High Purity APG1/8" 13X Molecular Sieve Desiccant

High Purity APG1/8" 13X Molecular Sieve Desiccant

Product introduction

13X molecular sieve has a pore size of 10A, which can adsorb molecules smaller than 10A. Any molecule that can be adsorbed on 3A, 4A, and 5A molecular sieves can be adsorbed by 13X. It can be used for catalyst carrier, water and carbon dioxide co-adsorption, water and hydrogen sulfide gas co-adsorption, It is mainly used in the drying of medicine and air compression systems. There are different professional varieties according to different applications. 13X-APG special molecular sieve for air separation is a special molecular sieve produced to meet the special requirements of the cryogenic air separation industry, further improve the adsorption capacity of molecular sieve for carbon dioxide and water, and avoid freezing tower phenomenon in the air separation rectification process. This product is suitable for For cryogenic air separation devices of various sizes.

A main component of X-type molecular sieve is aluminosilicate, silicon-oxy and alumina tetrahedron to form a FAU-type structure the main crystal structure is twelve membered rings.

In molecular sieve 13X, sodium ion formation with a pore opening of 9-10Å (1Å=1×10-10m), that is type 13X (also known as NaX-type) molecular sieve.

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.
