Adsorption of carbon dioxide and nitrogen on silica lite-1 and M41S type materials
2005Abstract The ability of silicalite-1 and M41S type materials to adsorb pure CO 2 and N 2 has been experimentally studied by determining the adsorption isotherms at 20°C. The experimental data have been analyzed using the Langmuir and Freundlich adsorption isotherm models.

Development of a formation mechanism for M41S materials
19941. 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 increased from 0.5 to 2, the siliceous products obtained were identified and could be classified into ...

The discovery of ExxonMobil's M41S family of mesoporous molecular sieves
2004Publisher Summary This chapter discusses the discovery of ExxonMobil's M41S family of mesoporous molecular sieves. The quest for new molecular sieves in the late 1980's led a team of mobil researchers to the discovery of a family of nanostructured mesoporous materials known as “M41S.” Mobil composition of matter (MCM)-41, the hexagonal phase, is ...

Development of Conceptual Designs for an Improved M41 Type Space Heater
1984Abstract : This report describes an effort to develop conceptual designs for a new improved M41 type space heater. The design features of the current M41 were evaluated and ranked in order of importance. A literature search was performed to base possible design improvements using technology which was not available when the M41 was initally developed ...
