Özet

Waste cooking oil (WCO) is a mixture of animal fats and used vegetable oils used at high temperatures. It can be obtained at almost no cost. In this work, valorisation of WCO for biodiesel production (WCOME) besides assessing the quality of its binary and ternary blends with Euro diesel and higher alcohols of pentanol and octanol were examined. WCOME satisfied both EN 14214 and ASTM D6751 standards concerning cetane number (53.9), kinematic viscosity at 40 degrees C (3.55 mm(2)/s), density (899.9 kg/m(3)) at 20 degrees C and iodine value (106.59 g iodine/100 g). These results are attributed to the excellent degree of unsaturation (110.58). Introducing higher alcohols to biodiesel-diesel blends has further improved their densities and cold flow properties. Furthermore, spectral studies including FT-IR, UV-vis and NMR and thermoanalytical characterizations including TGA and DSC analyses were studied to assess the influence of pentanol and octanol addition into biodiesel-diesel blends. Finally brake thermal efficiency and BSFC and 3 regulated emissions of CO, THC and NOx emissions were evaluated. The current study proved the positive impact of higher alcohols addition to the blends. This study supports the ongoing research on biodiesel synthesis from waste cooking oil in Turkey.
