Abstract
The paper investigated the parameters influence (reaction time, reaction temperature, NaOH catalyst concentration, oil: ethanol molar ratio) of biodiesel fuel synthesis by the transesterification reaction of sunflower oil on the product yield and key characteristics. It was established that the optimal synthesis parameters for maximizing the target product yield are the following: catalyst weight – 2.0 % of oil weight; reaction time – 1.0 hour; molar ratio oil: ethanol – 1 : 6; temperature – 45 °C. Also, from the standpoint of the biodiesel fuel physicochemical properties, the following synthesis parameters are optimal : catalyst weight – 2.0 % of oil weight; reaction time – 1.0 hour; molar ratio oil: ethanol – 1 : 12; temperature – 45 °С. It should be noted that from the stand point of using biodiesel as a commercial diesel fuels blend component, high product yield is most important. The bio-components involvement in the blend diesel fuel production will result in an average increase of the fuel pool by 20%.
