Resumo: | This research aimed to analyze the quality and yields of the charcoal of a Eucalyptus grandis x Eucalyptus urophylla hybrid clone commercially named GG100 for use in iron industry at different ages, plantation sites and spacing. The wood was carbonized in a laboratorial electric furnace (muffle furnace) at a heating rate of 1.67 ºC min-1 until the final temperature of 450 ºC, remaining stabilized for 30 min. The gravimetric yield in charcoal, pyroligneous extract, non condensable gases and insoluble tar, proximate and elemental chemical composition, relative apparent density and higher heating value of the charcoal were determined. In general, the charcoal evaluated may be considered homogeneous based on chemical and physical aspects and can be used in the steel sector. The apparent relative density allowed the charcoal samples differentiation produced by the same pyrolysis condition. The results obtained suggest that the density of the charcoal is highly influenced by the wood origin. It was observed that higher values of higher heating values are positively related with carbon content and negatively related with oxygen, hydrogen and nitrogen contents and with gravimetric yield in charcoal. |

A madeira foi carbonizada em um forno elétrico laboratorial (mufla), a uma taxa de aquecimento de 1,67 ºC min-1 e temperatura final de 450 ºC, permanecendo estabilizada por 30 min. Foram determinados os rendimentos gravimétricos em carvão vegetal, líquido pirolenhoso, gases não condensáveis e em alcatrão insolúvel, a composição química imediata e elementar, a densidade relativa aparente e o poder calorífico superior do carvão vegetal. De maneira geral, o carvão vegetal avaliado pode ser considerado homogêneo quanto aos aspectos físicos e químicos e pode ser utilizado para fins siderúrgicos. A densidade relativa aparente permitiu a diferenciação das amostras de carvão vegetal produzido na mesma condição de pirólise. Os resultados obtidos sugerem que a densidade do carvão vegetal é altamente influenciada pela madeira de origem. Observou-se que maiores valores de poder calorífico superior estão relacionados positivamente com o teor de carbono e negativamente com os teores de oxigênio, hidrogênio e nitrogênio e com o rendimento gravimétrico em carvão vegetal.Embrapa Florestas2012-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/35910.4336/2012.pfb.32.71.291Pesquisa Florestal Brasileira; v. 32 n. 71 (2012): jul./set.; 291Pesquisa Florestal Brasileira; Vol. 32 No. 71 (2012): jul./set.; 2911983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/359/pdf_6Copyright (c) 2012 Maíra Reis de Assis, Thiago de Paula Protásio, Claudinéia Olímpia de Assis, Paulo Fernando Trugilho, Wilma Michele Santos Santanahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAssis, Maíra Reis deProtásio, Thiago de PaulaAssis, Claudinéia Olímpia deTrugilho, Paulo FernandoSantana, Wilma Michele Santos2017-04-28T12:56:05Zoai:pfb.cnpf.embrapa.br/pfb:article/359Revistahttps://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:2017-04-28T12:56:05Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
