CHANGING THE FAT AND ACID COMPOSITION OF VEGETABLE OILS UNDER ADDITION THE MINERAL DIESEL FUEL TO THEM AND UNDER THE INFLUENCE OF ULTRASOUND
The article deals with mustard oil and radish oil as the promising alternative kinds of the biological component of diesel-mixed fuel (SGS) besides also commonly known rapeseed and false-flax oils. To estimate the feasibility of using these oils as bio-component of DST the fat and acid composition of natural and processed by the ultrasound mustard and radish oils have been examined, as well as DST in volumetric ratio with mineral diesel fuel 25:75, 50:50, 75:25, 90:10. The results of the research show that adding mineral diesel fuel to vegetable oils in different volumetric ratio, and under the impact of ultrasound with the frequency of 44 kHz on the resulting mixed fuel makes it possible to change the percentage composition of fatty acids and get a uniform and fine-disperse emulsion of oil and mineral fuel.
