Wood and charcoal energy properties of Cenostigma macrophyllum: subsidies to sustainable use PFB - Pesquisa Florestal Brasileira
Araújo, Ana Clara Caxito de; Costa, Luciano Junqueira; Braga, Pedro Paulo de Carvalho; Neto, Rosalvo Maciel Guimarães; Rocha, Maria Fernanda Vieira; Trugilho, Paulo Fernando.
This study aimed to evaluate the quality Cenostigma macrophyllum Tul wood for energetic use and to determine the yields and charcoal properties produced at different carbonization temperatures. Discs with 3 cm of thickness were obtained from stem basal positions, 25%, 50%, 75% and 100% of commercial height. The discs were split in two parts. One was used to determine wood properties and the other was carbonized at final temperatures of 400 ºC, 500 ºC and 600 ºC for bio-reducer evaluation . Basic density (1.2 g cm-3), lignin content (34%), higher calorific value (4,845 cal g-1) and gravimetric yield in charcoal (GYC) at 400 ºC (41.5%) were the highlights. The increase of wood pyrolysis temperature from 400 ºC to 600 ºC resulted in 29.4% increase in fixed...

Physical and energetic properties of wood and charcoal of Hieronyma alchorneoides PFB - Pesquisa Florestal Brasileira
Carvalho, Adriel Furtado; Brand, Martha Andreia; Nones, Daniela Letícia; Marco, Franchesco Thomas; Friederichs, Gustavo; Weise, Solange Maria Krug.
The aim of this study was to determine the physical and energetic properties of wood and charcoal obtained by carbonization of Hieronyma alchorneoides Allemão (licurana). Coal produced in family farming Biguaçu, SC, is to supplement the income. The most important results are: specific gravity of the timber presented 530 Kg m-³ and the gross calorific value greater of 4.315 kcal kg-1. The coal gravimetric yield was 37% and gross calorific value was 6.740 kcal kg-1. The wood of H. alchorneoides presents physical properties suitable for charcoal production. The charcoal showed excellent gravimetric yield.
