“…The pour point referred to the lowest temperature at which there is movement of the fuel when the container is tipped. The cloud point of biodiesel from Moringa Oleifera seed oil was recorded as 16 o C. The cloud point of biodiesel produced was slightly higher [12]. This was because of high content of saturated ester which possessed higher melting point.…”

Biodiesel is a renewable energy source which is derived as an alternate fuel for diesel engine. It is produced by transesterification process. Moringa oleifera seed oil has been extracted using n-hexane by solvent extraction method. The high flashpoint of Moringa oleifera oil is a beneficial safety feature so that it can safely be stored at room temperature. The study examines the production of biodiesel using Moringa oleifera seed oil with sodium silicate as catalyst and different co-solvents. The biodiesel produced from Moringa oleifera seed oil exhibits high yield using diethyl-ether as co-solvent with 60 o C as the reaction temperature and 1 hour as the reaction time. Furthermore, the optimum ratio of methanol to oil is 7:1 and the amount of catalyst required to produce highest yield is 0.30 g. Moreover, the optimum ratio of methanol to co-solvent is 1:1 ratio. It has been found that the saponification value and free fatty acid are 170.2 mg of KOH/ g of oil and 0.33 %, respectively. The moisture content of biodiesel is 0.04% with higher calorific value when compared to diesel and vegetable oil. The pH and cloud point of biodiesel recorded are 7.37 and 18 o C, respectively. All these values have been found to be within the range of American Standard for Testing Material for biodiesel. Only the acid value has fallen outside the ASTM limits. Hence, it can be concluded that biodiesel produced from Moringa oleifera seed oil has the potential to be an alternate fuel and the energy of the future.

“…Alkali catalysts are relatively lower in cost with high biodiesel yield [9,10] while acid catalysts are more suitable for high free fatty acids (FFA) feedstocks. [11,12] Two-step acid then alkali catalysts are used for very high FFA content in the oil (up to 4%) where acid is added first then alkali transesterification is performed.…”

“…Luu et al. () used acetone as a cosolvent in the alkali‐catalyzed transesterification. This resulted in a higher reaction yield, less soap formation, and a shorter reaction time compared with the conventional alkali‐catalyzed transesterification method, but the solvents dissolved in the mixture had to be removed.…”

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.
