Mesoporous Activated Carbon Fibers from Lignocelullosic Materials: Adsorption Studies
High surface area and highly mesoporous activated carbon fibers (ACF) were obtained by physical activation of natural precursors (vetiver roots and bagasse) with steam and chemical activation using phosphoric acid. The textural characteristics of the activated were determined by nitrogen adsorption study and mercury porosimetry and showed that interesting porosity were obtained (SBET up to 1600...
متن کاملStructural characterization of heat-treated activated carbon fibers
Raman scattering, x-ray diffraction, and BET measurements are used to study the effect of heat treatment on the microstructure of activated carbon fibers (ACFs) and to correlate the structural changes with the metal-insulator transition observed in the electronic transport properties of heat-treated ACFs. A sequence of events is identified, starting with desorption, followed by micropore collap...
متن کاملElectrochemical Capacitive Desalination Behavior of Activated Carbon Fibers
Introduction Capacitive deionization (CDI), which is ion electrosorption onto the surface of porous materials to remove ions from aqueous solutions, may serve as an energy-efficient alternative for the desalination of brackish water comparing with conventional desalination methods such as membrane separation and thermal distillation [1]. The CDI process operates at low direct voltages. Ions ads...
متن کاملFABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS
Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...
متن کاملEffect of Pore Size on Adsorption of Hydrocarbons in Phenolic-based Activated Carbon Fibers
The combined effect of pore size and pore volume on the equilibrium adsorption capacity and the adsorption kinetics for a series of normal alkanes is determined. The selected adsorbents, activated carbon fibers (ACFs) and air activated phenolic fibers (AAPFs), possess a range of micropore sizes and have been thoroughly characterized in past work. For the normal alkane series, the lower surface ...
