Slow Pyrolysis of Quercus cerris Cork: Characterization of Biochars and Pyrolysis Volatiles

Waste cork granules of Quercus cerris bark were subjected to isothermal and non-isothermal slow pyrolysis. The heat the reaction, as well yields properties biochar, bio-oil, pyrolysis gas investigated by thermogravimetric analysis, FT-IR, CHN elemental higher heating value (HHV) determinations, scanning electron microscopy (SEM), chromatography (GC). was carried out in a semi-batch reactor using an or dynamic approach. results demonstrated that is slightly exothermic reaction produces biochars. analysis indicated non-isothermally produced chars have similar fuel compared isothermally chars. FT-IR showed suberin undergoes degree degradation aromatization begins char structure. Bio-oils are also they consist C5–C12 hydrocarbons with C8 carbon compounds making up main fraction. Lighter components, mainly C1–C2 collected phase. overall indicate possible reduced-cost route for production cork-based biochars
