[EN] The structural, textural and acidic characteristics of hierarchical ZSM-5 (Si/Al = 18¿32), obtained with two
desilication approaches, and the effect of these treatments on the reactivity in various cracking reactions ...
[EN] This paper reports the activity of different Ce-BEA zeolites for the catalytic oxidation of trichloroethylene and it is focused on determining the nature of the catalyst active sites. The study was made by using a ...
The results of both chemical and XPS analysis pointed out that desilication of highly siliceous ZSM-5 of Si/Al = 164 was more effective in the surface zone than in the bulk, contrary to zeolite ZSM-5 of Si/Al = 31.6. ...
Highly siliceous zeolites, namely MFI type have attracted the great attention due to their higher hydrothermal stability, higher selectivity to organic compounds, and often better catalytic properties in comparison with ...

[EN] In this article the results of statistical MC modelling corroborated by the FT-IR spectroscopy and gravimetric adsorption studies of low aliphatic hydrocarbons in ZSM-5 (Si/Al = 28 or silicalite) are presented. The ...
Three Cu-zeolites with different structure, Cu-TNU-9, Cu-ITQ-2 and Cu Y have been tested as catalysts for propane oxidation reaction. The activity follows the trend: Cu-TNU-9 > Cu-ITQ-2 > Cu Y, and in situ electron ...
