“…The tree requires annual rainfall amounts between 800 and 1600 mm, average annual temperatures varying between 11 and 26°C, and light, deep, well-drained soil. Seed maturation takes 6 months, with each cone containing about 75 brown seeds [23]. Peasants have explained that the C. megalocarpus tree begins bearing nuts at 3 years and matures at about 11 years.…”

Biodiesel is currently considered as the most promising substitute for diesel fuel because of its similar properties to diesel. This study presents the use of the supercritical methanol method in the production of biodiesel from Croton megalocarpus oil. The reaction parameters such as methanol-to-oil ratio, reaction temperature and reaction time were varied to obtain the optimal reaction conditions by design of experiment, specifically, response surface methodology based on threevariable central composite design with a = 2. It has been shown that it is possible to achieve methyl ester yields as high as 74.91 % with reaction conditions such as 50:1 methanol-to-oil molar ratio, 330°C reaction temperature and a reaction period of 20 min. However, Croton-based biodiesel did not sustain higher temperatures due to decomposition of polyunsaturated methyl linoleate, which is dominant in biodiesel. Lower yields were observed when higher temperatures were used during the optimization process. The supercritical methanol method showed competitive biodiesel yields when compared with catalytic methods.

“…Moisture reacts with the catalyst during transesterification reaction which leads to soap formation [26]. Biodiesel is generally considered to be insoluble in water and it actually takes up considerably more amount of water than diesel fuel [26].…”

Abstract:It is indubitable that world energy demand is increasing drastically due to rapidly growing population and urbanization. It is not obscure that biodiesel would make a massively copious contribution to the energy demand at a time when the populace is becoming increasingly conscious of the declining reserves of fossil fuels and detrimental environmental effects it poses. There are several potential feedstocks that can be used for biodiesel production. The second generation feedstocks which are the non-edible vegetable oils could be considered as promising replacement for first generation feedstocks which are the edible vegetable oils. The usage of non-edible vegetable oil in the production of biodiesel is very significant because of the profuse demand for edible oils as food source. Moreover, first generation's feedstock costs are exorbitant to be used as fuel. However, in this study, non-edible milk bush (Thevettia peruviana) seed in which its seed is enrich with oil and can be grown in arid and semi-arid condition, on waste land, roadsides and road-dividers in expressways for beautification, environmental protection and hated by herbivorous animals, was used in biodiesel production. The oil was extracted with n-hexane using soxhlet apparatus with which ample amount (60.2%) of oil was extracted. Biodiesel was produced via trans-esterification process from the crude oil of milk bush (Thevetia peruviana) seed with methanol. The optimum condition was obtained at molar ratio 6:1 of alcohol to oil, temperature of 55°C, reaction time of 60 minutes and sodium hydroxide as the base catalyst adopted. Some fuel properties (kinematic viscosity, centane number, flash point, density, cloud point, acid value and moisture) of the biodiesel produced were determined. Results obtained for these fuel properties are 4.48 mm 2 /s, 55, 135°C, 0.866, 4, 0.1 mgKOH/g, 0.03% for kinematic viscosity at 40°C, centane number, flash point, density, cloud point, acid value and moisture content respectively. The results obtained were in agreement with ASTM D6751 and EN 14214 standards. In conclusion, it has been found that there is an immense chance to produce biodiesel from milk bush (Thevetia peruviana) seed oil and therefore it can boost the future production of biodiesel.

In this study, the influence of fatty acids of both conventional and non-conventional oils in supercritical transesterification method has been reviewed. Literature on oils such as moringa oleifera, manketti, croton megalocarpus, palm and soybean has been reviewed to establish an understanding of the supercritical transesterification that employed methanol as alcohol. This study reveals that lower yield of methyl esters is observed when higher temperatures are employed in oils that are highly dominated with polyunsaturated fatty acids, such as manketti and croton megalocarpus. And the reason is that poly-unsaturated fatty acids that are present in the oils decompose easily at higher temperatures and thus reduce the methyl esters yield.
