ZSM-5 zeolite properties
Thermal stability
High thermal stability of ZSM-5 zeolite. This is caused by a
skeleton in a stable five-membered ring structure and a high silica
to alumina ratio. For example, the sample calcined at 850 ℃ After
2 hours, the crystal structure unchanged. Even can withstand high
temperature of 1100 ℃. So far, ZSM-5 zeolites are known to one of
the highest qualitative hot temperature. Therefore, it is used in
high-temperature process is particularly suitable. For example, use
it as a hydrocarbon cracking catalyst, regeneration of the catalyst
can withstand passage of time.
Acid resistance
ZSM-5 zeolite has good acid resistance, it is resistant to various
acids except hydrofluoric acid.
Steam stability
Wang, IKai other studies have shown that when other zeolites by
steam and hot water, and their general structure is destroyed,
leading to irreversible deactivation. The Mobil company with ZSM-5
as the conversion of methanol (water is one of the major product)
catalyst. This suggests that ZSM-5 to water vapor with good
stability. 540 ℃ lower partial pressure of 22mmHg steaming column
and HY zeolite HZSM-5 after 24 hours, a crystallinity of HZSM-5 and
about 70 percent of fresh catalyst, but under the same conditions,
HY zeolite skeleton almost completely damage.
Hydrophobic
ZSM-5 having a high silica to alumina ratio, the smaller the
surface charge density. The water molecule is polar, so you will
not ZSM-5 is adsorbed. Although water molecules smaller than the
diameter of n-hexane, but the amount of adsorption of n-hexane
ZSM-5 is generally greater than water.
