Resumo: | The briquetting process consists of lignocellulosic residues densification in solid biofuel with high calorific value denominated briquette. Coffee crop is one of the most important Brazilian commodities and according to the cultural practices produces plant residues in different amounts. The zero harvest system in coffee crop is based in pruning of plagiotropic branches in alternated years to make possible to concentrate the harvest and to avoid coffee biannual production. The aim of the present work was to verify the viability of briquette production using the biomass waste obtained by zero harvest system. The treatments were composed of briquetting process: 1) coffee rind; 2) mixture of branches and leaves; 3) 25% of coffee rind + 75% of branches and leaves; 4) 75% of coffee rind + 25% of branches and leaves; 5) 50% of coffee rind + 50% of branches and leaves; 6) 40% of coffee rind + 60% of branches and leaves. The mixtures were realized in v/v base, milled to produce 5-10 mm particles and were briqueted with 12% of humidity. The C-teor of briquettes produced ranged from 41.85 to 43. 84% and sulphur teor was below 0.1%. The calorific value of briquettes produced ranged from 3,359 to 4, 028 Kcal/ kg and the ashes were below 6%. The isolated use of coffee rind or branches and leaves, as well the mixtures of coffee rind with 50% or more of branches and leaves allow the production of briquettes with calorific value around 4,000 Kcal/ kg which is within the quality parameters. The briquetting of coffee crop wastes is viable and sustainable energetically. |

A cultura do café, importante commodity brasileira, produz resíduos culturais em quantidades diferentes dependendo dos tratos culturais. O Sistema Safra Zero de condução da lavoura é baseado em podas dos ramos plagiotrópicos em anos alternados, possibilitando a concentração da produção e evitando a bianualidade de produção cafeeiro. O presente trabalho teve por objetivo verificar a viabilidade de produção de briquetes a partir do emprego dos restos culturais obtidos no sistema safra zero. Os tratamentos consistiram da briquetagem de: 1) casca de café, 2) mistura de galhos e folhas; 3) 25% de casca de café + 75% de galhos e folhas; 4) 75% casca de café + 25% de galhos e folhas; 5) 50% casca de café + 50% de galhos e folhas; 6) 40% casca de café + 60% de galhos e folhas. Todas as misturas foram realizadas na base de v/v, sendo moídas gerando partículas de 5 a 10 mm, que ao atingirem 12% de umidade, foram processados na forma de briquetes. O teor de carbono dos briquetes produzidos variou de 41,85 a 43,84% e o de enxofre ficou abaixo de 0,1%. O poder calorífico dos briquetes produzidos variou de 3.359,4 a 4.028,3 kcal kg-1 e as cinzas ficaram abaixo de 6%. O uso de casca de café ou galhos e folhas de forma isolada, bem como a mistura de casca de café com 50% ou mais de galhos folhas permitem a produção de briquetes com pode calorífico superior (PCS) em torno dos 4.000 Kcal kg-1, que se encontra dentro dos parâmetros de qualidade. A briquetagem de resíduos da lavoura cafeeira é viável e sustentável energeticamente.UEL2014-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/mswordhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1360710.5433/1679-0359.2014v35n3p1143Semina: Ciências Agrárias; Vol. 35 No. 3 (2014); 1143-1152Semina: Ciências Agrárias; v. 35 n. 3 (2014); 1143-11521679-03591676-546Xreponame:Semina.
