总结: | Air pollution is one of the most serious problems caused by man and affects the entire environment. The high levels of concentrations of atmospheric pollutants generated in large centers from the fleet of motor vehicles and the use of non-renewable fuels lead to harmful effects on health. Based on this, the objective of this work is to analyze the polluting gases emitted by internal combustion engines powered by diesel and biodiesel from different vegetable oils using gas chromatography. The volatile organic compounds most representative in emissions (benzene, toluene and p-xylene) and inorganic compounds (carbon monoxide and carbon dioxide) were analyzed, using as fuel: diesel, soy biodiesel, coconut, cotton, soy/ coconut, soy/cotton, coconut/soy, in the proportions of 15 and 30%, changing the engine speed in 2000, 2500 and 3500 rpm as a parameter. In the gaseous emissions of the internal combustion engine, varying the quality of the mixture, a reduction in the content of both organic and inorganic compounds was detected when the percentage of biodiesel in diesel is increased. In relation to the different types of mixtures B15 and B30, CO emissions decreased by 39%, with emphasis on coconut biodiesel and the soy/coconut mixture, in addition to a reduction of around 30% of benzene and 78% of toluene. Another important result was the reduction of these emissions at high speeds and the insignificant difference when using biodiesels from different oil sources, however, coconut and soybean oil were highlighted improving the quality of the biodiesel mixture. Thus, the higher the content of biodiesel in the mixture and the greater the rotation, there is a greater disposition of oxygen in the mixture, providing a more complete combustion reducing the emissions of these gases. When comparing biodiesels with different oil sources, the greatest reductions were seen in biodiesel with the highest content in the mixture and emphasis on coconut and soy. |

Os altos índices de concentrações de poluentes atmosféricos gerados nos grandes centros provindo da frota de veículos automotores e uso de combustíveis não renováveis levam a efeitos danosos à saúde. Com base nisto, o objetivo deste trabalho é analisar os gases poluentes emitidos por motores de combustão interna movidos a diesel e biodiesel de diferentes óleos vegetais com o uso de cromatografia gasosa. Foram analisados os compostos orgânicos voláteis mais representativos nas emissões (benzeno, tolueno e p-xileno) e compostos inorgânicos (monóxido de carbono e dióxido de carbono), empregando como combustível: diesel, biodiesel de soja , coco, algodão, soja/coco, soja/algodão, coco/soja, nas proporções de 15 e 30%, alterando como parâmetro a rotação do motor em 2000, 2500 e 3500 rpm. Nas emissões gasosas do motor de combustão interna variando a qualidade da mistura, detectou-se uma redução do teor tanto de compostos orgânicos quanto inorgânicos quando se aumenta o percentual de biodiesel no diesel. Em relação aos diferentes tipos de misturas B15 e B30, as emissões de CO diminuíram em torno de 39%, com destaque para o biodiesel de coco e da mistura soja/coco, além de reduzir em torno de 30% do benzeno e 78% do tolueno. Outro resultado importante foi a redução destas emissões em altas rotações e a diferença pouco significativa ao utilizar biodieseis de diferentes fontes oleaginosas, entretanto o óleo de coco e soja foram destaque melhorando a qualidade da mistura de biodieseis. Assim quanto maior o teor de biodiesel na mistura e maior for a rotação, tem-se uma maior disposição de oxigênio na mistura, propiciando uma combustão mais completa reduzindo as emissões destes gases. Ao comparar os biodieseis com diferentes fontes oleaginosas as maiores reduções foram verificadas no biodiesel com maior teor na mistura e destaque para o coco e a soja.Sudeste-1application/pdfapplication/pdfporUniversidade Federal FluminensePrograma de Pós-Graduação em Engenharia de BiossistemasBrasilUniversidade Federal FluminensePoluição do ArÓleos vegetaisCombustível.Recursos NaturaisCromatografia gasosa de compostos orgânicos voláteis nas emissões de motor de combustão interna movido a biodieselinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Comum do Brasil - Depositainstname:Instituto Brasileiro de Informação em Ciência e Tecnologia (Ibict)instacron:IBICTTEXTDissertação PGEB- 2019 - LAURÊNIO FERREIRA LOPES_Final_ok_assinada full.pdf.txtWritten by FormatFilter org.dspace.app.mediafilter.TikaTextExtractionFilter on 2025-06-06T20:15:51Z (GMT).Extracted texttext/plain103435https://deposita.ibict.br/bitstreams/8b5b6e54-ab86-44d3-9d5c-71ac735a8d49/download935a5af657ba857e72b814b3f518cf3dMD53falseAnonymousREADTHUMBNAILDissertação PGEB- 2019 - LAURÊNIO FERREIRA LOPES_Final_ok_assinada full.pdf.jpgWritten by FormatFilter org.dspace.app.mediafilter.PDFBoxThumbnail on 2025-06-06T20:15:51Z (GMT).Generated Thumbnailimage/jpeg2872https://deposita.ibict.br/bitstreams/fecb28c0-a8ea-41b7-a76e-ab6add8ae49c/download7ed98a0fe01cbdd8c1a3d4cbb00a65fbMD54falseAnonymousREADLICENSElicense.txtWritten by org.dspace.content.LicenseUtilstext/plain; charset=utf-81867https://deposita.ibict.br/bitstreams/d8f6f280-fd9e-4d44-a1ce-9dfaf69ca857/downloada7c148eec59885ba1ba6d14692be8465MD51falseAnonymousREADORIGINALDissertação PGEB- 2019 - LAURÊNIO FERREIRA LOPES_Final_ok_assinada full.pdf/dspace/deposita/upload/Dissertação PGEB- 2019 - LAURÊNIO FERREIRA LOPES_Final_ok_assinada full.pdfapplication/pdf2221479https://deposita.ibict.br/bitstreams/131fa54f-3ffe-414a-96d9-d1e222d4338a/downloadcc0fd9d3a90526ab6375502485dd404fMD52trueAnonymousREADdeposita/5192026-03-20T17:40:00.043599Zopen.accessoai:deposita.ibict.br:deposita/519https://deposita.ibict.brRepositório ComumPUBhttp://deposita.ibict.br/oai/requestdeposita@ibict.bropendoar:46582026-03-20T17:40Repositório Comum do Brasil - Deposita - Instituto Brasileiro de Informação em Ciência e Tecnologia (Ibict)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 |
