Resumen:
The coupling of concentrated solar technologies and thermochemical
biomass conversion is a promising alternative because there is an
improvement on the process efficiency and a reduction of the
environmental impact related to the use of fossil fuels for heat
process. Therefore, the use of solar pyrolysis of agro-industrial wastes
into fuels results attractive due to the biomass versatility to be
transformed in a variety of products. In the present work, leaves of
agave Angustifolia were used as raw material to performed the solar
pyrolysis in the IER-UNAM solar furnace (Mexico) to produce amorphous
carbon. The experiments were performed in a borosilicate reactor at
different temperatures (450-1550 degrees C), with an average heating
rate of 30 degrees C/min and 60 min of residence time. The main results
show a variety of yields in the char produced from 28-14%, and
conversion up to 85%. In addition, according to the temperature range,
the amorphous chars produced may be suitable for energy storage in
symmetric supercapacitors as carbon electrodes.
