First, flash carbonization was carried out in a muffle furnace, in which wood samples were heated to a maximum temperature of 500°C, and the product yields were determined. The chemical analysis of the wood of each species for the determination of extractive, lignin and ash contents was performed. TGA was performed using sawdust samples heated at 10°C.min−1 up to 625°C under a nitrogen atmosphere at a flow rate of 50 mL.min−1. The thermal decomposition profile was used to evaluate which wood species was more thermally stable. Mimosa tenuiflora and Poincianella pyramidalis woods were the most suitable as biomass energy sources for charcoal production because of their thermal stability and satisfactory carbonization yields. The thermal stability of the 10 wood samples was confirmed by the analysis of the carbonization yields. 2019 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74460212006 https://www.redalyc.org/journal/744/74460212006/ https://www.redalyc.org/journal/744/74460212006/html/ https://www.redalyc.org/journal/744/74460212006/74460212006.epub https://www.redalyc.org/journal/744/74460212006/movil 10.1590/01047760201925012602 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.1 Vol.25 |
