engineering chemistry research, Vol. 51 N° 2 (Janvier 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 2 (Janvier 2012) . - pp. 1036-1040 Titre : Biodiesel from zophobas morio larva oil : Process optimization and FAME characterization Type de document : texte imprimé Auteurs : D. Leung, Auteur ; Depo Yang, Auteur ; Zhuoxue Li, Auteur Année de publication : 2012 Article en page(s) : pp. 1036-1040 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Optimization Résumé : The advancement of biodiesel production emphasizes the finding of new, low-cost, and plentiful raw materials. Insects, as one of the most plentiful biological resources worldwide, could be potential candidates for biodiesel production. In this study, Zophobas morio (Coleoptera: Tenebrionidae) was evaluated as an insect feedstock, attempting to prove the feasibility of producing qualified biodiesel. The oil content in dried Z. morio larvae was found to be 33.80 wt %. Biodiesel from Z. morio larva oil was prepared by acid esterification followed by alkaline transesterification. The parameters of the reaction were optimized at 1.25 wt % potassium hydroxide catalyst, a 5:1 methanol to oil ratio, a reaction temperature of 50 °C, and a reaction time of 45 min. Under these conditions, the maximum fatty acid methyl ester yield was 92.35 wt %. The biodiesel obtained was verified to be in compliance with the ASTM D6751 standard. This study supports the use of Z. morio larva oil as a viable and valuable raw feedstock for biodiesel production and indicates the potential use of insects as feedstock for applications in energy production.
