Propriedade do carvão da madeira e da casca de Eucalyptus sp. plantado na região do Recôncavo da Bahia

Abstract

In this work, three Eucalyptus sp trees were used. which were sampled at three points: base, middle and top. The diameters with bark and without bark were measured at five different heights of the tree to determine the volume of bark. Three wood and three bark carbonizations were carried out on each tree, determining the gravimetric carbonization yield. The determined shell volume was 9.68%. Both gravimetric yield and immediate chemical analysis showed significant statistical differences between charcoal produced from wood and bark. Thus, it can be stated that in general, the bark presents charcoal properties lower than those observed for wood charcoal. Therefore, when higher densities, higher fixed carbon contents and smaller amounts of ash are required, the bark must be removed.
