Inhibition of the hydrogenation of tetralin by nitrogen and sulfur compounds over Ir/SBA-16
(2011)
In this work we study the catalytic properties of 5 wt.% Ir-containing SBA-16 catalysts (with and without aluminum as heteroatom), in the hydrogenation of tetralin to decalin, in the presence of 100 ppm of N as quinoline, ...
XANES-PCA analysis of Ti-species in MCM-41 mesoporous silica synthesized by different methods
(2011)
MCM-41 mesoporous silica was prepared with Ti incorporated in the structure by two different ways: hydrothermal and atmospheric pressure by sol–gel method. To evaluate each synthesis, these materials were in situ investigated ...
Hydrogenation of tetralin over Ir-containing mesoporous catalysts
(2012)
The yield in fluid catalytic cracking (FCC) depends on the
extent of aromatic hydrogenation in the gas oil hydrotreater. To optimize the gas oil hydrotreater, it is crucial to understand the aromatic hydrogenation reaction ...
Synthesis of ordered mesoporous SBA-3 materials using silica gel as silica source
(2014)
Nanostructured materials have exceptional and highly attractive properties, including catalyst, adsor- bent, separation media and chemo sensor. Technical advances in these fields require the development of ordered porous ...
Synthesis and characterization of new composites: PANI/Na-AlSBA-3 and PANI/Na-AlSBA-16
(2011)
The new aluminosilicate materials (Na-AlSBA-3 and Na-AlSBA-16) were synthesized for application in the preparation of composites. Silica mesoporous materials were obtained following the sol–gel method and post-synthesis ...
Hydrogenation of tetralin over Ir catalysts supported on titania-modified SBA-16
(2014)
Abstract A series of Ti modified SBA-16 supports and their respective Ir-catalysts were prepared and character- ized to study the effect of support preparation method on the dispersion of iridium and on the characteristics ...
Synthesis and characterization of conducting polypyrrole/SBA-3 and polypyrrole/Na–AlSBA-3 composites
(2012)
Si-SBA-3 and Na–AlSBA-3 materials were synthesized for application in the preparation of composites. Silica mesoporous materials were obtained following the sol–gel method and post-synthesis alumination. Pyrrole-saturated ...
Hydrodenitrogenation of indol using iridium catalyst supported on titanium nanotubes
(2022)
The HDN of indole was studied over iridium modified titanate nanotube catalyst. Titaniun nanotube
was prepared by the alkaline hydrothermal method. Iridium was added by wetness impregnation.
The activity was compared ...
HDT of the model diesel feed over Ir-modified Zr-SBA-15 catalysts
(2018)
Iridium catalyst using different zirconium modified-SBA-15 supports were tested in the HDT of tetralin and typical sulfur and nitrogen compounds present in diesel feed. The zirconium modified-SBA-15 supports were synthesized ...
Catalytic oxidation of sulfur compounds over Ce-SBA-15 and Ce-Zr-SBA-15
(2021)
The catalytic oXidation of different sulfur compounds, commonly present in liquid fuel, was studied over a series of ceria and ceria-zirconium based oXidation mesoporous catalysts. SBA-15 was synthesized using sol-gel ...
