Titre anglais : Influence of temperature on products yield of Eucalyptus microcorys carbonization

Quartile : Q4, Sujet : FORESTRY

Abstract : During charcoal production different products are formed. These products are influenced primarily by the temperature of carbonization. Given that charcoal is the main input in the production of pig iron in Brazil, this study evaluated the influence of final temperature of carbonization of the products generated and also the influence of the radial and longitudinal sampling on the yield of each product. Samples were taken from internal and external position along the radius and also from three different heights from four Eucalyptus microcorys trees. The samples were carbonized in an electric furnace with an experimental water-cooled condenser and a collecting bottle of condensable volatile materials. The final temperatures of carbonization were 500, 600, 700, 800 and 900°C. The gravimetric yield, tar and non-condensable gases were calculated. The results showed no difference in the gravimetric yield in the longitudinal and radial positions studied, while the tar yield and non-condensable gases showed temperature variations of 700°C and 800°C and the variation of the gravimetric yield temperatures between 500°C to 900°C was 15%, the change of yield of tar from the radial direction of sampling was on average 8%, the variation of the yield of non-condensable gases in a radial sampling was on average 16%.
