Scientific and technical achievements in the development of alternative energy sources contribute to the development of biofuel technologies and are aimed at researching methods for obtaining biofuels, optimizing these processes and introducing processes into the industry of the fuel and energy complex. For the production of biofuels, all new sources of raw materials of plant or animal origin, as well as industrial and domestic waste are involved. The main goal is to find optimal conditions for the production of biofuels that meet all standards and are not inferior in terms of their physical and chemical properties to fuels from non-renewable energy sources. This final qualification work presents an analysis of existing technologies for the production of biodiesel fuel based on the use of various types of raw materials, catalyzed or non-catalyzed reactions, as well as the possibility of modeling the course of a chemical-technological process. The scientific section of the work presents the parameters of biodiesel synthesis, with a phase diagram of a three-component system being created.
