Adsorption of thiophene and toluene on NaY zeolites exchanged with Ag(I), Ni(II) and Zn(II)

Synthesis of cyclopentadiene trimer (tricyclopentadiene) over zeolites and Al-MCM-41: The effects of pore size and acidity

“…2(a). The isotherms of the ZSM-5 and HY zeolites were type I, which is typical for microporous materials [37]. The isotherms of the mesoporous samples, specifically Al-MCM-41 and Al-MCM-41(F), were type IV, which is typical for mesoporous solids.…”

Toluene, Methanol and Benzaldehyde Removal from Gas Streams by Adsorption onto Natural Clay and Faujasite-Y type Zeolite

“…On the other hand, the degree of hydrophobicity is normally dependent on the Si/Al ratio. 55 Fau Y zeolite with high specific surface area (S BET ) making zeolite as an effective sorbent for pollution control purposes, especially for the removal of VOCs from waste gas streams.…”

Studies of C8 aromatics adsorption in BaY and mordenite molecular sieves using the headspace technique

“…Another method that has been more recently applied is the headspace chromatography (Torres et al 2001;Buarque et al 2005;Oliveira et al 2009), which allows the use of a much smaller quantity of liquid and higher solid to liquid ratio, thus increasing the magnitude of the change in concentration and the accuracy of the experimental results (Torres et al 2001). This technique consists in analyzing the composition of the vapor phase in equilibrium with the condensed phase of a mixture in a sealed vial containing the adsorbent sample.…”
