Abstract
In modern petrochemistry, in the conditions of increasing energy shortage and significant increase in demand for all types of fuel raw materials, saving energy resources and raw materials is an extremely urgent problem. Biodiesel is an alternative fuel used in diesel engines, made from renewable raw materials such as vegetable oils. The article discusses the process of obtaining biodiesel from grape seed oil, a waste remaining after the production of various wines and fruit juices, at Ganja Sharab-2 OJSC, an agro-industrial enterprise operating in the Western region of Azerbaijan. Oil obtained by extraction from grape seed waste was used as raw material. Biodiesel was produced from grape seed oil by transesterification using KOH as a catalyst, the reaction temperature range is 20˚C, 40˚C, 60˚C and the ratio of oil to methanol is 1:3, 1:6, 1:12 mol. When the transesterification reaction was carried out optimally at a molar ratio of oil to methanol of 1:12 and a temperature of 60˚C, the biodiesel yield increased from 60% to 100%. The composition of the resulting biodiesel was analyzed by IR spectroscopy and confirmed by peaks indicating that it was formed as a result of transesterification of vegetable oils. Various physicochemical properties of biodiesel fuel were studied in comparison with the properties of petroleum-based diesel fuel. The resulting biofuel surpasses traditional diesel fuel in both its physicochemical properties and environmental and performance characteristics. To improve the operational and environmental properties of diesel fuel, it is proposed to use biodiesel as a biological additive.
