“…The efforts conducted aim to avoid the decline of economic growth globally [1]. Renewable energies derived from plants, such as ethanol and biogas, have been used for years to obtain the standard fuels that can be applied to the engine [2,3]. Ethanol has been developed and commercialized successfully in two countries, Brazil and the United States of America, for tens of years [4,5].…”

The work was purposed to identify the compositions the blended fuel of butanol, gasoline, and water forming the stable emulsions at low temperatures. The previous researches reported that the blending of butanol and gasoline generally employed the synthetic surfactants which were expensive and mixed at room temperatures. It is important to analyze the stability of the substances in the wide range of temperature for it alter significantly on the surface of the planet. The references survey revealed that the works of the compositions of the wet butanol and gasoline at low temperatures are yet published. The present work was successful to blend the butanol, gasoline, and water in stable emulsion without using the surfactant and stabilized in the less of room temperature. Compositions of butanol, gasoline (RONs 90), and water emulsified and stabilized at low temperatures without synthetic surfactants were successfully studied. It was found that aqueous butanol and gasoline formed a stable emulsion at low temperatures and discovered the phase was separated if temperature declined. The compositions of pure butanol, gasoline, and water recorded in stable emulsions using butanol 85.00 % ranged from 75.08–79.24 %, 6.77–11.67 %, and 13.25–13.98 %, respectively, blended at temperatures 0.00–29.70 °C. The usage of butanol 99.50 % caused the change of compositions recorded at 0.71–11.34 %, 88.61–99.29 %, and 0.00–0.06 % blended at 0.00–29.00 °C. It was discovered that the increase of butanol percentage of the fuel after the emulsion was stable tended to the emulsion kept one phase. The emulsion fuels found would be applied to the heat-modified engines operating in wide range temperatures which were below room temperature

“…DESs have already found wide application in the fuel desulfurization process, management of CO 2 emissions, separation and extraction processes, and many others. The authors of refs − studied the use of DESs for the separation of mixtures containing ethanol. The authors of the review article describe in more detail various methods of using DESs in energy and fuel technologies …”

The separation of the azeotropic mixture ethanol−ethyl formate by various deep eutectic solvents (DESs) based on choline chloride was investigated. The liquid−liquid equilibria (LLE) for the systems ethanol− ethyl formate−DES were studied at 293.15 and 313.15 K and atmospheric pressure. 1 H NMR spectroscopy was used for the quantity analysis system under study. Density and dynamic viscosity were measured for the investigated DESs in the temperature range 293.15−323.15 K. The efficiency of separation of the system ethanol−ethyl formate by the DESs formed by choline chloride with various hydrogen bond donors (glycerol, urea, glutaric acid, and ethylene glycol) was evaluated by calculating the distribution coefficients and selectivity values. Dependences of the obtained selectivity values on ethanol mass fractions were discussed. A comparison of these data with the separation efficiency of other ethanol−ester systems by the same DESs was made. A correlation of experimental LLE data by the nonrandom two-liquid (NRTL) equation was carried out. Calculated data showed a good agreement with experimental compositions.

“…Como já mencionado anteriormente, a fim de facilitar os cálculos, a modelagem do DES no simulador é usualmente realizada considerando o solvente como um pseudo-componente indivisível, isto é, utilizando a abordagem de um componente pseudo-puro, apesar de ser constituído por uma mistura. Logo, A inserção das propriedades do DES no simulador foi realizada seguindo o tutorial presente no trabalhode Fontana (2021), no qual são apresentados as propriedades e o passo a passo para a inserção de todas as informações necessárias no simulador. As propriedades escalares, obtidas experimentalmente porMirza et al (2015) e apresentadas porFontana et al Fonte: FONTANA et al (2021) O equacionamento e as constantes inseridas no simulador para as propriedades dependentes da temperatura são apresentados na Tabela 9.…”

“…As constantes da propriedade entalpia de vaporização foram estimadas pelo próprio simulador. Já a constante utilizada para a pressão de vapor foi utilizada para representar um valor desprezível desta propriedade, visto que, o solvente ChCl/ureia (1:2) apresenta uma baixa pressão de vapor, podendo ser considerado não volátil.Tabela 9-Equacionamento e constantes das propriedades dependentes da temperatura do solvente DES (ChCl/ureia (1:2)) inseridas no simulador Aspen Plus rule, respectivamente(FONTANA et al, 2021). Para validar os equacionamentos e constantes utilizadas para os parâmetros dependentes da temperatura, foram gerados dados dessas propriedades no simulador Aspen Plus, e estes comparados com os dados experimentais da literatura por meio de gráficos.…”
