Zeolite Structures |
|
|
|
Zeolites (Greek, zein, "to boil"; lithos, "a
stone") are hydrated aluminosilicate minerals and have
a micro-porous structure.
More than 150 zeolite types have been synthesized and 48 naturally
occurring zeolites are known. Zeolites have an "open"
structure that can accommodate a wide variety of cations, such
as Na+, K+, Ca2+, Mg2+ and others. These positive ions are rather
loosely held and can readily be exchanged for others in a contact
solution. Some of the more common mineral zeolites are: analcime,
chabazite, heulandite, natrolite, phillipsite, and stilbite.
An example mineral formula is: Na2Al2Si3O10-2H2O, the formula
for natrolite.

| What is Zeolites
Y |
|
 |
zeolite catalyst of ultrastable Y-type (USY) was investigated
in the research of two staged pyrolysis¨Ccatalysis of scrap tyres.
Scrap tyres were pyrolysed in a fixed bed reactor and the evolved
pyrolysis gases were passed through a secondary catalytic reactor.
The main objective of this paper was to investigate the effect
of zeolite USY on the yield of products and the composition
of derived oil. The influences of several parameters such as
pyrolysis temperature, catalytic temperature, catalyst/tyre
ratio, heating rate, etc. on the yield of the derived oil, char
and gas were investigated. It showed that the increase of catalytic
temperature and catalyst/tyre ratio resulted in high yield of
gas at the expense of the oil field.

Zeolites are used by everyone in the world. Many people may
not have a lot of experience with zeolites but would like to
learn more. For these people, Anten Chemical has posted answers
to some commonly asked questions about zeolites as an introduction
to what zeolites are and what they do in real-world applications.
