Water Removal 8×12 Mesh 13X Molecular Sieve Adsorbent

Product introduction

Molecular sieve is a kind of aluminosilicate compound with cubic lattice. It mainly consists of aluminosilicate connected by oxygen bridge to form an empty skeleton structure. In the structure, there are many uniform pore channels and well-arranged holes with large inner surface area. In addition, it contains metal ions with lower electricity price and larger radius of ions and hydrated water. Because the water molecule loses continuously after heating, but the crystal skeleton structure remains unchanged, many cavities of the same size are formed, and the cavities are connected by many micro-holes of the same diameter. These micro-holes are uniform in diameter and can absorb molecules smaller than the diameter of the channel into the inside of the hole, while larger molecules than the channel. Because of exclusion, molecules with different shapes and diameters, polarity, boiling point and saturation can be separated, which is called molecular sieve.

13X molecular sieve is of the type X crystal, as opposed to the type A crystal of the 3A, 4A, and 5A molecular sieves. However, the 13X molecular sieve is similar to the 4A in that it has sodium ion (Na+) in its structure. The different types of the crystal affect the size of the pore opening. Where the 4A molecular sieve has a 4 angstrom pore opening, the 13x molecular sieve has a 10 angstrom pore opening.

Product Performance

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.

Product Features

1. Adsorption is selective.

⑴ Choose the adsorption according to the different molecular diameter.

⑵ Select the adsorption according to the polarity of the molecule.

⑶ Selective adsorption according to the degree of molecular unsaturation.

⑷ Select adsorption according to different boiling points.

2. It has low concentration and high adsorption characteristics at higher temperature.

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.
