“…This composition was found slightly different from the Mexican jatropha oil which dominantly consists of 47.20% of oleic acid, 27.60% linoleic acid, and 16.09% palmitic acid [13]. However, it is comparable to the general chemical composition of jatropha oil which comprises 34.30-45.80% oleic acid, 29.00-44.20% linoleic acid, and 14.1-15.3% palmitic acid [14].…”

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.

“…Praptijanto et al. () found that use of a clamp‐on tubular reactor reduces the time required up to 96% for esterification reaction and 83% for transesterification reaction compared with the conventional stirring method. Ultrasound continually inserts energy at a slower rate, which can result in a more stable conversion scenario than other methods.…”

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.

“…Biodiesel fuel, made from vegetable oils, animal fats, or to some extent from waste cooking oils, is a viable alternative to petroleum diesel fuel [1] , [2] . It has been receiving a great deal of attention as an alternative to fossil fuels since mineral or petroleum fuel sources are depleting rapidly [3] .…”

“…Moreover, because they consist of fatty acid methyl esters (FAMEs), biodiesel fuels are safe, biodegradable, and renewable. They can either be used in pure form or in a blend with petroleum fuel in diesel engines [1] , [4] . Because biodiesel possesses fuel properties similar to petroleum diesel but with fewer pollutants, both scientific and commercial communities are giving careful consideration to biodiesel to try to overcome the issues involved with petroleum diesel [4] .…”
