		<abstract>Este trabalho apresenta as etapas de preparação do cabelo caucasiano para posterior carbonização e sua transformação como material carbonoso, tendo em vista a produção de material carbonoso ativado a partir de matéria-prima proveniente de resíduos. Algumas das etapas consistem na conversão do cabelo em feltro e a posterior oxidação, com objetivo de eliminar o córtex e promover ligações cruzadas entre as cadeias de proteínas; esse processo permite transformar o cabelo em material termofixo, além de promover a evaporação do córtex capilar, deixando o filamento oco. Como etapa sequente, temos a carbonização e a ativação do material obtido. Tais condições indicam que o cabelo caucasiano pode tornar-se uma fibra de carbono ativada de alta área de superfície e elevada capacidade de adsorção, características desejáveis para uma futura aplicação como peneira molecular. ABSTRACT: This work 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.</abstract>
