Caracterização anatômica da madeira e do carvão vegetal de Hovenia dulcis Thunberg

Abstract

Currently, Brazil is the largest producer and consumer of charcoal in the world, however, works related to charcoal from Hovenia are scarce, being a kind of alternative to both anatomical and energy studies. The present work aimed to characterize the anatomical wood and charcoal of Hovenia dulcis Thunberg. For this, 2.5x2.5x5.0 DAP tall discs were used for anatomical analysis of the wood and the rest of the disc used for carbonization and density. An anatomical analysis was performed following the description of the IAWA (1989) norms, without tangential sense, analyzed by linear radii millimeter, radius length and width in the micrometer and radius length and width by the number of cells; no transverse direction was analyzed pores per square millimeter and width then the basic and apparent density of the wood was determined. Carbonization was performed in a muffle furnace with approximately 300g of wood. After the carbonization process, the anatomy of the Hovenia dulcis coal was analyzed. Changes in the carbonization process of the wood anatomy for charcoal were observed, such as a greater trend in vessel frequency per mm² and, consequently, a decrease in vessel diameter.
