Resumo: The objective of the present work was to evaluate the composition and quality of coffee processing residues and their mixtures with charcoal fines for energy purposes. The coffee biomass, charcoal fines and mixtures (10, 20 and 30% of charcoal fines) were characterized for moisture, immediate and elemental chemical composition, gross and liquid heating value, and bulk and energy density. The inclusion of charcoal fines promoted a significant reduction in the moisture content of the coffee lignocellulosic biomass, as well as an increase in the energy properties. The treatment with 30% charcoal fines presented the best quality, reaching a higher calorific value of 19.44 MJ.Kg-1 and liquid heating value of 16.75 MJ.Kg-1, that is, an energy increase of 6 and 10%, respectively, compared to the treatment with 100% coffee waste biomass. The physicochemical characteristics of both the residues generated during coffee processing and the coal fines show good energetic properties, which make them an excellent material for use in the development of biofuels. Therefore, it is recommended to mix at least 20% of charcoal fines to enhance the energy performance of residues from coffee production.

La biomasa de café, los finos de carbón vegetal y las mezclas (10, 20 y 30% de finos de carbón vegetal) se caracterizaron en cuanto a humedad, composición química inmediata y elemental, poder calorífico bruto y líquido, y densidad aparente y energética. La inclusión de finos de carbón vegetal promovió una reducción significativa del contenido de humedad de la biomasa lignocelulósica de café, así como un aumento de las propiedades energéticas. El tratamiento con 30% de finos de carbón vegetal presentó la mejor calidad, alcanzando un mayor poder calorífico de 19,44 MJ.Kg-1 y un poder calorífico líquido de 16,75 MJ.Kg-1, es decir, un incremento energético del 6 y 10%, respectivamente, en comparación con el tratamiento con 100% de biomasa de residuos de café. Las características fisicoquímicas tanto de los residuos generados durante el procesamiento del café como de los finos de carbón muestran buenas propiedades energéticas, lo que los convierte en un excelente material para su uso en el desarrollo de biocombustibles. Por lo tanto, se recomienda mezclar al menos un 20% de finos de carbón para mejorar el rendimiento energético de los residuos de la producción de café.O objetivo do presente trabalho foi avaliar a composição e a qualidade dos resíduos do processamento de café e suas misturas com finos do carvão vegetal para fins energéticos. A biomassa do café, os finos de carvão vegetal e as misturas (10, 20 e 30% de finos de carvão vegetal) foram caracterizados quanto à umidade, composição química imediata e elementar, poder calorífico superior e líquido, e densidade a granel e energética. A inclusão de finos de carvão vegetal promoveu a redução significativa da umidade da biomassa lignocelulósica de café, assim como, o aumento das propriedades energéticas. O tratamento com 30% de finos de carvão vegetal apresentou a melhor qualidade, atingindo um poder calorífico superior de 19,44 MJ.Kg-1 e poder calorífico líquido de 16,75 MJ.Kg-1, ou seja, um aumento energético de 6 e 10 %, respectivamente, em relação ao tratamento com 100% de biomassa residual de café. As características físico-químicas tanto dos resíduos gerados durante o processamento do café quanto dos finos de carvão apresentam boas propriedades energéticas, que as transformam em um excelente material para utilização no desenvolvimento de biocombustíveis. Portanto, recomenda-se a mistura de pelo menos 20% de finos de carvão vegetal para potencializar o desempenho energético de resíduos oriundos da produção de café.Research, Society and Development2021-11-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2301210.33448/rsd-v10i15.23012Research, Society and Development; Vol. 10 No. 15; e326101523012Research, Society and Development; Vol. 10 Núm. 15; e326101523012Research, Society and Development; v. 10 n. 15; e3261015230122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/23012/20060Copyright (c) 2021 Dieimes Ribeiro Resende; Elesandra da Silva Araujo; Mário Sérgio Lorenço; Uasmim Lira Zidanes; Maria Lúcia Bianchi; Paulo Fernando Trugilho; Fábio Akira Morihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessResende, Dieimes RibeiroAraujo, Elesandra da SilvaLorenço, Mário Sérgio Zidanes, Uasmim Lira Bianchi, Maria Lúcia Trugilho, Paulo Fernando Mori, Fábio Akira 2021-12-06T10:13:53Zoai:ojs.pkp.sfu.ca:article/23012Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:00.473809Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
