Resumo: | About 25% of CO2 emissions in the EU are originated by the transport sector. In this segment, road transport is the largest emitter, accounting for over 70% of all greenhouse gas (GHG) emissions. One of the main strategies for reducing emissions is the promotion of low emission alternative energy for transport, such as biofuels. Some alcohols and ethers, such as oxygenate additives, are added to gasoline to reduce the emission of gases that produce environmental impact. These components can be obtained from renewable or agricultural raw materials, reducing dependence on fossil sources. The thermodynamic properties of liquid blends with interest as biofuels are of great importance to the petrochemical industry, not only because of their application in new gasoline formulations but also for refining design, purification and deposition processes. This work reports experimental densities, speeds of sound, refractive indices of binary systems 2-propanol + di-isopropyl-ether (DIPE), 2-propanol + 1-hexene and di-isopropyl-ether (DIPE) + 1-hexene at the temperature of 298.15 K. Besides, the viscosity of the same binary systems at the temperatures of 293.15 K, 298.15K and 313.15K are also reported. Excess molar volumes, deviations in isentropic compressibility and deviations in speeds of sound were correlated by the Redlich-Kister polynomial. In total, 756 experimental measurements were collected and analyzed to scientifically contribute for the validation of new models and equations which could satisfactorily predict the liquid blend behavior of these compounds as biofuels. |

Nesse segmento, o transporte rodoviário é o maior emissor, respondendo por mais de 70% de todas as emissões de gases de efeito estufa. Uma das principais estratégias de redução de emissões é a promoção de energia alternativa de baixa emissão para o transporte, como os biocombustíveis. Alguns álcoois e éteres, como aditivos de oxigénio, são adicionados à gasolina para reduzir a emissão de gases que produzem impacto ambiental. Esses componentes podem ser obtidos a partir de matérias-primas renováveis ou agrícolas, reduzindo a dependência de fontes fósseis. As propriedades termodinâmicas das misturas líquidas com interesse como biocombustíveis são de grande importância para a indústria petroquímica, não apenas por sua aplicação em nova formulaçao da gasolina, mas também para o projeto dos processos de refino, purificação e deposição. Este trabalho reporta densidades experimentais, velocidades de som, índices de refração de sistemas binários 2-propanol + éter diisopropílico (DIPE), 2-propanol + 1-hexeno e éter diisopropílico (DIPE) + 1-hexeno na temperatura de 298,15 K. Além disso, é apresentada a viscosidade dos mesmos sistemas binários nas temperaturas de 293,15 K, 298,15 K e 313,15 K. Volumes molares excessivos, desvios na compressibilidade isentrópica e desvios nas velocidades do som foram correlacionados pelo polinómio de Redlich-Kister. No total, 756 medições experimentais foram coletadas e analisadas para contribuir cientificamente na validação de novos modelos e equações que possibilitem a previsão satisfatória do comportamento da mistura líquida desses compostos como biocombustíveis.Brito, PauloAguilar Romero, FernandoMuñoz Rujas, NataliaBiblioteca Digital do IPBKulik, Ana Carolina2020-12-18T15:35:09Z202020192020-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10198/22973TID:202559300enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-21T10:51:23Zoai:bibliotecadigital.ipb.pt:10198/22973Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T23:14:04.018777Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
