Resumo: | The low diversity of forest tree species used in the formation of planted forests in Brazil, based mainly on Eucalyptus and Pinus genus, has led to study of alternative woods that show good productive potential. Thus, Pterogyne nitens species (madeira-nova), which shows good growth in Brazil's northeast region, it has aroused interest despite little research on their technological characteristics. The objective of this study was to analyze the potential of Pterogyne nitens wood for the charcoal production. Nine-year-old timbers were harvested in Vitória da Conquista town, Bahia state. The woods were fragmented and carbonized in a muffle furnace with electric heating and final temperatures of 300°C, 450°C and, 600°C. Analysis were performed of carbonization process (yield in charcoal, condensable gases and non-condensable gases), apparent density (0% moisture), friability, superior heating power and, immediate chemistry of charcoal. Based on the results, it could be concluded that the fixed carbon and superior heating value of produced charcoal increased with the increasing of the final carbonization temperature. On the other hand, the increasing of the final carbonization temperature caused a reduction in the content of volatile materials and charcoal yield. The yield of non-condensable gases and friability of charcoal increased with the elevation of final carbonization temperatures from 300ºC to 450ºC, remaining constant to higher temperatures. Finally, the final carbonization temperature of 450°C was considered optimal for carbonization of that studied wood. |

Assim, a espécie Pterogyne nitens (madeira-nova), de ocorrência e bom crescimento na região Nordeste do Brasil, tem despertado interesse apesar das poucas pesquisas sobre suas características tecnológicas. O objetivo desse estudo foi analisar o potencial da madeira Pterogyne nitens para produção de carvão vegetal. Foram colhidas árvores com 9 anos de idade em Vitória da Conquista - BA. As madeiras foram fragmentadas e carbonizadas em forno mufla, com aquecimento elétrico a temperaturas finais de 300°C, 450°C e 600°C. Foram realizadas análises dos rendimentos do processo de carbonização (rendimento em carvão vegetal, gases condensáveis e gases não condensáveis) e da densidade aparente (0% umidade), friabilidade, poder calorífico superior e química imediata do carvão vegetal. Com base nos resultados, o teor de carbono fixo e o poder calorífico superior do carvão vegetal produzido aumentou com a elevação da temperatura final de carbonização. Por outro lado, o aumento da temperatura final de carbonização proporcionou uma redução no teor de materiais voláteis e no rendimento em carvão. O rendimento em gases não condensáveis e a friabilidade do carvão aumentaram com a elevação da temperatura final de carbonização de 300°C para 450°C, permanecendo constantes para temperaturas superiores. Pelos resultados observados, a temperatura final de 450ºC foi considerada ótima para carbonização da madeira estudada.Universidade Federal de Santa Maria2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3162010.5902/1980509831620Ciência Florestal; Vol. 28 No. 1 (2018); 420-431Ciência Florestal; v. 28 n. 1 (2018); 420-4311980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31620/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessFigueiredo, Márcio Emanuel OliveiraJúnior, Dalton LonguePereira, Allana Katiussya SilvaCarneiro, Angélica de Cássia OliveiraSilva, Carlos Miguel Simões da2018-04-23T20:35:22Zoai:ojs.pkp.sfu.ca:article/31620Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-04-23T20:35:22Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
