Resumo: | The analysis carried out in this research had as objective the development of a process for the bench-scale production of biodiesel. The reaction was produced by the alkaline transesterification method, in which the reagents were subjected to a temperature of 60 ± 2°C, maintaining constant mechanical agitation. From a factorial experimental design, we evaluated the maximum and minimum levels of three variables: catalyst, molar ratio, and reaction time, combining their effects without altering the response quality, verifying the yields, and interpreting the possible variations based on statistical treatments to justify which one has the best performance. As the main point, two alcohols were used, one imported (methanol) that underwent a high-quality process, and another with a large national production capacity (ethanol). The research emerges as a way to reinforce the statement that biodiesel is one of the solutions to mitigate environmental impacts and socioeconomically contribute to the country. However, the production cost is higher than that of diesel derived from petroleum; thus, ensuring the best process conditions will decrease the operational costs and the costs for the end consumer. The variable with the most influence was the amount of catalyst for the synthesis of ethyl and methyl biodiesel. However, the yields for the B2 and B8 tests did not show a significant difference at the 5% level according to the Tukey test, and the highest yield was achieved by the B7 test (97.44%), using methanol at a 1:9 molar ratio and 0.5% catalyst in 90 minutes of reaction. After the research to determine the best process conditions to promote the production and use of biofuel, we concluded that the methyl route led to more satisfactory results and higher yields. |

A análise realizada nesta pesquisa teve como objetivo o desenvolvimento deum processo para a produção de biodiesel em escala de bancada. A reaçãofoi realizada pelo método de transesterificação alcalina, em que os reagentesforam submetidos à temperatura de 60 ± 2ºC mantendo constante agitaçãomecânica. Por meio de um planejamento experimental fatorial, avaliaramseos níveis máximos e mínimos de três variáveis: catalisador, razão molare tempo de reação, combinando seus efeitos sem alterar a qualidadeda resposta, verificando os rendimentos e interpretando com base nostratamentos estatísticos as possíveis variações para justificar o melhordesempenho. Como ponto principal, foram utilizados dois álcoois, um obtidomediante importação, com alta qualidade no processo; e outro, com grandecapacidade de produção nacional, metanol e etanol, respectivamente.A pesquisa surgiu como forma de aumentar o quantitativo quanto àafirmação de que o biodiesel é uma das soluções para amenizar os impactosambientais e contribuir socioeconomicamente para o país, entretanto ocusto de produção é superior ao processamento de diesel pelo petróleo.Assim, a verificação das melhores condições do processo diminuirá os custosoperacionais e para o consumidor final. A variável que mais influenciou foia quantidade de catalisador na síntese dos biodieseis etílicos e metílicos,porém os rendimentos para os ensaios B2 e B8 não apresentaram diferençasignificativa no nível de 5% pelo teste Tukey, e o maior rendimento foirealizado pelo ensaio B7 (97,44%), utilizando metanol em razão molar 1:9,0,5% de catalisador em 90 minutos de reação. Depois de pesquisas paradeterminar melhores condições de processo para promover a produção e ouso de biocombustíveis, concluiu-se que, na produção de biodiesel via rotametílica, os resultados são mais satisfatórios e os rendimentos são maiores.Zeppelini Publishers2020-06-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/60010.5327/Z2176-947820200600Revista Brasileira de Ciências Ambientais (Online); v. 55 n. 2 (2020): RBCIAMB - ISSN 2176-9478 - Junho; 226-241Brazilian Journal of Environmental Sciences (Online); Vol. 55 No. 2 (2020): RBCIAMB - ISSN 2176-9478 - June; 226-2412176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/600/527Copyright (c) 2020 Brazilian Journal of Environmental Sciences (Online)info:eu-repo/semantics/openAccessLopes, Laurênio Ferreirada Silva, Flávio CastroSimões, Rita ColmanPontual, Leandro Vahiade Souza, Luan Alvesdo Nascimento, Leomário Guedesdos Santos, Carlos Michel dos Anjos2022-03-25T22:12:11Zoai:ojs.www.rbciamb.com.br:article/600Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2022-03-25T22:12:11Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
