Resumo: | The objective of this study was to evaluate the quality of the wood from Coffea arabica L. in different cultivars and cultivation systems, aiming for the production of charcoal and its complete combustion. Wood from three cultivation systems (natural, conventional and organic) and two cultivars (Mundo Novo and Catuaí) was used, totaling six treatments. Chemical compositions (molecular and immediate), basic density, carbon stock, heating values (higher and lower) and energy densities of the woods analyzed were evaluated. Furthermore, an energy dispersive X-ray spectroscopy was performed, as well as the thermogravimetric analysis of the wood. Wood residues from the species Coffea arabica L. presented technological properties that demonstrate its viability as an energy source, especially for cultivar Catuaí, which showed higher basic density, carbon stock and energy densities. The woods from the conventional system (cultivars Mundo Novo and Catuaí) are more suitable for complete combustion in boilers or furnaces, due to the K2O/CaO ratio. By thermogravimetric analysis, it can be stated that woods from the organic system (cultivars Mundo Novo and Catuaí) and the natural system (cultivar Mundo Novo) tend to present a higher yield in charcoal, if carbonized at low temperatures. |

Foram utilizadas madeiras provenientes de três sistemas de cultivo (natural, convencional e orgânico) e de duas cultivares (Mundo Novo e Catuaí), totalizando seis tratamentos. Foram avaliadas as composições químicas (molecular e imediata), a densidade básica, o estoque de carbono, os poderes caloríficos (superior e inferior) e as densidades energéticas das madeiras analisadas. Além disso, foi realizada a espectroscopia de energia dispersiva por raios X e a análise termogravimétrica da madeira. Os resíduos madeireiros da espécie Coffea arabica L. apresentaram propriedades tecnológicas que demonstram a sua viabilidade como fonte energética, com destaque para a cultivar Catuaí, que apresentou maior densidade básica, maior estoque de carbono e maiores densidades energéticas. As madeiras do sistema convencional (cultivares Mundo Novo e Catuaí) são mais indicadas para a combustão completa em caldeiras ou fornos devido à relação K2O/CaO. Pela análise termogravimétrica, pode-se afirmar que as madeiras do sistema orgânico (cultivares Mundo Novo e Catuaí) e do sistema Natural (cultivar Mundo Novo) tendem a apresentar maior rendimento em carvão vegetal se carbonizadas em baixas temperaturas.Editora UFLA2015-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/zipapplication/zipapplication/mswordapplication/zipapplication/ziphttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/800Coffee Science - ISSN 1984-3909; Vol. 10 No. 2 (2015); 158 - 168Coffee Science; Vol. 10 Núm. 2 (2015); 158 - 168Coffee Science; v. 10 n. 2 (2015); 158 - 1681984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/pdf_168https://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/1386https://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/1387https://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/1388https://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/1389https://coffeescience.ufla.br/index.php/Coffeescience/article/view/800/1390Copyright (c) 2015 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessda Silva Leite, Edson RubensProtásio, Thiago de Paulada Silva Rosado, Sebastião CarlosTrugilho, Paulo FernandoNapoli, Alfredo2015-06-02T14:28:49Zoai:coffeescience.ufla.br:article/800Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:50.512071Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
