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

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 ...
