Molecular sieves: an alternative method of carbion dioxide removal

Demonstration of radon removal from SF6 using molecular sieves

The gas SF6 has become of interest as a negative ion drift gas for use in directional dark matter searches. However, as for other targets in such searches, it is important that radon contamination can be removed as this provides a source of unwanted background events. In this work we demonstrate for the first time filtration of radon from SF6 gas by using a molecular sieve. Four types of sieves...

Hydrodynamic Cavitation: An Alternative Method for Algae Removal from Water Resources

Enantiomerically enriched, polycrystalline molecular sieves.

Zeolite and zeolite-like molecular sieves are being used in a large number of applications such as adsorption and catalysis. Achievement of the long-standing goal of creating a chiral, polycrystalline molecular sieve with bulk enantioenrichment would enable these materials to perform enantioselective functions. Here, we report the synthesis of enantiomerically enriched samples of a molecular si...

Selective Carbon Dioxide Adsorption from N2- Ch4-co2 Mixture on Carbon Molecular Sieves

Cărbunii sită moleculară sunt adsorbanţi carbonici de o mare importanţă. Lucrarea prezintă rezultatele studiului privind prepararea cărbunilor sită moleculară şi modificarea tratamentului cu hidrocarburi care crachează. De asemenea se prezintă procesul de adsorbţie selectivă a dioxidului de carbon din amestecul N2-CH4-CO2 care se realizează într-un echipament special creat în acest scop, bazat ...

Ionothermal synthesis of aluminophosphate molecular sieves

Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...
