The benzene sorption capacity of as-synthesized and calcined MCM-41 and MCM-48 were compared. The hydrocarbon sorption capacity increases with pore diameter for the calcined versions. As-synthesized samples sorb appreciable amounts of benzene but the

The heat and entropy of benzene and hexane adsorption for AIPO 4 -ll, AIPO 4 -5, AIPO 4 -31, VPI-5, and SSZ-24 have been determined from adsorption isotherms. As the pore diameter decreases, the heat of adsorption and entropy change increase. This re

The benzene and triisopropylbenzene sorption capacity and rates of adsorption for several samples of MCM-41 and MCM-48 were compared. The results indicate that for samples with similar pore diameters, MCM-41 has approximately 30% more total capacity

The use of cationic surfactants as structure directing agents has resulted in the discovery of M41S, the first, ordered mesoporous molecular sieves. Herein we describe the ability of the surfactant molecules to interact with silicate counterions resu

1. Summary The influence of surfactant/silica molar ratio(Sur/Si) in M41S syntheses was studied in the simple synthesis system consisting of tetraethylorthosilicate(TEOS), water, and the cetyltrimethylammonium(CTMA) cation at 100°C. As the Sur/Si in
