Abstract: Adsorption-desorption isotherms of aromatic (mesitylene and toluene) and aliphatic (methylcyclohexane, neopentane and n-pentane) hydrocarbons were measured on ordered mesoporous materials, including MCM-41, MCM-48, SBA-15, SBA-16 and MCF silicas, a periodic mesoporous organosilica and a CMK-3 carbon, in order to evaluate the effect of the adsorbent characteristics on the organic compounds adsorption behaviour. A clear separation between aliphatic and aromatic hydrocarbons is observed at low p/p o for the mater… Show more

“…7 Mesoporous silicas also have great potential for the removal of VOCs because of their large BET surface area, controllable and uniform pore size, open pore structure, high porosity, good mechanical stability, and in particular, reliable desorption performance. In previous studies, MCM-41, MCM-48, SBA-15 and HMS type mesoporous silicas have been used as adsorbents for the VOC removal, 2,[9][10][11][12][13][14][15][16] all with pure silica composition in the skeleton. In previous studies, MCM-41, MCM-48, SBA-15 and HMS type mesoporous silicas have been used as adsorbents for the VOC removal, 2,[9][10][11][12][13][14][15][16] all with pure silica composition in the skeleton.…”

“…They found saturation capacities between 10.8 mmol g −1 (779 mg g −1 , n ‐pentane) and 7.2 mmol g −1 (822 mg g −1 , n ‐octane) for pure MIL‐101, and 13.4 mmol g −1 (967 mg g −1 , n ‐pentane) and 9.3 mmol g −1 (1062 mg g −1 , n ‐octane) for the composite material. These values are compared with capacities of the common coal and silica materials, e.g., CMK‐3 carbon with a n ‐pentane capacity of 8.6 mmol g −1 (620 mg g −1 ), BAX950 with a n ‐octane capacity of 5.2 mmol g −1 (594 g g −1 ), or MCM‐48 with a n ‐pentane capacity of 8.2 mmol g −1 (591 mg g −1 ) …”

“…For the methylated and trifluoromethylated surfaces, the filled and empty symbols are for η=0.7 and 1, respectively (η, substitution ratio of SiOH by SiCH 3 or SiCF 3 ).+and × are EP experimental data for the two silica samples. Purple × signs are for hydroxylated MCM‐41/SBA‐15 while purple+signs are for oxide surfaces …”
