Com isso, a busca por novas fontes de material lignocelulosico se faz cada vez mais necessário para suprir esta alta demanda. Desse modo, este trabalho teve por objetivo avaliar a qualidade das madeiras e cascas das espécies de Astronium fraxinifolium e Enterolobium gummiferum, características do bioma Cerrado, para fins energéticos. Foram utilizados um disco de 5 cm de espessura do DAP (diâmetro a 1,3 m do solo) de três arvores das espécies em estudo, totalizando 6 amostras. Em seguida, foram divididos perpendicularmente em cunhas e retiradas as cascas. Posteriormente, foram moídos e classificados utilizando a fração retida entre as peneiras de 40 e 60 mesh e submetidos as análises do teor de cinzas e poder calorífico superior. Os teores de cinzas da casca foram superiores aos da madeira em ambas as espécies florestais. A. fraxinifolium apresentou maior teores de cinzas nas cascas e poder calorífico na madeira, com valor de 9,06 % e 4.202 kcal kg-1, respectivamente. Entretanto, tanto a madeira quanto a casca da E. gummiferum apresentaram resultados favoráveis que a potencializam para fins energéticos.Forest biomass has become an important input for the Brazilian energy matrix. Thus, the search for new sources of lignocellulosic material is increasingly necessary to meet this high demand. Thus, this work aimed to evaluate the quality of wood and bark of Astronium fraxinifolium and Enterolobium gummiferum species, characteristic of the Cerrado biome, for energy purposes. A 5 cm-thick DBH disc (diameter at 1.3 m from the ground) of three trees of the species under study was used, totaling 6 samples. Then, they were divided perpendicularly into wedges and removed as barks. Afterwards, they were ground and classified using a fraction retained between 40 and 60 mesh sieves and analysis of ash content and higher calorific value. Bark ash contents were higher than wood in both forest species. A. fraxinifolium has higher ash content in bark and higher calorific value in wood, with values of 9.06 % and 4.202 kcal kg-1, respectively. However, both the wood and the bark of E. gummiferum have favorable results, which enhance it for energy purposes.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisporUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASSimpósio De Ciências Florestais Do Espírito SantoBiomassa florestalEnergia - Fontes alternativasMadeira - QualidadeFlora dos cerradosTeor de cinzas e poder calorífico da casca e madeira de espécies do CerradoAsh and higher calorific power of bark and wood from Cerrado speciesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjectVaniele Bento dos SantosEdy Eime Pereira BaraúnaFernado ColenTalita BaldinJoão Gilberto Meza Ucella FilhoPatrick da Cruz Silvainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/53005/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALTeor de cinzas e poder calorífico da casca e madeira de espécies do cerrado.pdfTeor de cinzas e poder calorífico da casca e madeira de espécies do cerrado.pdfapplication/pdf1058511https://repositorio.ufmg.br/bitstream/1843/53005/2/Teor%20de%20cinzas%20e%20poder%20calor%c3%adfico%20da%20casca%20e%20madeira%20de%20esp%c3%a9cies%20do%20cerrado.pdf865e6b4b67660cb54b2bbd49630c5f56MD521843/530052023-05-10 16:50:06.691oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-05-10T19:50:06Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
