Résumé
Cortaderia selloana (CS), is an invasive and exotic species that is generating significant invasive
problems in the Iberian Peninsula ecosystems. The objective of this research was to study this
plant potential thorough a pyrolytic process helping to reduce its expansion. Stems and leaves
were subjected to conventional and flash pyrolysis. These processes were carried out in an
original design oven using a 25°C/min heating ramp at a 750°C temperature and during 60 min
at the pyrolysis temperature for conventional pyrolysis and with 750°C and 850°C pyrolysis
temperatures for flash. Gas-fraction obtained by flash pyrolysis had higher HHV data when
compared with conventional ones (~17 MJ/kg vs ~ 5 MJ/kg) due to their less CO2 and higher
CO, CH4 and H2. The greater bio-oil yield was obtained for CSS-P (33.58%). The composition of
conventional pyrolysis bio-oils had an overbearing of nonaromatic and monoaromatic
hydrocarbons nature whereas bio-oils from flash pyrolysis were composed mainly of polycyclic
aromatic hydrocarbons. Bio-char fraction was higher in CSL than CSS with HHV similar to lignite
and bituminous coals (22.74 to 29.12 MJ/kg). After done the quantification and characterization
of the fractions, it was concluded that a possible energetic valorization of Cortaderia selloana
biomass was possible.
