Resumo: Seeking sustainable alternatives to diversify the energy matrix has become a goal to be achieved by all nations. Bambo biomass can be one of these alternatives because it is a CO2-neutral energy source with the possibility of use as a fuel in solid, liquid or gaseous form. This study aimed to evaluate the effect of age of 12 and 7 years on the chemical and energetic properties of Dendrocalamus giganteus stems. For this, the contents of total extractives, lignin, volatile materials, ash and fixed carbon were determined, in addition to the basic density, higher calorific value and energy density of the stems. Evaluations of gravimetric yield of charcoal and pirolenhoso liquor produced from the carbonization of the material were also performed. Bamboos aged 7 and 12 years showed good chemical properties for energy purposes. The values of lignin content, volatile materials, fixed carbon and ash were similar between ages. However, the net calorific value, energy density, gravimetric yield of charcoal and pyroligneous acid expanded/rose with increasing age, and the highest values were found in 12-year-old colm. The species Dendrocalamus giganteus presented physical-chemical and energetic properties and they meet the expected quality criteria for the use of this biomass to generate thermal energy.

A biomassa de bambu pode ser uma dessas alternativas por ser uma fonte de energia neutra em CO2 com a possibilidade de uso como combustível na forma sólida, líquida ou gasosa. Neste estudo objetivou-se avaliar o efeito da idade de 12 e 7 anos nas propriedades químicas e energéticas de colmos de Dendrocalamus giganteus. Para isso, foram determinados os teores de extrativos totais, de lignina, de materiais voláteis, de cinzas e de carbono fixo, além da densidade básica, poder calorífico superior e densidade energética dos colmos. Também foram realizadas as avaliações de rendimento gravimétrico do carvão vegetal e do licor pirolenhoso produzidos a partir da carbonização do material. Os bambus com 12 e 7 anos de idade apresentaram boas propriedades químicas para fins energéticos. Os valores de teor de lignina, materiais voláteis, carbono fixo e cinzas foram semelhantes entre as idades. Entretanto, o poder calorífico líquido, densidade energética, rendimento gravimétrico do carvão vegetal e ácido pirolenhoso aumentaram com o aumento da idade, e os maiores valores foram verificados para os colmos com 12 anos. A espécie Dendrocalamus giganteus apresentou propriedades físico-químicas e energéticas, e atendem aos critérios de qualidade esperados para o aproveitamento dessa biomassa para produção de energia térmica.Universidade Federal de Santa Maria2022-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6768010.5902/1980509867680Ciência Florestal; Vol. 32 No. 4 (2022); 2244-2262Ciência Florestal; v. 32 n. 4 (2022); 2244-22621980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/67680/49479https://periodicos.ufsm.br/cienciaflorestal/article/view/67680/52414Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSilva, Gustavo Vargas daFarias, Daniel Tavares deColdebella, RodrigoWacht, Wanessa Lunardi Pedrazzi, Cristiane2023-04-14T15:25:31Zoai:ojs.pkp.sfu.ca:article/67680Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-14T15:25:31Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
