Removal of SO2 by activated carbon fibers in the presence of O2 and H2O

Adsorbents based on carbon microfibers and carbon nanofibers for the removal of phenol and lead from water

“…Recently, activated carbon fibers (ACFs), carbon nanotubes (CNTs), carbon nanoparticles, and carbon microspheres have been used as adsorbents for the aqueous phase removal of phenol and metallic ions, including Pb 2+ [13][14][15][16][17][18]. In our recent studies, a phenolic resin precursor based on ACF was prepared from non-activated fabrics for the removal of gaseous phase pollutants [19][20][21][22]. More recently, we developed a hierarchal web of carbon microfibers and nanofibers, which were effective in the removal of NO x from air [23], and fluoride and arsenic (V) ions from water [24,25].…”

Application of Fibrous Activated Carbon Filter in Continuous-Flow Unit for Removal of Volatile Organic Compounds under Simulated Indoor Conditions

“…The adsorbent particle mass transfer and pore diffusional resistances usually control the adsorption process of various chemical species (Tsibranska et al, 2000). Several studies (Davini, 2003;Das et al, 2004;Gaur et al, 2006) have reported that the FAC particle mass transfer resistance would be negligible for the adsorption rates of gas-phase compounds, such as VOC or SO 2 , on FAC. Therefore, the descending adsorption capacity observed for BT was ascribed to low pore diffusion of BT molecules under high SFR conditions (Gaur et al, 2006).…”

Ultrafine porous carbon fibers for SO2 adsorption via electrospinning of polyacrylonitrile solution

“…1. The details of the test are described elsewhere [29]. Then a gas mixture containing SO 2 was introduced into the reactor packed with the required amount of sample after the reactor had been heated to the desired temperature.…”
