Abstract
This work analyzes a new and low cost way to produce biodiesel by transesterification of wasted frying oil and soya bean oil in natura. Therefore a small plant was manufactured in which a drill was used as stirrer. The built plant used wood, steel angle brackets and threaded bars. As a stirrer, a propeller was welded to the end of a rod and this was coupled to the drill chuck. A funnel was also constructed to separate glycerol and ester, with PET, PVC, hose parts and a gate valve. The rotation of the drill was controlled by a voltage variator, in which it was mounted next to the plant. By means of transesterification, three main results were obtained: ester from recovered oil and ester from soya bean oil in natura with two different catalysts. Despite none of these had characteristics consistent with the ANP specification, the best case was a transesterification efficiency of 84%. The study was able to chart a way for further work, such as adding heat source to the plant to improve the efficiency of the reaction.
