Biomass degradation kinetic mechanisms involving both condensed-phase pyrolysis and secondary gas-phase reactivity of volatiles. Solid-phase version 2502, gas-phase version 2003. A simple reaction has been considered for char oxidation, while a more detailed surface char-oxidation is considered with a separate heterogeneous mechanism
The initial composition of the biomass is obtained from biochemical analysis or the updated characterization procedure (Debiagi et al, 2015) based on the biomass elemental analysis. Two versions are available:
- The mechanism with only solid reactions (60 species, 32 reactions)
- The complete mechanism with gas-phase reactions as well (650 species, 20000 reactions) The lists of species involved in the solid-mechanism is reported in the list_of_species_solidmechanism file
