Item Open Access Análisis por espectroscopia IR-FT de los recobrados de aceite quemado de motor y alternativa de utilización(Pontificia Universidad Católica del Ecuador Sede Ibarra, 2018-04) Anrango Ruiz, Cristhian AndrésThis research is based on the need to reduce the impact caused by engine burnt oils, which, due to their high content of heavy metals and other toxic organic substances, are classified as hazardous waste, causing great damage to natural resources. They are indispensable for living beings. In the work, the engine recovered oils are used in order to determine the presence of heavy metals that, in addition to contaminating the environment, decrease the quality of the product obtained from successive distillations (fractional distillation) of the engine burnt oil. These recoveries are also used for the identification of organic compounds using FTIR techniques that have characteristics similar to virgin motor oils and commercial fuels, so that they can be reused, either as new oils or as fuels. The results of the simulated distillation processes were obtained (81%) and the fractionated (87%) of the engine burned oil. The quantification of heavy metals was carried out by flame atomic absorption spectrometry. The concentrations present in burnt motor oils are in Lead (29ppm), Copper (29ppm) and Chrome (9.7ppm). Once obtained the recoveries of the burnt motor oil it can be observed that there is a decrease of the metals present in lead of 31.45% (from 29 to 19.88 ppm), Copper 99.86% (from 29 to 0.040 ppm) and Chrome 92% (from 9.7 to 0.77ppm), finding that their values are below the standards established to be used as fuel. The identification of organic components, similar to virgin motor oils and commercial fuels, was performed by Infrared Spectroscopy with Fourier Transforms (FT IR), demonstrating that the recovered oil features similar to commercial motor oils, n-hexane and diesel.
