This study aimed to the methyl biodiesel production by transesterification reaction via alkaline catalysis, using as a raw material alternative to soybean oil commonly used, coco-da-baía oil (Cocos nucifera L). The biodiesel was characterized as to its acidity, density, humidity, ester content, flash point, glycerol (free, total, mono-, di- and triglycerides) and maximum percentage of methanol. The oil used was characterized by acid value, saponification number, fatty acids, density and humidity. Through these results, we verified the quality of the obtained biofuel.

Biodiesel is important renewable energy that stands out mainly due to the possible reduction of oil reserves and environmental impacts intensified by the use of fossil fuels. This biofuel is produced from various oily materials, catalysts, and alcohols. Generates glycerin as a byproduct, which is used in different kinds of industries. Given the importance of the fuel and the need to integrate the theoretical content with the practical application of knowledge, this article aims to describe an experiment that can be used for teaching content such as chromatography and transesterification reaction in graduation courses. For biodiesel production were used: soybean oil, methanol, and potassium hydroxide, and analysis on paper chromatography were employed: filter paper and the solvents hexane, ethyl ether, and acetic acid as eluants. The viscosity and specific gravity of soybean oil and biodiesel were measured. With experiments, the academics observed that the transesterification reaction changes the physical-chemical properties of oil when it is converted into biodiesel and understand basic principles governing the chromatographic techniques and organic reactions.

Characterization Study

Background: Increasing environmental pollution generated by fossil fuel consumption has intensified the consumption and development of renewable fuels. Objective: Thus, the aim of this work was to investigate the use of heterogeneous catalysts (SBA-15 and Al-SBA-15) for the transesterification of soybean oil to produce biodiesel. Methods: The pore size and surface acidity of SBA-15 were modified by the addition of heterogeneous Al atoms. Samples were characterized by X-ray diffraction, Nitrogen adsorption, Scanning electron microscopy, Infrared Spectroscopy, and Thermogravimetry. Results: Results of the characterization study evidenced that a large amount of mesopore and surface acidity can significantly improve the transesterification reaction with the incorporation of aluminum into the SBA-15 framework. The best results were obtained with a 24 h reaction time and Al-SBA-15. The transesterification reaction of soybean oil with ethanol during 24 h showed in this work presented an efficient conversion of 85.5% with SBA-15 catalyst and 96.5% with the Al-SBA-15 catalyst.

The paper presents the results of long-term research on the oil productivity and chemical composition of soybean oil of the Northern ecotype varieties in the Central Non-Black Earth Region. The authors consider its possible use for biodiesel production. Experiments on growing soybeans were carried out on the experimental fi eld of Russian State Agrarian University –Moscow Timiryazev Agricultural Academy (2008-2019) on recognized ultra-early ripening varieties of the Northern ecotype Mageva, Svetlaya, Okskaya (ripeness group 000). Tests were set and the research results were analyzed using standard approved methods. It has been shown that in conditions of high latitudes (57°N), limited thermal resources of the Non-Chernozem zone of Russia (the sum of active temperatures of the growing season not exceeding 2000°С), the yield and productivity of soybeans depend on the variety and moisture supply. Over the years, the average yield of soybeans amounted to 1.94 … 2.62 t/ha, oil productivity – 388 … 544 kg/ha, oil content – 19…20%, the content of oleic and linoleic fatty acids in oil – 60%, and their output from seeds harvested – 300 kg/ha. It has been established that as soybean oil and diesel fuel have similar properties,they can be mixed by conventional methods in any proportions and form stable blends that can be stored for a long time. Experimental studies on the use of soybean oil for biodiesel production were carried out on a D-245 diesel engine (4 ChN11/12.5). The concentrations of toxic components (CO, CHx, and NOx) in the diesel exhaust gases were determined using the SAE-7532 gas analyzer. The smoke content of the exhaust gases was measured with an MK-3 Hartridge opacimeter. It has been experimentally established that the transfer of a diesel engine from diesel fuel to a blend of 80% diesel fuel and 20% lubrication oil leads to a change in the integral emissions per test cycle: nitrogen oxides in 0.81 times, carbon monoxide in 0.89 times and unburned hydrocarbons in 0.91 times, i.e. when biodiesel as used as a motor fuel in a serial diesel engine, emissions of all gaseous toxic components are reduced. The study has confi rmed the expediency of using soybeans of the Northern ecotype for biofuel production.
