Glicerina residual como agente lubrificante em óleo Diesel S10

| Resumo: | From the environmental point of view, the use of diesel fuel poses great risks to the planet, as it also produces high toxicity, such as nitrogen oxides (NOx), sulfur oxides (SOx) and carbon monoxide (CO). Sulfur and nitrogen are the directors of oil lubrication on the internal parts of the engine, it implicitly takes away an increase in the wear of some components. Biodiesel presents itself as a good alternative to diesel, coming from renewable sources, has a cleaner burning, less polluting the environment. One of the problems of Biodiesel is the strong production of glycerine, a product of low commercial value, but with good physical-chemical properties. Thus, the present study is useful the residual glycerin potential of biodiesel production, as is the case of diesel oil s10, the most common in the country, in order to improve its property of lubrication. A residual glycerin (crude) for the purification process for engine malfunction. In this study, the purification was performed in two stages, the first one was with a phosphoric, to make a separation between glycerol and salts and fatty acids (pre-purification). In the second one, the consumption of alcoholic beverages is an option that can be consumed in small quantities, coloration and odors that are still present (purification). As study samples, their physical-chemical and spectroscopic properties were evaluated. The results revealed that the purification method was efficient for an analyzed glycerin. Purified glycerine was used to add diesel at different concentrations. The High Frequency Reciprocating Rig (HFRR) Analysis showed that for a sample with 10% glycerin, there was a 12% decrease in the level of bedsores. The formation of the lubrication film has also been improved. Comparing the rheology of the samples, it can be seen that the presence of glycerine does not alter the considerable mode, the results of the components. |
