Gas separation by employing polymeric membranes is one of the most developed branches
of membrane based separation technology. But, polymeric materials are unable to meet the …

Nowadays, membrane technologies are essential to a wide range of commercial
applications in petrochemical, chemical, food, pharmaceutical, semiconductor …

USY zeolite was treated by the citric acid. The properties and catalysis of the USY zeolite
were studied. The X-ray diffraction has been used to identify and quantify extra framework …

This review summarizes the importance of nanoporous materials and their fascinating
structural properties with respect to the catalytic and photocatalytic reduction of CO2 to …

In this work, Al-SBA-15 samples with different Si/Al ratios were synthesized; Al was
incorporated in the mesoporous SBA-15 structure either using the direct synthesis method …

Removal of organic sulfur compounds from its solution has been investigated by using
adsorption on the ion-exchanged Y zeolites. Effects of metal cations, calcination temperature …

A palladium-nickel doped sulfated zirconia was prepared, and hydrogen spillover and
bimetallic synergic effect were confirmed using this model catalyst. Isomerization of n …

This work mainly involved the investigation of the adsorption of thiophene on Cu (I)-
supported HY-Al2O3. It demonstrated a high sulfur capacity of 10 mg sulfur/g sorbent when …

The commercial clay modified with zeolite and La2O3 was characterized by
thermoprogrammed desorption (tpd) of NH3 and pyridine adsorption followed by Fourier …

This work mainly involved the investigation of the adsorption of propylmercaptan (PM) on
modified bentonite adsorbents. The adsorbents were prepared by loading it separately with …
