Resumo: The objective of this study was to evaluate the effect of the final torrefaction temperature on the energy properties of wood. It was applied four treatments with three replicates, consisting of untreated wood particles and particles torrefied at temperatures of 170, 220 and 260ºC. Better physical, chemical and thermal properties of the particles were observed as a function of the torrefaction temperature. Comparing with the control group, the particles torrefied at the highest final temperature (260ºC) showed significant differences in bulk density - from 239 to 396kg/m3; the equilibrium moisture content changed from 12.3 to 5.7%; fixed carbon content - from 13.0 to 24.8%; heating value - from 4,465 to 4,945kcal/kg; and energy density - from 882 to 1,727Mcal/m3. It was concluded that torrefaction had a positive effect on the energy properties of the wood.

Foram aplicados quatro tratamentos com três repetições constituídos por partículas de madeira não torrificadas e partículas torrificadas nas temperaturas de 170, 220 e 260 ºC. Observaram-se melhores propriedades físicas, químicas e térmicas das partículas em função da temperatura de torrefação. Comparando com a testemunha, as partículas torrificadas na temperatura final mais elevada (260 ºC) apresentaram diferenças significativas na densidade a granel - de 239 para 396 kg/m3; umidade de equilíbrio higroscópico - de 12,3 para 5,7%; teor de carbono fixo - de 13,0 para 24,8%; poder calorifico - de 4465 para 4945 kcal/kg; e densidade energética - de 882 para 1727 Mcal/m3. Concluiu-se que a torrefação apresentou um efeito positivo nas propriedades energéticas da madeira.Revista Árvore2018-01-09T11:00:38Z2018-01-09T11:00:38Z2017-11-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1806-9088http://dx.doi.org/10.1590/1806-90882017000400004http://www.locus.ufv.br/handle/123456789/16182porv. 41, n. 4, e410404, Nov. 2017Silva, Carlos Miguel Simões daVital, Benedito RochaCarneiro, Angélica de Cassia OliveiraOliveira, Aylson CostaAraújo, Solange OliveiraMagalhães, Mateus Alves deinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:26:41Zoai:locus.ufv.br:123456789/16182Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:26:41LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
