Formation and characterization of inorganic membranes from zeolite-silica microcomposites [PDF]
, 1988 Small crystals of zeolites (500-1000 nm) with two- and three-dimensional channel systems (faujasite and ZSM-5 structures) were embedded in amorphous thin films derived from TEOS hydrolyzed in alcoholic solution.

Silicon aluminium ordering in the framework of zeolites [PDF]
Bulletin of the Geological Society of Finland, 1985 The (Si, Al) ordering scheme in the framework of zeolites is reviewed, and four classes are recognized: 1 ‒ zeolites with Si:Al = 1 : 1 and a simple order given by the alternation of Si and Al; 2 ‒ zeolites with Si> Al and an ordered distribution; 3 ...

Benzene Alkylation by Ethanol over Catalysts on the Base of Modified Natural Zeolites
Eurasian Chemico-Technological Journal, 2012 Alkylation of aromatic compounds with ethanol was researched on modified natural zeolites of Kazakhstan deposits. These natural zeolites were identified as Clinoptilolite-Heulandite type. Zeolites were treated by hydrochloric acid, which leads to removal

Species sensitivity of zeolite minerals for uptake of mercury solutes [PDF]
, 2006 The uptake of inorganic Hg2+ and organometallic CH3Hg+ from aqueous solutions by 11 different natural zeolites has been investigated using a batch distribution coefficient (Kd) method and supported by a preliminary voltammetric study.

Interaction between zeolites and cluster compounds. Part 1.—Adsorption of iron pentacarbonyl on zeolites [PDF]
, 1983 The adsorption isotherms of Fe(CO)5 on NaY, HY and Linde L zeolites obtained in McBain balances show micropore adsorption, whereas additional capillary condensation is found with zeolite omega and Na-mordenite.

Characterization of natural Yemeni zeolites as powder sorbents for ammonium valorization from domestic waste water streams using high rate activated sludge processes [PDF]
, 2018 BACKGROUND In this study three natural Yemeni zeolites (NZ1, NZ2 and NZ3) having major minerals such as clinoptilolite and mordenite, were evaluated as low cost sorbents for the removal and recovery of ammonium ions.

Cryogenic Hydrogen Adsorption onto H-, Li-, Na-Exchanged Zeolites with Various Si/Al Ratios
Adsorption Science & Technology, 2014 We investigated the hydrogen-adsorption properties of four zeolites (FAU-, MFI-, *BEA- and MOR-type zeolites) with various Si/Al ratios and charge cations (H + Li + or Na + ), focusing particularly on the measurements of isosteric heat of adsorption (Q ...
