Aproveitamento de resíduos madeireiros de Pinus sp. com diferentes granulometrias para a produção de briquetes

Abstract

O presente trabalho teve como objetivo avaliar o efeito da granulometria da biomassa residual da madeira de Pinus sp. na qualidade de briquetes. A biomassa residual utilizada foi obtida do processo industrial de processamento da madeira de Pinus sp., sendo classificada em (i) serragem; material residual do processo industrial apresentando granulometria diversa e (ii) moída; material moído e classificado na peneira de 60 mesh. Da biomassa foram determinados os teores de materiais voláteis, cinzas e carbono fixo, poder calorífico superior, densidade a granel e energética e produzidos briquetes em briquetadeira laboratorial com temperatura de 120ºC, tempo de prensagem de 5 minutos, pressão de 140 kgf.cm‑2 e tempo de resfriamento de 10 minutos. A qualidade dos briquetes foi determinada pelas variáveis energéticas e físico-mecânicas: densidade aparente e energética, durabilidade, resistência à tração por compressão diametral e expansão volumétrica. Os resíduos de biomassa de Pinus sp. provenientes do processamento da madeira são adequados para a confecção de briquetes. Não houve efeito significativo da granulometria da biomassa de Pinus sp. nas características energéticas e físico-mecânicas dos briquetes. A utilização da biomassa residual obtida diretamente do processamento da madeira de Pinus sp. é recomendada para produção de briquetes em detrimento a biomassa mais fina, com 60 mesh, pois a ela estão atrelados menores custos de produção, sem a necessidade de reprocessamento da matéria-prima e adequação granulométrica.
