Adsorption of VOC on modified activated carbon fiber

Effect on mass transference phenomena by textural change inside monolithic carbon aerogels

“…of symptoms such as headache, nausea, flu symptoms, pharyngitis, emphysema, lung cancer and even death [1]. Also play a key role in the tropospheric ozone formation (low level of the atmosphere) and other atmospheric oxidants, which produce photochemical smog, a large cities problem [2].…”

“…Therefore, the structural characteristics of the surface in porous materials are the most important factor in the adsorption processes. The importance of the development of micropores in adsorbents for the adsorption of VOCs at low concentrations [1,6,8,9], therefore, the knowledge of morphological characteristics in the micropores allows a better understanding of adsorptive processes on materials.…”

Simultaneous removal of sulfur dioxide and polycyclic aromatic hydrocarbons from incineration flue gas using activated carbon fibers

“…Among these adsorbents, ACFs offer many advantages, including higher adsorption and desorption rates, much higher surface areas, a uniform micropore structure, and a lower pressure drop (Fuertes et al, 2003;Huang et al, 2003;Lillo-Ródenas et al, 2005;Muñiz et al, 2000;Park and Kim, 2001;Yang et al, 2011). The use of ACFs for removing organic compounds from waste gas streams has been extensively studied, indicating that the removal efficiencies of organic compounds are affected by the specific surface area, pore size distribution, pore volume, and surface functional groups of the ACFs and by vapor pressure, molecular size, and molecular weight of organic compounds (Das et al, 2004;Gaur et al, 2006;Lin et al, 2013;Liu, 2006;Liu et al, 2012;Mangun et al, 2001;Yi et al, 2009).…”

“…However, most species of the organic compounds explored in previous studies are volatile organic compounds (VOCs), such as benzene, toluene, and xylene (Das et al, 2004;Gaur et al, 2006;Huang et al, 2003;Lin et al, 2013;Liu et al, 2012;Yi et al, 2009). The 16 species of polycyclic aromatic hydrocarbons (PAHs) listed by the U.S. Environmental Protection Agency (EPA) as priority pollutants are rarely discussed in research of ACFs (Liu, 2006).…”

Photocatalytic Decomposition of Toluene Vapor by Bare and TiO2-coated Carbon Fibers

“…4 In contrast to TiO2/carbon heterostructures, less attention has been paid to the photocatalytic activity of pure carbon structures, even though carbon nanostructures are regarded as efficient adsorbents of organic pollutants. 8,9 Only very recently, photochemical reactivity of graphene was addressed. 10 In the present work, the photocatalytic decomposition rates of toluene by bare and TiO2-coated carbon fibers were studied.…”
