Zeolite-filled silicone rubber membranes : Part 1. Membrane preparation and pervaporation results [PDF]
Amongst the alternative fuels obtained from renewable resources alcohol from fermentation may become one of the most important. The combination of fermentation with pervaporation in a membrane bioreactor offers the advantage of continuous processing.

Formation and characterization of inorganic membranes from zeolite-silica microcomposites [PDF]
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.

Species sensitivity of zeolite minerals for uptake of mercury solutes [PDF]
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.

Silicon aluminium ordering in the framework of zeolites [PDF]
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
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

Conducting polymer wires in mesopore hosts [PDF]
Nanometer-size conducting structures are of great interest in view of fundamental issues and potential applications. We explore the inclusion chemistry of conjugated polymers and graphite-like materials as a means to create such structures.

Cryogenic Hydrogen Adsorption onto H-, Li-, Na-Exchanged Zeolites with Various Si/Al Ratios
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 ...
