Resumo: | The global demand and production of primary energy is expected to grow at a rate of 1.4 % per year by 2035. In the same period, the production of renewable energy is expected to grow at a rate of 6.6 % per year, rising from 3 % to 9 % of world primary energy. Therefore, the biofuels supply assumes a strategic role for world energy security. In this context, sorghum is a promising alternative in the bioenergetic sector, due to its agronomic characteristics and adaptability to limiting edaphoclimatic conditions. This study aimed at evaluating the productive potential of three sorghum agronomic groups (biomass, saccharin and forage), as well as chemically characterizing the biomass of these materials. For that, a field experiment was carried out using a randomized block design, where agronomic and chemical characteristics (cellulose, hemicellulose, lignin and ash), as well as moisture contents, were evaluated. The biomass sorghum cultivars presented a high yield (about 30 t ha-1 of dry stalk), being, for this reason, more suitable for the generation of solid biofuels, i.e., direct burning. On the other hand, the forage sorghum cultivars presented a lower lignin content in the stalks, in relation to the other cultivars, being indicated for the generation of liquid biofuels. It is also worth mentioning the possibility of producing second-generation bioethanol from saccharin sorghum bagasse. Therefore, sorghum presents different use potentials that may be exploited by the bioenergy sector according to the agronomic group and plant physical part. |

No mesmo período, a produção de energias renováveis deverá crescer à taxa de 6,6 % ao ano, passando de 3 % para 9 % de energia primária mundial. Logo, a oferta de biocombustíveis assume papel estratégico para a segurança energética mundial. Neste contexto, o sorgo é uma alternativa promissora no setor bioenergético, devido às suas características agronômicas e adaptabilidade às condições edafoclimáticas limitantes. Objetivou-se avaliar o potencial produtivo de três grupos agronômicos de sorgo (biomassa, sacarino e forrageiro), bem como caracterizar quimicamente a biomassa desses materiais. Para isso, conduziu-se um experimento utilizando-se delineamento em blocos casualizados, no qual foram realizadas avaliações agronômicas, químicas (celulose, hemicelulose, lignina e cinzas) e teores de umidade. As cultivares de sorgo biomassa apresentaram alta produtividade (cerca de 30 t ha-1 de colmo seco), sendo, por isso, mais indicadas para a geração de biocombustíveis sólidos, isto é, queima direta. Já as cultivares de sorgo forrageiro apresentaram menor teor de lignina nos colmos, em relação às demais cultivares, sendo indicadas para a geração de biocombustíveis líquidos. Destaca-se, ainda, a possibilidade de produção de bioetanol de segunda geração a partir do bagaço de sorgo sacarino. Logo, o sorgo apresenta diferentes potenciais de uso que podem ser explorados pelo setor de bioenergia de acordo com o grupo agronômico e a parte física da planta.Escola de Agronomia - Universidade Federal de Goiás2018-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/49170Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 4, Oct./Dec. 2017; 424-431Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 4, out./dez. 2017; 424-431Pesquisa Agropecuária Tropical; v. 47, n. 4, out./dez. 2017; 424-4311983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/49170/25023Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessPimentel, Leonardo DuarteBatista, Vanessa Aparecida PereiraBarros, Angélica Fátima deTeófilo, Reinaldo FranciscoDias, Luiz Antônio dos Santos2020-07-13T18:52:52Zoai:ojs.revistas.ufg.br:article/49170Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T18:52:52Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false |
