Preparation of Sodalite and Faujasite Clay Composite Membranes and Their Utilization in the Decontamination of Dye Effluents

open access: yesMembranes, 2021
The present work describes the deposition of two zeolite films, sodalite and faujasite, by the hydrothermal method to tune the mesopores of clay support, which are prepared from a widely available clay depot from the central region of Morocco (Midelt ...

Oxidative Dehydrogenation of Propane over Vanadium-Containing Faujasite Zeolite

open access: yesMolecules, 2020
Oxidative dehydrogenation (ODH) of light alkanes to olefins—in particular, using vanadium-based catalysts—is a promising alternative to the dehydrogenation process.

UV-light assisted synthesis of high silica faujasite-type of zeolites [PDF]

open access: yes, 2022
Currently, the direct synthesis of faujasite-type (FAU) zeolites with Si/Al ratios greater than 3 depends on organic or inorganic additives. Here, we report the first additive-free synthesis of faujasite with Si/Al ratios greater than 3 using ultraviolet

Molecular Dynamics of Alkanes in Faujasite Zeolites [PDF]

open access: yes, 1998
Molecular dynamics simulations of C1 through C14 n-alkanes have been used to elucidate diffusion mechanisms in siliceous faujasite zeolites. Additional simulations of the bulk liquids were conducted to compare the liquid and adsorbed phases.

Quasi Natural Approach for Crystallization of Zeolites from Different Fly Ashes and Their Application as Adsorbent Media for Malachite Green Removal from Polluted Waters

open access: yesCrystals, 2020
Worldwide disposal of multi-tonnage solid waste from coal-burning thermal power plants (TPPs) creates serious environmental and economic problems, which necessitate the recovery of industrial waste in large quantities and at commercial prices. Fly ashes (

Utilização de zeólitas sintetizadas a partir de xisto retortado na remoção de arsênio em águas contaminadas Use of zeolites synthesized from oil shale ash for arsenic removal from polluted water

open access: yesQuímica Nova, 2007
The solid by-product of the oil shale processing (PETROBRAS - Brazil) was used as raw material to synthesize zeolites A and faujasite. Alkaline fusion followed by hydrothermal treatment was the synthesis procedure used, and five different starting ...
