| Abstract | Study of eucalyptus forest residues and sugar cane bagasse torrefied biomass for energy purposes The objective of this study was to analyze the effect of the heat treatment application, with different intensities in forest residues of Eucalyptus grandis and sugar cane bagasse in order to improve its features to use as fuel. The biomasses were subjected to laboratory heat treatments comprising temperatures of 250 and 280°C during 0,5 and 2,0 hours. After that, the original and treated biomasses were subjected to laboratory tests including: chemical composition (lignin and extractives), immediate composition by determining the levels of volatiles, fixed carbon and ash, calorific value, thermogravimetry, grain size and friability. The results show that there is an influence of temperature on the yields of biomass analyzed. In general, the treatments with higher temperatures present lower yield. There was an increase in fixed carbon content, reducing the volatile components and ash content increased for both biomasses. The two materials showed very similar behavior on chemical composition. The increase of the intensity of heat treatment caused an increase in lignin content of the materials. It was possible to observe that the heat treatment presented an influence on particle size reduction and increases friability in both the forest residues of Eucalyptus grandis and sugar cane bagasse. |
