Investigation of Echinops Kebericho Mesfin Seed Oil as a Biodiesel Production feedstock: Opportunities from the wilderness / Bir Biyodizel Üretim hammadde olarak Echinops Kebericho Mesfin Tohum Yağı İncelenmesi: El değmeden gelen fırsatlar

The major energy sources of the world depend on coal, natural gasses and petroleum which are exhaustible and environmentally unfriendly. Biodiesel is a mono alkyl organic compound of long chain of fatty acids made of oil from plant oils and animal fats that make use of a catalyst and an alcohol, which may be utilized in traditional diesel engines to function as an option for petro-diesel or blended with petro-diesel to diminish emissions. Kebericho seed oil which is endemic to Ethiopia was studied with the objective of investigating as a possible raw material for biodiesel production in this work. The kebericho seed that was extracted at 40 °C exploiting n-hexane as solvent yielded 26.7 %w/w oil. The Crude kebericho seed oil was transesterified at 60 °C for 90 minutes using oil/methanol ratio of 1:6 and 1% weight of KOH as a catalyst, to supply its resultant methyl ester compound. The resultant Kebericho oil methyl ester yield was found 92%. The fatty acid profile determination was carried out using gas chromatographic analysis and Kebericho oil methyl ester showed that it had been largely composed of palmitic, stearic, linoleic, oleic and linolenic esters that are comparable to the profile of sunflower, safflower and soybean oil. The fuel properties of Kebericho oil methyl ester were determined using the international standard for pure biodiesel using ASTM standard and each of the measured Kebericho oil methyl ester fuel properties were satisfied the ASTM D6751 biodiesel standards. Results from this study have clearly suggested the capability of kebericho seed oil as a biodiesel feedstock. Besides, as kebericho is thought to be invasive in Ethiopia, such conceivable outcomes of creating biodiesel from such species could be considered as one future management option with potential noteworthy economic returns and environmental advantages. Ozet: Dunyanin baslica enerji kaynaklari tukenebilir ve cevreye dusmanca komur, dogal gaz ve petrol baglidir. Biyodizel petro-dizel ya da bir secenek olarak islev geleneksel dizel motorlarda kullanilabilen bir katalizor ve bir alkolun, yararlanabilir bitkisel yaglar ve hayvansal yaglardan yag yapilan yagli asitlerin uzun zincirli bir mono alkil organik bilesiktir emisyonlari azaltmak icin petro-dizel ile harmanlanmis. Etiyopya endemik oldugu Kebericho tohumu yagi bu calismada biyodizel uretimi icin olasi bir hammadde olarak sorusturma amaci ile calisilmistir. Cozucu olarak n-heksan istismar, 40 ° C'de ekstre edildi kebericho tohumu yagi agirlik / agirlik% 26,7 elde edildi. Bunu elde edilen metil ester bilesigini temin etmek uzere, bir katalizor olarak KOH 6 ve% 1 agirlik: Ham kebericho tohumu yagi 1 yag / metanol orani kullanilarak 90 dakika boyunca 60 ° C 'de transesterifiye edilmistir. Elde edilen Kebericho yagi metil ester verimi% 92 bulunmustur. Yagli asit profili belirleme, gaz kromatografik analizi ve Kebericho yagi metil esteri, buyuk olcude palmitik, stearik, linoleik, aycicegi, aspir ve soya yagi profili ile karsilastirilabilir olan oleik ve linoleik esterler olusan oldugunu gosterdi kullanilarak gerceklestirilmistir. Kebericho yagi metil esteri yakit ozellikleri ASTM standardini kullanarak saf biyodizel icin uluslararasi standart kullanilarak belirlendi ve olculen Kebericho yagi metil ester yakit ozelliklerinin her ASTM D6751 biyodizel standartlari memnun bulundu. Bu calismadan elde edilen sonuclar acik bir sekilde, bir besleme stoku olarak biyodizel kebericho tohumu yagi yetenegi ileri surmuslerdir. Ayrica, Etiyopya invaziv oldugu dusunulmektedir kebericho olarak, bu turlerin biyodizel olusturma gibi akla sonuclari potansiyel kayda deger ekonomik getirileri ve cevresel avantajlari ile tek gelecekteki yonetim secenegi olarak dusunulebilir.
