“…Some of the textural and FTIR data have been already reported (12), although they are included in this paper to help the discussion. The textural characteristics in Table 1 show that the samples of GAe series have larger values of surface areas and micropore volumes than samples of C series.…”

“…The literature provides much insight into carbon surface chemistry and its role in adsorption [3,[13][14][15][16] but this role depends greatly on the adsorbate and very few of these studies have examined surfactants [3,4]. A number of studies have examined carbon surface treatment with ozone [7,13,[17][18][19][20][21][22][23][24][25][26], but only our recent work has focused on its effect on surfactant adsorptivity [7].…”

The overall objective of the present project is to identify and assess strategies and solutions for the management of industry problems related to carbon in ash. Specific research issues to be addressed include:• the effect of parent fuel selection on ash properties and adsorptivity, including a first ever examination of the air entrainment behavior of ashes from alternative (non-coal) fuels.• the effect of various low-NOx firing modes on ash properties and adsorptivity• the kinetics and mechanism of ash ozonation. This data will provide scientific and engineering support of the ongoing process development activities.During this fourth project period we completed the characterization of ozone-treated carbon surfaces and wrote a comprehensive report on the mechanism through which ozone suppresses the adsorption of concrete surfactants.4

Viscose-based activated carbon fibers (VACFs) were treated by a direct-current (DC) discharge plasma at different conditions. The surface functional groups of VACFs were modified to improve the adsorption and catalysis capacity for SO 2 and NO x . The surface properties of the untreated and treated VACFs which were modified in different feed gases (air, O 2 , N 2 and NH 3 ) were performed by scanning electron microscopy, BET, X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared attenuated total reflection spectroscopy (FTIR-ATR). The results show that after being treated with plasma, more particles appeared on the external surface of the VACFs and the surface became rougher, the average pore size decreased but the pore volume and the surface area decreased first and then increased. XPS revealed that DC discharge plasma can remarkably change the distribution of functional groups on the surface of VACFs. FTIR-ATR also indicated that more nitrogen atoms were introduced to the VACFs surface when the feed gas contained nitrogen atoms and N and O atoms were introduced to the surface of VACFs at the same time when the feed gas was air, but it did not happen in the feed gas of N 2 , or O 2 , or NH 3 . Discharge voltage and treatment time were important factors and for our experiment in the feed gas of nitrogen, the optimum modification conditions were 8 kV and 5 min, respectively. 
