Caracterização físico-química de fibra e polpas de Bambusa vulgaris Schrad para...
Guimarães Júnior, Mário; Novack, Kátia Monteiro; Botaro, Vagner Roberto; Protásio, Thiago de Paula; Couto, Allan MottaAtualmente é crescente o interesse pelos compósitos poliméricos reforçados com fibras naturais vegetais em substituição às fibras manufaturadas. Isto se deve ao fato das fibras vegetais serem menos abrasivas, biodegradáveis, apresentar baixa densidade e excelentes propriedades mecânicas e térmicas. Várias fibras vegetais vêm sendo utilizadas nos mais variados tipos de compósitos, dentre as quais as de bambu se ...
Steel and energetic potential of charcoal of Eucalyptus spp. clones at 42 month...
Protásio, Thiago de Paula; Couto, Allan Motta; Reis, Aliny Aparecida dos; Trugilho, Paulo Fernando; Godinho, Tayana PedrozoThe aim of this study was to evaluate the steel and energetic potential of charcoal of clones of Eucalyptus grandis and Eucalyptus urophylla at 42 months of age. Wood from seven clones were used. The carbonizations were performed in an electric furnace (muffle) with final temperature of 450 °C. The carbonization yields, immediate and elemental chemical composition, higher and low heating value, apparent relativ...
Chemical and energetic characterization for utilization of thinning and slab wo...
Bufalino, Lina; Protásio, Thiago de Paula; Couto, Allan Motta; Nassur, Otávio Augusto Carvalho; de Sá, Vânia Aparecida; Trugilho, Paulo FernandoThis work aimed to quantify and compare chemical and energetic properties of Australian red cedar Toona ciliata MJ Roem var. australis (FV Muell.) C. DC wood from thinning and primary sawing for reconstituted panel and energy production; and also to verify the efficiency of extractive removal by water treatments, in order to improve wood quality for particleboard production. Lignin, holocellulose, extractives, ...
Relation between higher heating value and elemental and mineral biomass plant c...
Protásio, Thiago de Paula; Bufalino, Lina; Tonoli, Gustavo Henrique Denzin; Couto, Allan Motta; Trugilho, Paulo Fernando; Guimarães Júnior, MárioThe aims of this work were to evaluate the correlation, to adjust and select simple and multiple linear statistical models between elemental components (carbon, hydrogen and oxygen) and ash content with higher heating value for plant biomass; to use the principle components analysis for the creation of an energetic development index and to adjust a linear model between energetic development index and higher hea...
Evaluation of Eucalyptus clones in different places seeking to the production o...
Neves, Thiago Andrade; Protásio, Thiago de Paula; Couto, Allan Motta; Trugilho, Paulo Fernando; Silva, Vinícius Oliveira; Vieira, Carlos Magno MeloThis research aim to evaluate the wood and charcoal quality of three Eucalyptus clones planted at different places and to verify the existent functional relations between the basic density and the depth of penetration of the Pilodyn pin. Three Eucalyptus clones were evaluated and four trees were sample for each clone and place. It was determined the depth of penetration of a Pilodyn pin at 1.30 m of height of t...
