Abstract

This study aims to the production of biodiesel from a waste vegetable oil (WVO) using methyl alcohol and sodium hydroxide. The oil used is a mixture of soybean oil and sunflower with ratio 1:1. This oil is reminder of frying process. The study included the stirred vessel operating conditions and relative dimensions. The study was carried out under batch system using a bench scale stirred vessel. The study ended by: the ratio between the reactants; oil: alcohol: catalyst = 100 cm³: 25 cm³: 1 g, 500 rpm stirring speed and 15 min stirring time. The production is carried out under ambient temperature given that this temperature is 30^o C or more. Volume of the batch has no detectable effect on the production. The stirred vessel used for the production is without baffles.
Relating to the diameter of the vessel "D" diameter of the impeller was 1/2 D, clearance 1/5.3 D and width of impeller 1/8 D
