الملخص

Used cooking oil was undergoing trans-esterification reaction to produce biodiesel fuel. Method of production consisted of pretreatment steps, trans-esterification, separation, washing and drying. Trans-esterification of treated oils was studied at different operation conditions, the methanol to oil mole ratio were 6:1, 8:1, 10:1, and 12:1, at different temperature 30, 40, 50, and 60 º C, reaction time 40, 60, 80, and 120 minutes, amount of catalyst 0.5, 1, 1.5, and 2 wt.% based on oil and mixing speed 400 rpm. The maximum yield of biodiesel was 91.68 wt.% for treated oils obtained by trans-esterification reaction with 10:1 methanol to oil mole ratio, 60 º C reaction temperature, 80 minute reaction time and 0.5 wt.% of NaOH catalyst. The physical properties such as specific gravity, kinematic viscosity, acid number, flash point, pour point, and water content, were measured and compared them with American Standard Test Methods (ASTM D6751). The results of these properties for biodiesel product at (6:1, 8:1, 10:1, and 12:1 of methanol to oil mole ratio) were within the range of American Standard Test Methods (ASTM D6751).
