| This research aimed to analyze the quality and yields of the charcoal of a Eucalyptus grandis x Eucalyptus urophylla hybrid clone commercially named GG100 for use in iron industry at different ages, plantation sites and spacing. The wood was carbonized in a laboratorial electric furnace (muffle furnace) at a heating rate of 1.67 ºC min-1 until the final temperature of 450 ºC, remaining stabilized for 30 min. The gravimetric yield in charcoal, pyroligneous extract, non condensable gases and insoluble tar, proximate and elemental chemical composition, relative apparent density and higher heating value of the charcoal were determined. In general, the charcoal evaluated may be considered homogeneous based on chemical and physical aspects and can be used in the... |

| This study aimed to produce and evaluating the briquettes made from residues of plant biomass and test different times and temperatures. The material utilized was composed of wood processing residues (wood shaving and sawdust), coffee bean parchment and coffee tree stem, beam stem and pod, soybean stem and pod, rice husk, corn leaf, stem, straw and cob and sugar cane straw and bagasse. Briquetting was performed at a pressure of 150 Bar. Different times were tested for briquetting sawdust from wood and different temperatures for rice husk and parchment coffee. For evaluation of the briquettes quality, the apparent relative density, compression resistance and combustion index were determined. The results indicated that the briquetting time and temperature... |
