Xylene isomerization in a ZSM-5/SS membrane reactor
(Springer, 2008-06)
A membrane reactor containing different types of ZSM-5/porous SS membranes was used to perform the xylene isomerization reaction. The parent Na-ZSM-5 layer was synthesized by secondary growth on top of porous stainless ...
Synthesis and characterization of MCM-48 tubular membranes
(Elsevier Science, 2006-09)
MCM-48 membranes have been prepared on alumina supports of different pore sizes. A battery of characterization techniques has been used to study the physical properties and the quality of the membranes prepared. The highest ...
Improving Nafion/zeolite nanocomposite with a CF3SO3- based ionic liquid for PEMFC application
(2021-05-01)
Nafion/zeolite/ionic liquid composite membranes were prepared by the casting method. A fixed 3 wt% of the HZSM-5 zeolite was added to the polymer as well as the C16MI.CF3SO3 ionic liquid (IL) in various amounts in the range ...
Preparation of stable MCM-48 tubular membranes
(Elsevier Science, 2009-01)
Stable mesoporous membranes with a cubic structure, based on the MCM-48 material, were successfully prepared on alumina supports by hydrothermal synthesis, starting from sols having both CTABr and TPAOH structure directing ...
Microporous titanosilicate ETS-10 membrane for high pressure CO2 separation
(Elsevier Science, 2010-05)
Membrane technology is expected to be an efficient process for CO 2 separation. Microporous titanosilicate ETS-10 membranes prepared by seeded hydrothermal synthesis are presented as candidates to CO2 separation from binary ...
Synergy gas separation effect when using fillers of different natures (MOF and zeolites) in the same mixed matrix membrane
(Elsevier, 2012-08)
The incorporation of inorganic or hybrid fillers such zeolites or metal organic frameworks (MOFs) into polymeric membrane materials in the for of mixed matrix membranes (MMMs) has become an increasingly important field of ...
A simple synthesis procedure to prepare nanosized faujasite crystals
(Elsevier Science BvAmsterdamHolanda, 2012)
Influence of exchanged cations (Na+, Cs+, Sr2+ and Ba2+) on xylene permeation through ZSM-5/SS tubular membranes
(Elsevier Science, 2008-07)
Na-ZSM-5 membranes were synthesized by secondary growth on the outer surface of stainless steel porous tubes. The membranes were ion-exchanged with Cs+, Ba2+ and Sr2+ to investigate their effect upon the separation of ...
