Faujasite - Wikipedia
Faujasite (FAU-type zeolite) is a mineral group in the zeolite family of silicate minerals. The group consists of faujasite-Na, faujasite-Mg and faujasite-Ca. They all share the same basic formula (Na 2,Ca,Mg) 3.5 [Al 7 Si 17 O 48]·32(H 2 O) by varying the …
Faujasite - an overview | ScienceDirect Topics
Introduction. Faujasite-type zeolites are one of the most important classes of zeolitic materials and are largely used in industrial processes such as FCC, isomerisation, alkylation and organics and air separation.
Template-free nanosized faujasite-type zeolites - Nature
Jan 5, 2015 · Nanosized faujasite (FAU) crystals have great potential as catalysts or adsorbents to more efficiently process present and forthcoming synthetic and renewable feedstocks in oil refining,...
Faujasite - SpringerLink
Jan 1, 2016 · FAU zeolites are generally synthesized by hydrothermal crystallization of reactive alkali metal aluminosilicate gels or clear solutions at low temperatures (70–300 °C, usually 100 °C) and pressure (autogenous) under alkaline conditions.
Faujasite | Zeolite, Volcanic, Silicate | Britannica
faujasite, hydrated sodium and calcium aluminosilicate mineral that is a rare member of the zeolite family. Faujasite somewhat resembles chabazite in chemical composition, crystal structure, and distribution.
Unlocking the Potential of Hidden Sites in Faujasite: New Insights …
Oct 14, 2021 · After almost 60 years of academic and industrial research, their resilience is unique as no other catalyst displaced them from key processes such as FCC and hydrocracking. The present study highlights the key difference leading to the exceptional catalytic performance of USY versus the parent zeolite Y in a multi-technique study combining ...

Samples and characterisation. The structure of Faujasite used in this study is characterised by a three dimensional pore network of large cavities of roughly spherical geometry (supercages with diameter around 12.5 Å) connected via windows to four others in a tetrahedral arrangement.
Potential Zeolites Related to Faujasite: Structures and Energetics ...
Aug 27, 2020 · We describe five new zeolitic framework types, fav, faw, fax, fay, and sod-t, that are structurally related to faujasite. They are derived from isomorphic expansions of the tetrahedral nets associated with selected Frank–Kasper phases.
