Abstract:
In this work the combustion behavior of lignin-rich solid residue from reed (Arundo donax) was investigated in atmospheres of oxygen, i.e. 21 kPa and 101 kPa. The residue derived from processing reed that was pretreated by continuous steam explosion, then hydrolyzed by enzymes, recovered by filtration and dried. The lignin residue was analyzed to determine volatile and fix carbon, ash, C, O, H, N, S, Cl, LHV and HHV. The kinetic parameters for combustion of the char obtained from it by pyrolysis at 900°C were determined by TGA in the range 360 °C-380 °C and pO2 21 kPa-101 kPa. The activation energy resulted 120 kJ/mol in agreement with literature data on chars derived from biomass. The reaction order resulted 0.5 and is consistent with a chemical controlled regime, with dissociative adsorption of the O2 molecule.
