“…Jurac and Zlatar [33] blended rapeseed and used frying oil in different proportion (90:10, 80:20, 70:30 and 50:50 (v/v)) and found that CP of mixed oil (50:50) biodiesel has a lower value compared to individual single oil biodiesel. Saavedra et al [34] tested several Jatropha and Palm oil combinations to produce biodiesel (percentage of Jatropha oil in the mixture were 9.1, 18.2, 28.6, 37.0, and 41.7). Jatropha oil has 19.8% saturated and 80.2% unsaturated fatty acids, while palm oil has 49% saturated and 51% unsaturated fatty acids.…”

Biodiesel's major limitations are its low-temperature performance and oxidation stability. This study analyses how different oil mixes affect biodiesel oxidation stability and cold ow. For this investigation, Jatropha, Karanja, and Palm oils were selected based on their chemical composition and availability, and their mixtures were formed. A simplex lattice mixture design model for biodiesel properties was designed, and optimisation was carried out to achieve a set of objectives. The optimal mixed-oil ratio for Jatropha, Karanja, and Palm oil was found 8:57:35(% v/v), with the desirability of 0.32, and the response values were observed to be compatible with biodiesel standards. Optimal oils mix biodiesel oxidation stability was 8.5 h, better than Jatropha (5.2 h) and Karanja (7.5 h). Similarly, blended oil's biodiesel cloud point improves by 57% compared to Palm biodiesel. oil-mixing technique balances saturated and unsaturated fatty acids and improves the oxidation stability and cold ow properties without chemical treatment.

“…In addition to adding cosolvent, another popular method is to mix two liquids more evenly, which changes the flow patterns of oil and methanol. Saavedra et al [15] used conventional alkaline and ultrasound-assisted transesterification to improve the mixing of jatropha and palm oil. The results showed that the jatropha oil optimized the fluid mixing of biodiesel.…”

Biodiesel Preparation without a Cosolvent in an Opposite-Side Micro-Fixed-Bed Reactor

In the process of preparing biodiesel using microreactors, cosolvents and homogeneous catalysts are generally used, which adds to the separation cost. Hence, this study explored the use of an opposite-side feed micro-fixed-bed reactor with an inner diameter of 2 mm to produce biodiesel by the transesterification of soybean oil and methanol without any cosolvent, in which a fixed solid base acted as catalyst and obstacles. A biodiesel yield of 99.4% was achieved when the methanol-to-oil molar ratio was 12, the temperature was 70 °C, and the residence time was 8.05 min. A mixing study was conducted for this microreactor through computational fluid dynamics (CFD) simulations. The results showed that the best mixing index could reach 0.94 within 25 mm (length). Then, the transesterification kinetics in this reactor were found to be consistent with the proposed pseudo-homogeneous secondary reaction model. With the kinetics data and mixed-model, the biodiesel yield could be predicted. The simulated results were consistent with the experimental data.
