“…(57) However, Davini suggested that surface area is the key physical parameter determining adsorptive capacity of activated carbon for SO 2 , (19) while Daley et al reported that the pore size and volume are more important than surface area. (20) There are also conflicting arguments on effect of pore size distribution (importance of micropores versus the transport pores) on SO 2 adsorption capacity of carbon. (17,18) Therefore, the role of the morphological heterogeneity of carbon surfaces is not clearly understood and is still an object of intense study.…”

“…(16) However, the role of the morphological heterogeneity of carbon surfaces is not clearly understood and is still a subject of intense study. (17)(18)(19)(20) The objectives of this study are to investigate these issues through fundamental studies of adsorption and desorption of a model adsorbent representative of volatile polar (acetone), nonpolar (propane) organic compounds and vapor phase elemental mercury on a model carbonaceous surface (HOPG, highly oriented pyrolytic graphite), in ultra high vacuum (UHV)…”

“…In this case SO 2 is catalytically oxidised to SO 3 and sulphuric acid is formed. The reported carbon materials applied in this method are: coke, porous active carbon 1-4 , carbon fi bres 5, 6 or carbon nanomaterials. The removal of SO 2 on activated carbons (ACs) and activated carbon fi bres (ACFs) in presence of oxygen at room temperature was described in 1 .…”

The aim of the work is to describe a capability of the active carbon CARBON L-2-4 (AC) and of the nanocarbon (NC) materials containing iron nanoparticles to continuously remove SO 2 from air. The carbon nanomaterials (NC) containing iron nanoparticles were synthesised using a chemical vapor deposition method -through catalytic decomposition of ethylene on nanocrystalline iron. The process of SO 2 removal was carried out on dry and wet with water carbon catalyst (AC or NC) and was studied for inlet SO 2 concentration 0.3 vol.% in the presence of O 2 , N 2 and H 2 O, in the temperature range of 40-80 o C.

Iron incorporated zeolites were prepared from Na-A type zeolite synthesized from melting slag and FeCl 3 solution and applied as adsorbents for NH 3 and H 2 S gases. Iron incorporated zeolite was pelletized, calcined and used for gas adsorption experiment. XRD analyses of the zeolite revealed that Fe 3þ concentration of solution more than 90 mM could destruct the zeolite network structure. It was observed that the gas adsorption capacities of these zeolite pellets depend significantly on iron concentration of solution and calcination temperature. The type of binders affected a little on gas adsorption capacities. From adsorption results, adsorption capacity for NH 3 was proportional to Fe 3þ concentration and it was increased with calcination temperature up to 500 C, but it was decreased over 600 C. Pellets prepared from 56 mM Fe 3þ solution calcined at 500 C showed highest ammonia adsorption capacity (3.7%). This iron incorporated Na-A type zeolites showed much higher adsorption capacities for NH 3 (2:4$3:7%) than commercially available activated carbons (0:16$0:44%) and zeolites (0:23$0:60%). In the case of adsorption capacities for H 2 S, adsorption capacity was proportional to Fe 3þ concentration and inversely proportional to calcination temperature. Pellets prepared from 78 mM Fe 3þ solution calcined at 200 C showed highest hydrogen sulfide adsorption capacity (1.5%). Adsorption capacity (0:2$1:5%) was found to be lower than that of the commercial activated carbons (1:2$2:4%) and higher than that of commercial zeolites 4A (0.15%) and 13X (0.91%). Higher ammonia adsorption in iron incorporated Na-A zeolites could be possibly due to development of number of acid sites on the zeolites surface due to incorporation of Fe 3þ ion.
