2.5mm 26N 13X Molecular Sieve Adsorbent
Commonly used adsorbents include various activated carbon
adsorbents and metal and non-metal oxide adsorbents (such as silica
gel, alumina, molecular sieve, natural clay, etc.) using carbon as
The main indicators to measure the adsorbent are: adsorption
capacity for different gas impurities, abrasion rate, loose bulk
density, specific surface area, crush strength, etc. It is used to
filter out poisonous gas, refine petroleum and vegetable oil,
prevent viruses and molds, recover gasoline in natural gas, and
decolorize sugar and other colored substances.
The adsorbents commonly used in industry are: silica gel, activated
alumina, activated carbon, molecular sieves, etc. In addition,
there are adsorption materials developed for selective adsorption
of certain components. The success of gas adsorption and separation
largely depends on the performance of the adsorbent. Therefore, the
choice of adsorbent is the primary issue in determining the
Molecular Sieve 13X: 13x Molecular Sieve is a special product which is produced to meet
the special requirements of air separation industry.It further
enhances the adsorption capacity for carbon dioxide and water,and
also avoids tower frozen during air separation process.It also can
be used for oxygen-making.

Scope of application
1. Separation of enriched oxygen from air.
2. Production of medical or bulk oxygen in PSA units.
3. Removal of co2 and moisture from air (air pre-purification)and
4. Catalyst protection , removal of oxygenates from
5. Removal of mercaptans and hydrogen sulphide from hydrocarbon
liquid streams such as LPG, butane, propane etc.
Molecular sieve models commonly used in the gas industry;
Type A: Potassium A (3A), Sodium A (4A), Calcium A (5A), Type X:
Calcium X (10X), Sodium X (13X)
Type Y: Sodium Y, Calcium Y
Molecular sieve has strong moisture absorption capacity and is used
for gas purification treatment. Avoid direct exposure to the air
during storage. Molecular sieves that have been stored for a long
time and have absorbed moisture should be regenerated before use.
Molecular sieve avoids oil and liquid water. Try to avoid contact
with oil and liquid water when in use. The gases to be dried in
industrial production include air, hydrogen, oxygen, nitrogen,
argon, etc. Two adsorption dryers are used in parallel, one works,
and the other can be regenerated. Alternate work and regeneration
to ensure continuous operation of the equipment. The dryer works at
8-12°C, and regenerates when heated to 350°C. Different
specifications of molecular sieve have slightly different
regeneration temperatures. Molecular sieves have a good catalytic
effect on certain organic gas phase reactions.
1. Adsorption is selective.
⑴ Choose the adsorption according to the different molecular
⑵ Select the adsorption according to the polarity of the molecule.
⑶ Selective adsorption according to the degree of molecular
⑷ Select adsorption according to different boiling points.
2. It has low concentration and high adsorption characteristics at
3. Cation exchange characteristics.
4. Catalytic properties.
⑴ The heterogeneous catalytic reaction is carried out on the
surface of the catalyst. When the molecular sieve is used as a
catalyst or carrier, the catalytic reaction is to catalyze the
substances entering the micropores of the molecular sieve.
⑵ Only produce products whose molecules are smaller than the pores
of the molecular sieve.
⑶ Because of the large surface area, it has high activity.
⑷ Strong resistance to poisoning and high thermal stability.
⑸ When used as a carrier, the metal catalyst can be evenly
distributed on the inner surface of the molecular sieve, so it is
easy to prepare a catalyst with good repeatability.
