Description
Summary:The article discusses the prospects for the use of biofuels as an alternative fuel, which allows reducing the dangerous impact of exhaust gases from diesel engines on the environment. The results of the analysis of the technologies used for the production of biodiesel are presented. The expediency of using a hydrodynamic mixer as a device providing the intensity of the transesterification reaction in the production of biodiesel has been substantiated. A technological scheme of a laboratory installation for the production of biodiesel has been developed. Presented are the results of laboratory studies to determine the optimal material balance of the transesterification reaction for the production of biodiesel using a plant equipped with a hydrodynamic mixer. The main indicators of the transesterification reaction (viscosity, flash point, sediment height) were determined for a unit equipped with a hydrodynamic mixer. The optimal mass ratio of the transesterification reaction has been established, which ensures the best quality indicators of the resulting biodiesel and allows evaluating the efficiency of the hydrodynamic mixer used in the installation. Recommendations are given on the ratio of vegetable oil and methanol in the production of biodiesel. The best oil/methanol ratio in terms of biodiesel yield and quality is 7.5:1. The use of traditional fuel oil mixed with biodiesel can be seen as an effective way to reduce air pollution from vehicles and to ensure compliance with the rules of international organizations.
