Resumo: | This work aimed to evaluate the effect of planting sites on the elemental chemical composition of Eucalyptus urophylla wood and the quality of its charcoal and to verify the statistical relations among the properties measured in wood and charcoal. It was used twelve 7-years old trees from E. urophylla clone from Curvelo, Itacambira and Turmalina counties located in Minas Gerais State, Brazil. The elemental chemical composition (C, H, N, S and O) of the wood and C/H and C/N relations were determined. The wood was carbonized in a laboratorial muffle furnace. It was determinate the gravimetric yields in charcoal, in pyroligneous extract and, by difference, the non-condensable gases. The apparent relative density, the higher heating value, the proximate chemical composition and the yield in fixed carbon of the charcoals were also determined. The caloric value of charcoal was influenced by its proximate chemical composition. In the wood, it was observed significant effect from site on hydrogen content and C/H relation. The location also influenced the ash content and gravimetric yields in charcoal and fixed carbon, so it is considered important to consider the effect of planting site for charcoal production from the Eucalyptus urophylla clone studied. |

Foram utilizadas doze árvores de um clone de E. urophylla, aos sete anos de idade, provenientes dos municípios de Curvelo, Itacambira e Turmalina (MG). Determinou-se a composição elementar (C, H, N, S e O) e as relações C/H e C/N da madeira. A madeira foi carbonizada em forno laboratorial tipo mufla. Foram avaliados os rendimentos gravimétricos em carvão vegetal, líquido pirolenhoso e, por diferença, os gases não condensáveis. Determinou-se também a densidade relativa aparente, o poder calorífico superior, a composição química imediata e o rendimento em carbono fixo dos carvões. O valor calórico do carvão vegetal foi influenciado por sua composição química imediata.Na madeira observou-se efeito significativo do local para o teor de hidrogênio e para a relação C/H. O local também influenciou o teor de cinzas e os rendimentos gravimétricos em carvão e carbono fixo, sendo, portanto, importante considerar o efeito do local de cultivo na produção do carvão vegetal do clone de Eucalyptus urophylla estudado.Embrapa Florestas2012-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/36310.4336/2012.pfb.32.71.277Pesquisa Florestal Brasileira; v. 32 n. 71 (2012): jul./set.; 277Pesquisa Florestal Brasileira; Vol. 32 No. 71 (2012): jul./set.; 2771983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/363/pdf_5Copyright (c) 2012 Aliny Aparecida dos Reis, Thiago de Paula Protásio, Isabel Cristina Nogueira Alves de Melo, Paulo Fernando Trugilho, Angélica de Cássia Oliveira Carneirohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessReis, Aliny Aparecida dosProtásio, Thiago de PaulaMelo, Isabel Cristina Nogueira Alves deTrugilho, Paulo FernandoCarneiro, Angélica de Cássia Oliveira2017-04-28T12:56:05Zoai:pfb.cnpf.embrapa.br/pfb:article/363Revistahttps://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 |
