Resumo: | The sensitization for energy issues and environmental resulting from burning fossil fuels encourage the search for materials, inputs and renewable sources of energy. The biofuel is one of these renewable sources and is produced from vegetable oils extracted from raw material such as castor (Ricinus communis). It has been investigated as a raw material due to the high oil content in the seed, the possibility of plantations in regions with water deficit and high agricultural productivity. In front of the possibility of developing a simplified process for the production of biodiesel, such as in situ transesterification, which avoids the previous separation of the oil existing in the micelle, the present work aims to evaluate the kinetic behavior of extraction from castor oil using ethanol as solvent. In this context, experimental data were obtained about the kinetic from castor oil using ethanol in several conditions of temperature, as well as, fitting mathematical models able to describe the kinetic of the system castor-oil-ethanol. The castor seed used in the work were characterized about its humidity, oil content and acidity, having been obtained 4.86 %, 43.3 % and 2.1 %, respectively. The experiments were carried out in batch using sealed Erlenmeyer flasks in a thermostatic bath with reciprocal agitation to investigate the extraction process at different temperatures (25, 35 and 45 ºC) and solid-liquid ratio equal to 0.08 (g/ml). The percentage extractions were quantified in times of 15, 30, 45, 60, 120, 180, 240, 300, 480, 600 and 1440 min. For description of kinetics extraction, the fit of three different kinetic models to the experimental data was tested, pseudo-first order (PFO), pseudo-second order (PSO) and Patricelli. From the calculation of the corrected Akaike information criterion (AICc), the PSO model was the one that best described the extraction kinetics. In this way, the results obtained in this work contribute to expand the knowledge about the extraction process of castor oil with ethanol as solvent. |

O biocombustível é uma dessas fontes renováveis e é produzido a partir de óleos vegetais extraídos de matérias primas como a mamona (Ricinus communis). Ela tem sido investigada como matéria-prima devido ao alto teor de óleo na semente, a possibilidade de plantio em regiões com déficit hídrico e à sua elevada produtividade agrícola. Diante da possibilidade de desenvolvimento de um processo simplificado para a produção de biodiesel, como o de transesterificação in situ, que evita a separação prévia do óleo presente na micela, o presente trabalho busca avaliar o comportamento cinético da extração do óleo de mamona empregando etanol como solvente. Nesse contexto, foram obtidos dados experimentais sobre a cinética da extração de óleo de mamona com etanol em diferentes condições de temperatura, bem como, ajustar modelos matemáticos capazes de descrever a cinética do sistema mamona-óleo-etanol. As sementes de mamona empregadas no trabalho foram caracterizadas acerca de sua umidade, teor de óleo e acidez, tendo sido obtido 4,86 %, 43,3 % e 2,1 %, respectivamente. Os experimentos foram realizados em batelada utilizando frascos erlenmeyer selados em banho termostático com agitação recíproca para investigar o processo de extração em diferentes temperaturas (25, 35 e 45 ºC) e razão sólido-líquido 0,08 (g/mL). As extrações percentuais foram quantificadas em tempos de 15, 30, 45, 60, 120, 180, 240, 300, 480, 600 e 1440 min. Para descrição da cinética de extração, foi testado o ajuste de três modelos cinéticos diferentes aos dados experimentais, pseudo-primeira ordem (PFO), pseudo-segunda ordem (PSO) e Patricelli. A partir do cálculo do critério de informação de Akaike corrigido (AICc) o modelo PSO foi o que melhor descreveu a cinética de extração. Deste modo, os resultados obtidos neste trabalho contribuem para ampliação dos conhecimentos acerca do processo de extração de óleo de mamona com etanol como solvente.Universidade Federal de Santa Maria2022-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/reget/article/view/6268810.5902/2236117062688Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; Vol. 24 (2020): Special Edition 10 years: Advances in environmental engineering; e16Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; v. 24 (2020): Edição Especial 10 Anos REGET: Avanços na Engenharia Ambiental; e162236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/reget/article/view/62688/pdfhttps://periodicos.ufsm.br/reget/article/view/62688/htmlCopyright (c) 2020 Revista Eletrônica em Gestão, Educação e Tecnologia Ambientalhttp://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessBoligon, Suzana DielScher, Ana CarolinaWenzel, Bruno München2022-07-28T19:09:11Zoai:ojs.pkp.sfu.ca:article/62688Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2022-07-28T19:09:11Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false |
