Resumen:
Physico-chemical characteristics of raw stems of giant reed (Arundo donax L.) and
of the char obtained by pyrolysis at 500 °C and 800 °C under flowing N2, as well as
char yield, were determined to examine features evolution and potential applications.
The chars derived at both temperatures were found potentially suitable as solid biofuels.
Char features and yield at the lower temperature were compared to those from
pyrolysis of the stems pre-treated with a phosphoric acid solution under otherwise
identical conditions. The acid treatment induced an enhanced char yield and a highly
developed porous structure with surface properties similar to those characterizing
activated carbons. Thermogravimetric analysis also showed substantial changes in
pyrolytic behavior of the treated stems. They seem to be due to the catalytic action of
the acid promoting degradation at lower temperatures compared to pyrolysis of the
untreated stems.
