The production of biodiesel fuel from crude canola oil was evaluated in this study. The process of alkali-catalyzed transesterification with methanol was carried out to examine the effects of reaction variables on the formation of methyl ester: variables which included alcohol:oil molar ratios of 3:1, 6:1, 8:1,10:1, catalyst concentrations of 0.5, 1, 1.5, 2% w/w of oil, reaction temperatures of 30, 40, 50, 60oC, and reaction times of 10, 20, 40, 60 min. The methyl ester yield from each reaction condition is calculated. The optimum conditions for transesterification of canola oil with methanol and KOH as catalyst were found to be 50oC reaction temperature, 1 h reaction time, 8:1 molar ratio of canola oil to methanol and 1% catalyst (w/w). The resultant methyl ester content of 98%, plus all of the other measured properties of the canola biodiesel, met the international standards EN 14214.

Özet: Bu çalışmada ham kanola yağından biyodizel yakıt üretimi değerlendirilmiştir. Metanol ile, alkali katalizörlü transesterifikasyon işlemi reaksiyon değişkenlerin etkisini incelemek için gerçekleştirildi: metil ester oluşumu: alkol dahil değişkenler: : yağ mol oranları: 3: 1, 6: 1, 8: 1,10: 1, katalizör konsantrasyonu, % 0.5, 1, 1.5, 2 ağırlık / yağın ağırlığı, reaksiyon sıcaklıkları, 30, 40, 50, 60 oC ve reaksiyon süreleri 10, 20, 40, 60 dakika. Her bir reaksiyon koşulundan metil ester verimi hesaplanır. Katalizör olarak metanol ve KOH ile kanola yağı transesterifikasyonu için optimum koşullar 50 ° C reaksiyon sıcaklığı, 1 saat reaksiyon süresi, 8:1 metanole kanolanın mol oranı ve % 1 (ağırlık / ağırlık) katalizörüdür. Sonuçta % 98 metil ester içeriği ve kanola biyodizelinin diğer ölçülen tüm özellikleri, EN 14214 uluslararası standartlara uygundur.
