             abstract = "Activated carbon fibers (ACFs) are known as excellent adsorbent 
                         materials due to their fast adsorption rate and easy handling 
                         characteristic. The ACFs can be manufactured from the 
                         poliacrilonitrile fiber, based on a usual carbon fibers (CFs) 
                         production process accomplished by an additional activation 
                         process. On the other hand, activated carbon fiber may be 
                         manufactured by poliacrilonitrile from textile use. The aim of the 
                         present work is to describe the production, characterization 
                         results, and application studies 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 
                         fases, SEM, DRX, RAMAN surface chemistry. The results confirmed 
                         the production of essentially microporous (pore < 3.2 nm, centered 
                         on 1.2 nm), 1.300 m2/g activated carbon fiber felt. After that was 
                         performed electrochemical characterization for studies application 
                         as a supercapacitor electrode.",
