Resumo: This work assessed the effect of biomass composition (ash, volatile matter and fixed carbon content, carbon, hydrogen and nitrogen content, lignin, extractives and holocellulose content) on the condensable gas yield from the torrefaction of rice husk (Oryza sativa L.), jatropha seed husk (Jatropha curcas L.), elephant grass (Pennisetum purpureum Schum. var. mineiro); sugarcane bagasse (Sacharum officinarum L.) and bamboo (Bambusa vulgaris ex J.C. Wendl. var. vulgaris). Biomasses with a particle size between 0.5 mm and 1.0 mm were subjected to torrefaction process using a temperature gradient varying from 250 °C to 300 °C, for 15 min, with a heating rate of 20 °C min-1. Five trials were conducted for each biomass and solid, liquid and gas yields were obtained. The holocellulose and the volatile matter content of biomass showed a positive and significant correlation with condensable yield. The ash content showed a negative and significant correlation with condensable yield. There was no significant correlation between the elementary chemical composition and the condensable yield.

Wendl. var. vulgaris). As biomassas, com partículas entre 0,5 mm e 1,0 mm, foram submetidas à torrefação em um gradiente de temperatura variando de 250 °C a 300 °C, taxa de aquecimento de 20 °C min-1 e tempo de residência de 15 minutos. Foram realizados 5 ensaios por biomassa e obtidos os rendimentos em líquido, sólido e gás. O teor de holocelulose e o teor de voláteis das biomassas apresentaram correlação positiva e significativa com o rendimento em condensáveis. O teor de cinzas apresentou correlação negativa e significativa com o rendimento em condensáveis. Não houve correlação significativa entre a composição química elementar e o rendimento em condensáveis.Embrapa Florestas2014-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/74710.4336/2014.pfb.34.80.747Pesquisa Florestal Brasileira; v. 34 n. 80 (2014): out./dez.; 417-424Pesquisa Florestal Brasileira; Vol. 34 No. 80 (2014): out./dez.; 417-4241983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/747/399Copyright (c) 2014 Lucélia Alves Macedo, Patrick Louis Albert Rousset, Ailton Teixeira Valehttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMacedo, Lucélia AlvesRousset, Patrick Louis AlbertVale, Ailton Teixeira2017-04-28T12:49:00Zoai:pfb.cnpf.embrapa.br/pfb:article/747Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
