Resumo: | The strong dependence on wood from species like Eucalyptus and Pinus genus, associated to the search for products of different qualities, led to studies about alternative wood for industrial use, mainly about species from the Caatinga biome and which is understudied for forest purposes. The aim of this study was to characterize chemically the wood from the species Pterogyne nitens and analyze its potential for pulp production. Three representative trees of 9 years old were harvested in an experimental plantation located in the southwest of Bahia state, the University of Vitória da Conquista Campus, and sampled five short logs at 0, 25, 50, 75 and 100% of the commercial height. Logs were transformed in chips and homogenized to obtain a representative composed sample for the total chemical analysis (cellulose, hemicelluloses, lignin, extractives and ashes content) and Kraft pulping (five cooking using different effective alkali loads to establish Kappa number 18). Pterogyne nitens wood basic density was 641 kg/m³, its chemical composition showed contents of cellulose (41.9%), hemicelluloses (24.7%), lignin (26.5%), extractives (7.3%) and ashes (0.5%). Pulping yield at Kappa number 18 was 46.4% and viscosity 1075 dm3/kg. The species did not suggest as an interesting alternative for pulp production (low cellulose content and screened yield), but very promising for application in the biomass energy area. |

O objetivo deste estudo foi caracterizar quimicamente a madeira da espécie Pterogyne nitens assim como analisar seu potencial para produção de polpa celulósica. Foram colhidas três árvores representativas de 9 anos, em um plantio experimental localizado na Universidade Estadual do Sudoeste da Bahia – Campus Vitória da Conquista, e amostradas cinco seções do fuste entre as posições 0, 25, 50, 75 e 100% da altura comercial. Os toretes foram transformados em cavacos e homogeneizados formando uma amostra composta representativa para a análise de densidade básica e composição química completa, bem como para a realização da polpação Kraft (cinco cozimentos utilizando diferentes cargas de álcali efetivo objetivando um Número Kappa 18). A densidade básica da madeira Pterogyne nitens foi de 641 kg/m³, sua composição química apresentou 41,9% de celulose, 24,7% de hemiceluloses, 26,5% de lignina, 7,3% de extrativos e 0,5% de cinzas. O rendimento do cozimento para Número Kappa 18 foi 46,4% e viscosidade 1075 dm3/kg. A espécie não se apresentou como uma alternativa interessante para a produção de polpa celulósica (baixo teor de celulose e rendimento depurado), mas bastante promissora para aplicação na área de energia da madeira.Universidade Federal de Santa Maria2019-12-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3102110.5902/1980509831021Ciência Florestal; Vol. 29 No. 4 (2019); 1490-1500Ciência Florestal; v. 29 n. 4 (2019); 1490-15001980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31021/31021Copyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessPereira, Allana Katiussya SilvaLongue Júnior, DaltonMafra Neto, Caio da SilvaColodette, Jorge LuizGomes, Fernando José Borges2019-12-10T21:30:48Zoai:ojs.pkp.sfu.ca:article/31021Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-12-10T21:30:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
