“…Although the composition of the fusel oil depends on factors such as the raw material used for its production, and the conditions of the fermentation medium (CALAM et al, 2014;AWAD, et al, 2018;EUSTÁCIO et al, 2018), the system was modeled according to the compatibility between mixtures of the literature that summarize actual compositions processed by the Brazilian sugar and alcohol sector. In this way, the fusel oil was considered as a mixture of ethanol, water, propanol, isobutanol and isoamyl alcohol (BATISTA; MEIRELLES, 2011;FERREIRA et al, 2013;CALAM et al, 2014;MAYER et al, 2015). The assertions of the aforementioned authors and of Pedroza et al (2015) were the basis for the determination of the fractions of each of these components (Table 1).…”

“…In addition, direct disposal of fusel oil into the environment is not recommended in view of this action may cause undesirable environmental impacts. Therefore, one of the concerns of the sugar-alcohol industry is to seek sustainable ways to use this by-product, which has already proved to be a potential fuel, because its calorific value is similar to that presented by other alternative fuels (FERREIRA et al, 2013;CALAM et al, 2014;EUSTÁCIO et al, 2018).…”

“…The latter being its main component, and also responsible for its great commercial appeal. This superior alcohol has a market value of approximately three times the value of fuel ethanol, and its main destination is the production of esters to be used as flavoring agents, industrial solvents and plasticizers (BATISTA; MEIRELLES, 2011;FERREIRA et al, 2013;CALAM et al, 2014;DIAS et al, 2015;MAYER et al, 2015;PEDROZA et al, 2015).…”

Fusel oil is a by-product of the process of recovering hydrated ethanol, consisting of a mixture of superior alcohols, ethanol, water, among other components. Its commercial interest is mainly due to the presence of isoamyl alcohol, one of the raw materials used in the synthesis of esters, which compounds are relevant for the chemical industry. The recovery of this superior alcohol involves unit operations based on phase equilibrium, which for multicomponent systems can be studied in software that simulates the operation of equipment, in order to present predictions of interactions between its components, reducing errors, time and costs of design. In the industrial, academic and scientific fields, there are numerous challenges regarding the design of separation processes and the monitoring of mixing effects in typical operations, and the Aspen Plus process simulation and optimization platform excels in solving these issues. The current study aims to predict the Liquid-Vapor Equilibrium of the fusel oil, which was considered as a mixture of five components, from the behavioral analysis of each of the binaries that compose it. Several models were investigated, observing the deviations of the ideality as well as the azeotrope formation. The most suitable model to describe the behavior of the studied mixture was determined with the aid of literature data for the Liquid-Vapor Equilibrium of the Isoamyl alcohol/Water binary. The results show that the Wilson modeling presented better adjustment to the experimental data, although modeling with modified Wilson also showed appreciable adjustments. TERMODINÂMICA DO EQUILÍBRIO LÍQUIDO-VAPOR DO ÓLEO FÚSEL: UM ESTUDO DE CASORESUMO O óleo fúsel é um subproduto do processo de recuperação de etanol hidratado, constituído por uma mistura de alcoóis superiores, etanol, água, dentre outros componentes. Seu interesse comercial se deve principalmente à presença do álcool isoamílico, uma das matérias-primas utilizadas na síntese de ésteres, compostos estes relevantes para a indústria química. A recuperação deste álcool superior envolve operações unitárias baseadas no equilíbrio de fases, que para sistemas multicomponentes pode ser estudada em softwares que simulam o funcionamento de equipamentos, de forma a apresentar previsões das interações entre os seus componentes, reduzindo erros, tempo e custos de projeto. No âmbito industrial, acadêmico e cientifico, existem inúmeros desafios acerca do dimensionamento de processos de separação e acompanhamento dos efeitos de mistura em operações típicas, e a plataforma de simulação e otimização de processos Aspen Plus se destaca na solução destas questões. O presente trabalho tem como objetivo prever o equilíbrio Líquido-Vapor do óleo fúsel, que foi considerado como uma mistura de cinco componentes, a partir da análise comportamental de cada um dos binários que o compõe. Foram investigadas modelagens diversas, observando os desvios da idealidade e também quanto à formação de azeótropos. O modelo mais adequado para descrever o comportamento da mi...

