Improvement of the production technology of liquid biofuel from technical fats and oils

Abstract

Because of petrol energy saving, emission standards of diesel exhaust gases hazardous substances requirement toughening, as well as carbonic oxide exhaust emission control, many countries need to find how to reduce the negative influence of heat engine over the environment. The most important operation of biodiesel technical processing from fat and oil waste were studied. The importance of keeping within the mass ratio of fat, oil, and alcohol was shown. The influence of fat and oil quality stock raw materials on the composition of biodiesel were estimated. Requirements for input raw materials were developed. A determining influence of raw material moisture on the mechanism of triglycerides transesterification in fatty acids methyl ester was shown, that, according to its operational characteristics, is close to petro-diesel fuel. The raw material free fatty acids (FFA) in conjunction with water make the process ineffective. As a result of scientific research, the technology of biodiesel production from vegetable oils and animal fats has been substantiated and its equipment support is offered. Experimental - industrial tests of mobile plants showed its possible to produce a good quality product that meets the modern operational requirements for biodiesel that could be used in engines without significant redesign. As a result of scientific research, the technology of biodiesel production from vegetable oils and animal fats has been substantiated and its equipment support was offered. A hardware-processing configuration and a layout equipment plant of mobile plant for the production of biodiesel from fats and oils were developed.
