Evaluation of in‐situ and ex‐situ hybridization in the optimized transesterification of waste and pure vegetable oils

摘要: Feedstock hybridization is an effective approach to address the challenges of the non‐availability of raw materials for biodiesel production. This study explores the hybridization of used sunflower oil and linseed oil in an optimized parametric transesterification method catalyzed by a potassium‐rich ash obtained from waste banana peels. Fractions of the oils were analyzed and hybridized in the ratio 50:50, 30:70, 70:30 to obtain bi‐hybrid oils and then trans‐esterified to obtain hybridized biodiesel fuel – in‐situ hybridization. The same pattern of co‐mingling was adopted for the produced single oil biodiesel to obtain bi‐hybridized biodiesel fuels – ex‐situ hybridization. The biodiesel obtained from the two‐pathway hybridization processes was analyzed for its fuel properties and compared with the biodiesel quality standards. The optimal conditions used for both the single and in‐situ hybrid oil transesterification were a …
