چکیده انگلیسی
Medium Density Fiberboard (MDF) wastes were undergoes via a thermal treatment through of a pyrolysis process. Pyrolysis was carried out in a pilot scale reactor with screw conveyor at two reaction temperatures (450 and 600 °C) and, for each one, three solid residence times (9, 15 and 34 min) were evaluated. Products (char/bio-oil/fuel gas) of the pyrolysis process were characterized and quantified. Results revealed that the products yields were influenced by pyrolysis temperature, as well as by solid residence time. Char yield ranged between 17.3 and 39.7 (wt.%), the bio-oil yield ranged between 23.9 and 40.0 (wt.%), while the fuel gas yield ranged between 34.6 and 50.7 (wt.%). The samples surface area at 450 and 600 °C in 15-min residence time were surprisingly high, 415 and 593 m2 gâ1, respectively, which are compatible with the superficial area of commercial activated carbons. Energetic efficiency of process was estimated from energetic content present in the reaction products and the energetic content of MDF wastes, and the following results were obtained: 41.4% (fuel gas), 35.5% (char) and 29.2% (bio-oil). The contribution of this work is the development of a detailed study of the MDF pyrolysis in a pilot reactor with screw conveyor that supports the biorefineries concept.
