Qualidade de black pellets de finos de carvão vegetal produzidos com diferentes...
Carvalho, Felipe Barbosa; Martins, Caio Cesar Nemer; Peres, Letícia Costa; Surdi, Paula Gabriella; Lima, Laura Vitória LopesCharcoal fines are co-products of the wood carbonization process, unwanted because they reduce the gravimetric yield of the main product, charcoal. It can be produced due to the carbonization process, during the storage and transport of charcoal. Pelletizing charcoal fines increases the energy density of this material, producing a homogeneous fuel with lower moisture content, enabling burning in equipment with ...
Sustainable Solid Biofuel Production: Transforming Sewage Sludge and Pinus sp. ...
Pereira, Alex Borges; Zanuncio, Antonio José Vinha; Carvalho, Amélia Guimarães; Carneiro, Angélica de Cassia Oliveira; Castro, Vinícius Resende deThe lack of adequate sanitation in Brazil overloads the health system and causes deaths. The utilization of sewage sludge hinders advancements in water treatment. This study aimed to assess the feasibility of producing briquettes by blending sewage sludge with Pinus sp. sawdust. The sewage sludge was sourced from a water treatment facility, while the Pinus sp. sawdust was obtained from a sawmill. Elemental anal...
Tannin extracts as a preservative for pine thermomechanically densified wood
Niela de Lima, Nídia; Castro, Vinícius Resende de; Lopes, Nayara Franzini; Nunes, Ítalo Lima; Andrade, Frances Alves; Zanuncio, Antonio José VinhaThermo-mechanical densification modifies wood to produce a more dense and resistant lignocellulosic material and may degrade extractives that contribute to the increased susceptibility of wood to attack by xylophagous organisms. This study evaluated the efficiency of tannin extracts of Acacia mearnsii in the treatment of thermo-mechanical densified pine wood in relation to physical, mechanical, and biological r...

Influência de idade e da posição radial nas dimensões das fibras e dos vasos da...
Silva, José de Castro; Tomazello Filho, Mário; Oliveira, José Tarcísio da Silva; Castro, Vinícius Resende deObjetivou-se neste trabalho avaliar a variação das dimensões das fibras e dos vasos da madeira de Eucalyptus grandis com quatro diferentes idades (10, 14, 20 e 25 anos), proveniente de talhões comerciais. A amostragem do material na árvore foi feita através da coleta de três discos, retirados da base e das extremidades das duas primeiras toras, ambas com o comprimento comercial de 3 m. De cada disco, retiraram-...
