CHARACTERIZATION OF BIODIESEL PREPARED FROM WASTE COOKING OIL

Increased energy consumption and the depletion of petroleum reserves have pushed up oil prices globally. Diminishing reserve is another global risk factor. ProducingBiodiesel vegetable oils animal fat by transesterification can be a considerable alternative. In this study, biodiesel produced from waste cooking method with methanol in presence HCl as catalyst. Biodiesel production begins mixing raw collected used into one pool. The mixture then settled for 8 hours at room temperature before initiating process 90oC (1% weight) methanol, while methanol: ratio 1:4. lasts 9 h under condenser. purification carried out washing product twice hot water (temperature 70°C) to remove excess reactants byproducts such alcohol, catalysts, soap glycerine, fatty acid methyl ester (FAME). resulting diesel density 3.72 kg/m (at 15oC), kinematic viscosity 8.93 mm/sec., 40oC, calorific value was 41299 kj/kg, Total number 0.111 oil, Cetane 48.95, (AV) 1.135 mg/koh Ester (EV) 178.42 mg/koh. Saponification (SV) 179.56 mg/koh, pH 5.7, Glycerol Weight 97.53 (Gw).
