Jerusalem artichoke pyrolysis: Energetic evaluation

摘要: Abstract The pyrolysis process of Jerusalem artichoke (Heliantuhus tuberosus L.) waste was carried out. objective this work to characterize the solid, liquid and gaseous phases, studying influence operating variables determining optimal conditions. Thus, temperature (400–800 °C), particle size (0.63–2.00 mm), N2 flow rate (75–300 mL min−1) initial sample mass (2.5–10 g) were investigated. In these series, yields three their higher heating value proximate analysis solid phase determined. Under conditions study, an increase in reaction leads a decrease gas yield. However, variation do not exert defined yield phases. On other hand, increasing causes yields. According energetic characterization phases generated, different uses proposed. Finally, as previous step design industrial equipments, kinetic study process, based on generation principal gases, accomplished. With purpose, it considered that gases are formed through parallel independent first-order reactions, with activation energies. From model, constants for formation each corresponding energies
