Özet
Bu tezde melastan etil alkol ve hayvansal yağlardan biyodizel üretimi araştırılmış, hayvansal yağlardan etanol yardımıyla elde edilen biyodizelin fiziksel ve kimyasal özellikleri incelenmiştir. Saccharomyces cerevisiae mayası kullanılarak şeker pancarı melasından fermantasyonla %90,69 verimle etanol üretildi. Hayvansal yağ esteri ve üretilen bu etanolün karışımlarının fiziksel özellikleri, dizel yakıtın viskozitesiyle aynı viskoziteye sahip ester/etanol karışımını bulmak için tayin edildi. Hayvansal yağ esteri ve etanolün %65:35'lik (v/v) karışımının dizel yakıtla aynı viskozite değerini verdiği gözlendi. Hayvansal yağ esteri ve etanol karışımının bir dizel yakıtı türevi olabileceği anlaşılmıştır.
In this thesis, production of ethanol from molasses and production of biodiesel from animal fats was searched. In addition, physical and chemical properties of biodiesel obtained from animal fats and bioethanol were investigated. During the investigation, ethanol was produced - with an efficiency of 90,69% - from beet molasses by means of fermentation of Saccharomyces cerevisiae yeast. The physical properties of the animal fat ester and the produced ethanol were also determined in order to confirm that the viscosity of an ester/ethanol mixture has the same value with that of diesel fuel. Then, the viscosity values of diesel fuel and animal fat ester-ethanol mixture (65:35%, v/v) were compared and it was observed that the former and the latter has the same viscosity. As a result, it has been observed that the mixture of animal fat ester and ethanol is a derivative of diesel fuel.
