Estudo da carbonização de madeira de Acácia mangium Wild

Abstract

Acacia mangium is a legume species, naturally occurring trees in northeastern Australia, Indonesia (Moluccas and Java) and the province of Papua New Guinea. It features excellent performance, superior to several species of eucalyptus, reaches heights of up to thirty meters and can reach production of 46 m3 / ha / year. This work aimed to evaluate the charcoal produced from carbonization of the wood of Acacia mangium, analyzing the gravimetric yield of carbon, pyroligneous liquor and tar, and determine the method of chemical analysis the content of ash, volatile matter and fixed carbon of coal produced. And to verify the variation of wood basic density of the species Acacia mangium in the longitudinal direction of the trunk, in the sections 0% 25% 50% 75% 100% up to commercial height. From the results we observed that the basic density of trees decreases with height. The coal gravimetric yield was 32.71%, 30.95% of pyrolignous, tar 5.37%. The ash content was 1.11% of volatile material was 17.80% and fixed carbon was 81.09%. The charcoal produced had a good quality for the steel industry.
