abstract = "Carbon fibers and activated carbon fibers are materials of high
industrial interest. When presented as a felt, its use becomes
easier and more practical. This work aims to study the conditions
for obtaining and characterizing an activated carbon felt, using
sheep wool as a precursor. The wool felt was oxidized, carbonized
in nitrogen atmosphere and activated in water vapor. The working
temperatures were selected through thermogravimetric analysis. The
products and intermediates were characterized through
thermogravimetric analysis, infrared spectroscopy, scanning
electron microscopy, Raman spectroscopy and nitrogen
adsorption-desorption. The products were assessed as potential
sorbents for methane-carbon dioxide separation by adsorption
kinetics measurements at different pressures. Results revealed a
high influence of the carbonization temperature on the
physicochemical and textural properties of the products. The
adsorption kinetics and capacities of the gases showed that
selectivities in separation were related to both felt
carbonization temperature and gas pressure. This work revealed
that activated carbon wool felts are a good alternative to
synthetic fibers felt and they can be used for methane/carbon
dioxide separation.",