In this study, the effects of the use of improved fusel oil on engine performance and on exhaust emissions in a spark-ignition engine were investigated experimentally in consideration of the water, gum, and moisture content at high compression ratios according to TS EN 228 standards. In the study, a four-stroke, single-cylinder, air-cooled, spark plug ignition engine with an 8/1 compression ratio was used at three different compression ratios (8/1, 8.5/1, 9.12/1). Experiments were performed for six different ratios of fuel blends (F0, F10, F20, F30, F40, and F50) at a constant speed and different loads. The data obtained from the experiments were compared with the original operating parameters of the engine while using gasoline. According to the test results, the optimal engine performance was at a 9.12/1 compression ratio and with a F30 fuel blend. With the increase from an 8/1 to 9.12/1 compression ratio for the F30 fuel blend, the overall efficiency increased by 6.91%, and the specific fuel consumption decreased by 2.35%. The effect of the optimum fusel blend on the emissions was also examined and CO emissions were reduced by 36.82%, HC emissions were reduced by 23.07%, and NOx emissions were reduced by 15.42%, while CO2 emissions were increased by 13.88%.

publicado na web em 24/03/2017 ENZYMATIC SYNTHESIS OF ISOPENTYL CAPRYLATE USING FUSEL OIL AS FEEDSTOCK. Four commercial lipase preparations immobilized by covalent attachment on epoxy-polysiloxane-β-cyclodextrin were tested as potential biocatalysts to mediate the esterification reaction of isopentanol with caprylic acid in solvent-free medium. Among them, the immobilized lipase from Rhizopus oryzae was the most active biocatalyst, attained ester conversion higher than 80% in 24 h, being selected for subsequent tests using fusel oil as source of isopentanol. An experimental design was performed and the analysis of the results revealed that the formation of the isopentyl caprylate was strongly influenced by the variable molar ratio at 95% of confidence level. The proposed mathematical model allowed predicting that the excess of caprylic acid (molar ratio fusel oil to acid of 1:1.5) and reaction temperature of 45 °C favor the reaction to attain high ester conversion. Sensory evaluation of the flavors profile in relation to all the components involved in the reaction (caprylic acid, fusel oil and esters) showed that the formed esters had distinct aromas from the starting materials, confirming that the changes in flavors occurred before and after esterification reactions.Keywords: isopentyl caprylate; immobilized lipase; fusel oil; optimization; esterification. INTRODUÇÃOEntre os diversos subprodutos gerados pela Indústria Sucroalcooleira, o óleo fúsel apresenta amplo potencial de reaproveitamento devido sua composição rica em alcoóis superiores e elevado volume gerado (120 milhões de litros/ ano). 1Apesar do seu aproveitamento não atuar diretamente na redução do custo final do álcool, sua utilização como insumo nas indústrias de transformação certamente representa um importante passo para aumentar a eficiência global da produção industrial do etanol. Atualmente, a taxa de recuperação do óleo fúsel é de apenas 25% do total produzido no país, ou seja, 30 milhões de litros/ ano.3 Possíveis alternativas para o aproveitamento deste subproduto incluem a produção de alcoóis superiores por destilação fracionada, 4 e síntese de ésteres por via química ou biotecnológica. [5][6][7] Ésteres são componentes importantes de aromas naturais e contribuem na formação e acentuação dos aromas em diversos alimentos. 8-11Com a demanda crescente de produtos naturais, a indústria de alimentos está interessada no uso da rota biotecnológica para produção de ésteres aromatizantes.11 Desta forma, é crescente o interesse da aplicação de catalisadores bioquímicos em síntese orgânica, 8-10 entre os quais especial atenção tem sido dedicada às enzimas lipolíticas (lipases e esterases), em função da elevada atividade catalítica exibida em diversos meios não convencionais. 9,10A síntese catalisada por lipases (glicerol éster hidrolases EC 3.1.1.3) de mais de 50 ésteres de aromatizantes já foi descrita na literatura 8,11 e, em princípio, a reação pode ser conduzida em meio reacional constituído de álcool e ácido carboxílico em presença ou ausência de...
