Thermo-acoustic catalytic effect on oxidizing woody torrefaction

Silveira, Edgar Amaral; Galvão, Luiz Gustavo Oliveira; Macedo, Lucélia Alves de; Sá, Isabella A.; Chaves, Bruno Sant'Anna

The torrefaction (mild pyrolysis) process modifies biomass chemical and physical properties and is applied as a thermochemical route to upgrade solid fuel. In this work, the catalytic effect of thermo-acoustic on oxidizing woody torrefaction is assessed. The combined effect of two acoustic frequencies (1411, 2696 Hz) and three temperatures (230, 250, and 290 °C) was evaluated through weight loss and its deviati...

Adding value to agro-industrial waste for energy purposes

Dionizio, Aline Faleiro; Vale, Ailton Teixeira do; Moreira, Alessandro Cezar Oliveira; Galvão, Luiz Gustavo Oliveira; Chaves, Bruno Sant'Anna

Este estudo teve por objetivo avaliar o potencial energético da matéria-prima residual produzida na colheita ou processamento de culturas agrícolas e florestais, in natura e carbonizada. O experimento resultou em um delineamento inteiramente casualizado, sendo cinco tratamentos e três repetições. As propriedades avaliadas foram: granulometria, densidade do granel, análise elementar, análise imediata, poder calo...
