                         presents the steps preparation of the Caucasian hair, for later 
                         carbonization and its transformation as carbonaceous material, 
                         aiming the production of a carbonaceous material activated from a 
                         raw material coming from residues. Some of the steps are the 
                         conversion of hair into felt and the subsequent oxidation which 
                         aims to eliminate the cortex and promote crosslinking between the 
                         protein chains. This process allows the hair to be transformed 
                         into a thermoset, as well as to promote evaporation of the hair 
                         cortex, leaving the hollow filament. As a sequential step, 
                         carbonization and activation of the obtained material was carried 
                         out. Such conditions indicate that Caucasian hair can become an 
                         activated carbon fiber of high surface area and high adsorption 
                         capacity, desirable characteristics for a future application as 
                         molecular sieve.",
