“…However, in the context of decreasing natural resources, it would be more sensible to find non‐food oils. According to Kostić et al ., the use of plum kernels, oil‐rich by‐products, would be an interesting alternative. Moreover, studies on the composition of pomaces, by‐products resulting from juice production, indicate their possible valorization as a food supplement …”

“…Furthermore, the agro‐food industry produces about 800 000 tons of waste per year . The by‐products plum seed and plum pomace have been studied for possible valorization in biofuel and as dietary food respectively . However, to the best of our knowledge, the by‐product plum leaf has never been investigated.…”

“…For example, power of ultrasonic frequency at 400 kHz should be 10 times larger than that in 10 kHz to produce a cavitation effect in the ultrasonic‐assisted production of biodiesel. Then, cavitation effect is decreased with the increase of frequency . The frequency ranges of commonly used ultrasonic frequency are 20–40 kHz .…”

Summary Ultrasound‐assisted biodiesel production is an emerging technology that features high energy density, high conversion efficiency, and environment friendliness. This review evaluates the influence of process parameters, including ultrasonic power, ultrasonic frequency, catalyst dosage, alcohol/oil ratio, reaction temperature, reaction time, and alcohol type, on the yield of ultrasonic‐assisted production of biodiesel. Limitations associated with ultrasonic‐assisted production of biodiesel are also analyzed. Further development of this technology is explored. Copyright © 2016 John Wiley & Sons, Ltd.

“…Feedstock with high acid value cannot directly undergo alkalinecatalyzed transesterification reaction since the FFAs react with the base catalyst and bring about saponification reaction. As a consequence, it diminishes the quantity of active catalyst and biodiesel yield [3]. Due to this fact, it is necessary to lower the FFA content in oil feed-stocks before running transesterification reaction of vegetable oils for biodiesel preparation.…”

The application of heterogeneous solid acid catalysts in biodiesel production has become popular and gained significant attention over the last few years. It is since these types of catalysts hold the benefits in terms of easy separation from the product, reusability of the catalyst, high selectivity of the reaction. They are also considered sustainable and powerful particularly in organic synthesis. This work studied the use of tin(II) chloride as solid Lewis acid catalyst to promote the esterification reaction of high Free Fatty Acid (FFA) jatropha oil in continuous reactive distillation column. To obtain the optimum condition, the influences of reaction time, molar ratio of the reactant, and catalyst were investigated. It was revealed that the optimum condition was achieved at the molar ratio of methanol to FFA at 1:60, catalyst concentration of 5%, and reaction temperature of 60°C with the reaction conversion of 90%. This result was significantly superior to the identical reaction performed using batch reactor. The esterification of high FFA jatropha oil using reactive distillation in the presence of tin(II) chloride provided higher conversion than that of Amberlyst-15 heterogeneous catalyst and was comparable to that of homogenous sulfuric acid catalyst, which showed 30 and 94.71% conversion, respectively. The esterification reaction of high FFA jatropha oil was subsequently followed by transesterification reaction for the completion of the biodiesel production. Transesterification was carried out at 60 °C, molar ratio of methanol to oil of 1:6, NaOH catalyst of 1%, and reaction time of one hour. The jatropha biodiesel product resulted from this two steps process could satisfy the ASTM and Indonesian biodiesel standard in terms of ester content (97.79 %), density, and viscosity.
