Heterogeneous catalyzed biodiesel production from Moringa oleifera oil

Influence of metal contaminants and antioxidant additives on storage stability of biodiesel produced from non-edible oils of Eastern Africa origin (Croton megalocarpus and Moringa oleifera oils)

“…Anwar et al [10] report the significance in nutritional value and the use of M. oleifera in medicinal activities. The most eye-catching property of biodiesel derived from M. oleifera oil is the high cetane numbers of above 60, which are among the highest reported for a biodiesel fuel [11][12][13]. The details of origin, family and climatic condition for M. oleifera have been reported elsewhere in the literature [11,14].…”

Electrochemical heavy metal detection, photocatalytic, photoluminescence, biodiesel production and antibacterial activities of Ag–ZnO nanomaterial

“…To overcome these problems, heterogeneous solid catalysts are favorable for biodiesel production and these catalysts are environmentally friendly. The main advantage of using heterogeneous catalyst is easy separation and purification of final products [51]. In the present study, simarouba oil was used M a n u s c r i p t 17 for synthesis of biodiesel using ZnO and Ag-ZnO Nps as catalysts.…”

Influence of Fatty Acid Profiles during Supercritical Transesterification of Conventional and Non-Conventional Feedstocks: A Review

“…Further increase in temperature resulted in lower yield for longer reaction time than for shorter reaction time. This is because transesterification is a reversible reaction that higher temperature with longer reaction time tends to reverse back the reaction [9,54]. Low yields at severe high temperature might be attributed by the decomposition of poly-unsaturated methyl esters and unreacted triglycerides [4,51,55].…”

“…Moringa seed has a fairly soft kernel, so the oil can be extracted by hand using a screw press. Methyl esters derived from moringa oleifera oil records high cetane numbers of above 60 which are among the highest reported for a biodiesel fuel [19,23].…”

“…It is the current method of choice employed to produce biodiesel by either the batch or continuous process, with the purpose of lowering the viscosity of oil or fat [28]. Transesterification is basically the reaction of a fat or oil triglyceride with an alcohol to form esters and glycerol [23]; a catalyst is usually used to improve the reaction rate and yield [29], and because the reaction is reversible, excess alcohol is used to shift the equilibrium to the product side [4,5,28]. When triglycerides react with alcohol, the three fatty acid chains are released from the glycerol skeleton and combine with the alcohol to form fatty acid alkyl esters with glycerol produced as a by-product.…”
