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. |

O tratamento com 30% de finos de carvão vegetal apresentou a melhor qualidade, atingindo um poder calorífico superior de 19,44 MJ.Kg-1e 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.Universidade Federal de Itajubá (UNIFEI), Campus Itabira2022-03-15T11:55:43Z2022-03-15T11:55:43Z2021-11-20info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRESENDE, D.
