Resumen:
Carbon materials can be produced by different methods, one of them is
solar pyrolysis, which is attaining renewed interest due to simplicity
to transform biomass with environmental advantages. However, pyrolysis
operation parameters are decisive factors that determine the
morphological and chemical properties of carbon. This work aims to study
the influence of temperature and heating rate of solar pyrolysis in the
properties of carbon. Pyrolysis experiments were carried out in the 25
kW IER-UNAM solar furnace. Agave biomass was processed in a glass
spherical solar reactor. Temperatures between 500 and 900 degrees C were
utilized, as well as heating ramps between 4 and 30 degrees C/min.
Samples were analyzed with several techniques. The results of the
experiments indicate that solar pyrolysis temperature and heating rate
scarcely impact the carbon composition, however the structure, surface
area and electrochemical response are highly affected by both. The
control of the operation conditions allows to produce carbon materials
that exhibit promising properties to be used as catalyst supports for
polymer electrolyte membrane fuel cells and electrolyzer cells
applications. Therefore the use of concentrated solar energy represents
an attractive method to obtain these valuable materials.
