                         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.",
