Resumo: This research aimed to evaluate briquettes made from coffee husk, eucalyptus sawdust and maize harvesting residues, and the influence of post compaction interval on some properties of the briquettes. After oven drying of the biomass, the briquettes were produced in a laboratory briquetting machine at 120 ºC and 15 MPa. Bulk density and heating value of the fresh biomass were analyzed. After compaction, influence of time on moisture content, volumetric expansion an bulk density of the briquettes was analyzed. From the results, it was observed that milled coffee husk had the highest mean value of bulk density. There was no statistical difference for higher heating value among the biomass analyzed. The effect of pos compaction interval was significant on moisture content based on dry mass and bulk density for all briquettes produced. The briquettes produced from maize harvesting residues had high volumetric expansion. Considering tensile strength by diametric compression, coffee husk briquettes were more resistant. The results highlight the potential of energetic use of briquettes obtained by compaction of coffee husks.

Após a biomassa ser previamente seca em estufa, os briquetes foram produzidos em uma briquetadeira laboratorial, à temperatura de 120±5ºC e pressão de 15 MPa. Determinaram-se a densidade a granel e o poder calorífico das biomassas in natura. Após a compactação, avaliou-se a influência do tempo sobre a umidade, a expansão volumétrica e a densidade aparente dos briquetes. A partir dos resultados obtidos, pode-se observar que a casca de café moída apresentou o maior valor médio para densidade a granel. Estatisticamente, as biomassas analisadas apresentaram o mesmo poder calorífico superior. O efeito do tempo após a compactação da biomassa foi significativo para a umidade em base seca e densidade aparente para todos os briquetes produzidos. Os briquetes produzidos a partir dos resíduos da colheita do milho apresentaram acentuada expansão volumétrica. Quanto à resistência à tração por compressão diametral, os briquetes de casca de café apresentaram o maior valor. Os resultados encontrados reforçam a potencialidade de utilização energética dos briquetes oriundos da compactação da casca de café.Embrapa Florestas2011-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/28810.4336/2011.pfb.31.68.273Pesquisa Florestal Brasileira; v. 31 n. 68 (2011): out./dez., Florestas Energéticas; 273Pesquisa Florestal Brasileira; Vol. 31 No. 68 (2011): out./dez., Florestas Energéticas; 2731983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/288/227Copyright (c) 2011 Thiago de Paula Protásio, Isabel Cristina Nogueira Alves, Paulo Fernando Trugilho, Vinícius Oliveira Silva, Ana Elisa Rodarte Balizahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessProtásio, Thiago de PaulaAlves, Isabel Cristina NogueiraTrugilho, Paulo FernandoSilva, Vinícius OliveiraBaliza, Ana Elisa Rodarte2021-03-19T21:56:12Zoai:pfb.cnpf.embrapa.br/pfb:article/288Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2021-03-19T21:56:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
