“…Pa.s a 20 °C e a viscosidade a 20 °C do óleo de soja é de 5,9.10 -2 Pa.s. A presença do etanol na formulação, componente de menor viscosidade, promove o aumento da região de microemulsão (Bora et al, 2015;Bora et al, 2016;Cornejo et al, 2017). A Tabela 1 mostra os valores obtidos de massa específica e viscosidade cinemática para quatro pontos diferentes da região de microemulsão do diagrama construído para a solução etanol-glicerol (50-50…”

“…Para que o biocombustível tenha viscosidade final próxima a do diesel, adicionam-se a ele outros compostos, como por exemplo, etanol. As microemulsões, quando comparadas a outros combustíveis como o diesel ou biodiesel, podem ser utilizadas para favorecer a compressão em motores a diesel, a redução das emissões de fuligem, fumaça e NO X (Qi et al, 2009;Bemert et al, 2009;Bora et al, 2015). Neste trabalho, foram construídos diagramas ternários e pseudoternário para a mistura de óleo de soja, butanol, glicerol e etanol.…”

RESUMO -O glicerol é um coproduto da produção de biodiesel que possui potencial para aplicação como combustível. Neste trabalho, glicerol foi utilizado na formulação de biocombustíveis microemulsionados. Utilizando titulação volumétrica, foram construídos diagramas ternários e pseudoternário para a mistura de óleo de soja, butanol, glicerol e etanol. A massa específica a 20 °C e a viscosidade cinemática a 40 °C de algumas formulações foram avaliadas. Nos diagramas construídos, a área da região de microemulsão diminuiu com o aumento da quantidade de glicerol. As formulações 15-75-15 (%m de óleo de soja-butanol-solução (glicerol-etanol) 50-50) e 2-53-45 apresentaram viscosidade cinemática a 40 °C de 3,6±0,2 e 4,0±0,1 mm 2 .s -1 , respectivamente.

In recent years, disposal of used cooking oil has drawn everyone attention due to its detrimental and hazardous effects upon health and environment. However, used cooking oil has great potential to be a fuel supplement after its appropriate processing for biofuel formulation, globally. Attributed to the various advantages of microemulsion-based hybrid biofuel (MHBF) technique, the present experimental investigation has focused to investigate the effects of used cooking oil (UCO)-based hybrid microemulsion biofuel (UCOMHBF), added with 2-ethylhexyl nitrate (2-EHN) (cetane enhancer) upon performance, combustion and emission characteristics of a 4-stroke single-cylinder CI engine. 2-EHN was added in UCOMHBF (UCO (55%) (vol.%), anhydrous ethanol (E) (28%) (vol.%) and 2-butanol (B) (17%)) in proportion of 500 (UCOMHBF500), 1000 (UCOMHBF1000) and 1500 (UCOMHBF1500) ppm, respectively. The brake-specific fuel consumption (BSFC) of CI engine test rig for UCOMHBF1000 was found 8% lower than UCOMHBF and B100 and 2.5% higher for UCOMHBF1500, respectively. Combustion delay was observed with MHBFs w.r.t petrodiesel, but improved combustion was observed with up to 1000 ppm addition of 2-EHN in UCOMHBF at full load condition. Addition of 1500 ppm 2-EHN in UCOMHBF showed uncontrolled flame propagation at the end of the compression stroke which resulted in incomplete combustion during power stroke. 2-EHN addition in UCOMHBF has also lowered the mean of nitrogen (NO x ) in the range of 2.06-33.33% w.r.t petrodiesel. Hence, it can be concluded that UCOMHBF1000 has shown the superior characteristics from all other UCOMHBFs.
