“…The value (4.48 mm 2 /s) agrees well with 4.50 mm 2 /s and 4.33 mm 2 /s reported by Adebowale et al [17] and Deka et al [18] respectively, who produced methyl esters (biodiesel) from the oil of Thevetia peruviana. Also, Betiku et al [19] produced biodiesel from yellow oleander oil with kinematic viscosity value of 6.0 mm 2 /s which is slightly higher than the present study (4.48 mm 2 /s) and falls above 3.5-5.0 mm 2 /s biodiesel standard set by ASTM D6751 but falls within that of EN 14214.…”

“…It is usually expressed as mg KOH/g and is set to a maximum value of 0.5 mg KOH/g in the European standard (EN 14104) and ASTM D664. From Table 3, the acid value of TPME was determined to be 0.1 mg KOH/g which falls within the set standard and it is in agreement with the acid values 0.057 mg KOH/g, 0.20 mg KOH/g and 0.46 mg KOH/g reported by deka et al [18] adebowale et al [17] and betiku et al [19] respectively. The presence of higher acid content can cause severe corrosion in internal combustion engine and fuel supply system [25].…”

“…As shown in Table 3, the cetane number of TPME was determined to be 55.2 which is in agreement with 54.2 reported by Adebowale et al [17] and considerably lower compared to 61.5 reported by Deka et al [18]. High centane number 123.5 reported by Betiku et al [19] implies short ignition delay and fuels with low centane number tend to cause incomplete combustion as a result of increased gaseous and particulate exhaust emissions [21].…”

“…It can also be compared with that reported by Adebowale et al [17] who produced methyl esters (biodiesel) from the oil of Thevetia peruviana and the flash point was found to be 125°C which is slightly below 130°C set by ASTM D6751 and slightly above 120°C set by EN 14214 biodiesel specifications. Deka et al [18] also produced biodiesel from the oil of Thevetia peruviana with flash point 75°C that is drastically below the biodiesel specifications.…”

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.

“…We recently demonstrated that by using cocoa pod husk ash calcined at 700 • C as the catalyst, 99.3 wt % biodiesel yield could be achieved using neem oil and methanol via the transesterification process, which was optimized using RSM [5]. In Tan et al [6], waste cooking oil, methanol, and Ostrich-eggshell ash calcined at 1000 • C were used to attain 96 wt % biodiesel yield in a transesterification reaction carried out at room temperature while 96 wt % yield biodiesel was obtained from yellow oleander oil and methanol using burnt banana trunk as catalyst [7], however both studies were not optimized. In a separate study, both RSM and artificial neural network (ANN) were used to optimize the transesterification reaction of yellow oleander oil and methanol using unripe plantain peel ash calcined at 500 • C as catalyst.…”

The present work was aimed at assessing the possible use of ripe plantain fruit peel as a green-base catalyst in synthesizing Azadirachta indica oil methyl esters (AIOME). The free fatty acid content of the oil (5.81 wt %) was initially reduced to 0.90 wt % using methanol: oil at 2.19 v/v, Fe 2 (SO 4 ) 3 at 6 wt %, time of 15 min and temperature of 65 • C. The pretreated oil was converted to AIOME in a transesterification process with calcined ripe plantain peel ash (CRPPA) at 700 • C as catalyst. The process was modeled by artificial neural network and optimized using genetic algorithm. The effectiveness of the developed CRPPA is ascribable to its high K content and microstructural transformation. The reliability of the model obtained was confirmed with a high coefficient of determination (R 2 ) of 0.996 and a low mean relative percentage deviation (MRPD) of 8.10%. The best operating variables combination for the process was methanol:oil of 0.73 v/v, CRPPA of 0.65 wt % and time of 57 min while the temperature was kept constant at 65 • C with a corresponding AIOME yield of 99.2 wt %. The results of this work demonstrated the potentials of ripe plantain peels and neem oil as cheap feedstocks for biodiesel production.
