             abstract = "Activated carbon fibers (ACF) are known as excellent adsorbent 
                         materials due to their fast adsorption rate and easy handling 
                         characteristic. The ACF can be manufactured from the 
                         polyacrylonitrile fiber, based on an usual carbon fibers (CF) 
                         production process accomplished by an additional activation 
                         process. The aim of the present work is to describe the 
                         production, chemical/morphological characterization and 
                         application potentiality of activated carbon fiber felt (ACFF) 
                         produced from textile PAN fiber, using a set of homemade 
                         equipment. The 5.0 dtex PAN fiber tow with 200 thousand filaments 
                         was oxidized and used as raw material for felt production. The 
                         oxidized PAN fiber felt (OPFF) was displaced in a special sample 
                         holder, carbonized (900 °C) and then activated in CO2 atmosphere 
                         at 1000 °C in an electric tubular furnace. All steps of the 
                         process were performed as fast as possible, and characterization 
                         was done by 77 K N2 isotherms, adsorption isotherms in liquid 
                         phase, scanning electronic microscope, X-ray diffraction and 
                         surface chemistry by Bhoem methodology. The results confirmed the 
                         production of essentially microporous (pore < 3.2 nm, centered on 
                         1.2 nm) and 1,300 m2 g-1 surface area. The ACFF produced have 
                         demonstrated a strong potential application as electrode 
                         supercapacitor. RESUMO: Fibras de carbono ativado (FCA) s{\~a}o 
                         conhecidas por ser um excelente material adsorvente devido sua 
                         elevada cin{\'e}tica de adsor{\c{c}}{\~a}o e facilidade de 
                         manuseio. As FCA podem ser produzidas a partir da fibra de 
                         poliacriolonitrila e mesmo processo utilizado na 
                         fabrica{\c{c}}{\~a}o de fibras de carbono, acoplando-se uma 
                         etapa de ativa{\c{c}}{\~a}o ao final do processo. Neste trabalho

                         (FFCA), produzidos a partir de fibra PAN t{\^e}xtil nacional em 
                         um equipamento experimental. Fibras PAN de 5.0 dtex em cabo de 200 
                         mil filamentos foram oxidadas termicamente e utilizadas como 
                         mat{\'e}ria prima para a produ{\c{c}}{\~a}o de feltro. O feltro 
                         de fibra PAN oxidada (FFPO) foi colocada em um porta amostra, 
                         especialmente desenhado, e inserido em um forno tubular 
                         el{\'e}trico, carbonizado (900 °C) e em seguida ativado em 
                         atmosfera de CO2 a 1000 °C. Todas as etapas foram feitas na maior 
                         taxa poss{\'{\i}}vel e as caracteriza{\c{c}}{\~o}es foram 
                         feitas por isotermas de N2 a 77 K, a qu{\'{\i}}mica de

                         microporoso (poros < 3,2nm, concentrados em 1,2 nm) e 1300 m2 de 
                         {\'a}rea espec{\'{\i}}fica. O material produzido apresentou
