Analysis of the process of obtaining methyl esters of fatty acids from waste vegetable oils
(Lviv Polytechnic Publishing House, 2015) Kukushkina, Olena; Vasylkevich, Oleksandr; Bondarenko, Sergiy; Beznosyk, Yuriy; Kyiv Politechnic Institute
The technological features of the process of obtaining the methyl esters of carboxylic acids from renewable materials were analyzed. The results showed that the waste vegetable oil can be used as raw material for biofuels production. However, to increase product yield and its quality technological scheme of obtaining the product correction is needed.
Improved technology of biodiesel fuel production from waste oils
(Lviv Politechnic Publishing House, 2017-11-12) Kukushkina, Olena; Vasylkevych, Oleksandr; Bondarenko, Sergii; Igor Sikorsky Kyiv Polytechnic Institute
The process of biodiesel fuel production from waste oil is investigated. It is identified that when processing used oil, the raw material needs aftertreatment, and the presence of free fatty acids in the oil leads to the appearance of an additional reaction The ways of improvement of technological scheme for biodiesel fuel manufacturing taking into account raw material characteristics are offered.
