Pre-cleaned technical animal fats are harmful to health, as they are not environmentally friendly and not suitable for recycling. The best solution is to use them for industrial purposes, namely the conversion to biodiesel. The purpose of this study is to improve the technology for the production of biodiesel from industrial animal fats under laboratory conditions and to conduct tests on the obtained samples. The most important operations of the process of obtaining biodiesel from animal waste fats are considered. The influence of the quality of fatty raw materials on the composition of liquid biodiesel has been evaluated and initial requirements for raw materials have been developed. It has been established that the moisture content of the raw material has a decisive influence on the mechanism of the transesterification of triglycerides into fatty acid methyl esters, which, according to their performance, are close to petroleum diesel fuel. Free fatty acids in raw materials in combination with water make the process ineffective. As a result of scientific research, the technology of production of biodiesel from waste vegetable oils and animal fats has been substantiated and its hardware has been proposed. According to the results of laboratory studies, the possibility of obtaining a quality product that meets modern operational requirements for biodiesel, which can be used in engines without significant re-equipment, is established.References
