EPG1/16 Inch Gas Industry 3A Molecular Sieve Desiccant

EPG1/16 Inch Gas Industry 3A Molecular Sieve Desiccant

Product introduction

3A Molecular Sieve, is an alkali metal alumina silicate. It is the potassium form of the type A crystal structure.It has an effective pore opening of about 3 angstroms(0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers.

4A Molecular Sieve, is an alkali alumina silicate. It is the sodium form of the type A crystal structure. It has an effective pore opening of about 4 angstroms(0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

5A Molecular Sieve, is an alkali alumina silicate. It is the calcium form of the type A crystal structure.It has an effective pore opening of 5 angstroms(0.5nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger.

13X Molecular Sieve, is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 10 Angstrom(1.0nm) and exclude those larger.

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.

Company information

Shanghai Xuefeng Molecular Sieve Co., Ltd. is a professional manufacturer of molecular sieve products, which belongs to Zhengzhou Xueshan Industrial Co., Ltd. Located in Shanghai Xinzhuang Industrial Zone, covering an area of 24 acer, it has nearly 7000 square meters of most standardized workshop, production equipment and testing instruments. At present, there are a series of stereotyped products such as type A (3a, 4a, 5a), X and so on, as many as 25 varieties have been put on the market.

The products are widely used in natural gas, oil refining, petrochemical, steel, light industry, air separation oxygen production and alcohol dehydration and other industrial fields, and have many successful examples in the deep drying, purification and separation of large and medium-sized industrial equipment at home and abroad. Xuefeng not only has many users in China, but also exports its products to developed countries such as Europe and the United States.

Shanghai Xuefeng has a certain scale of production, with three assembly lines with an annual output of more than 3000 tons of molecular sieves, and has passed the ISO9001-2000 standard Lloyd's quality management system certification, and Xueshanguan is a registered trademark of the product. In order to meet the needs of users, another automatic assembly line with an annual output of 6000 tons was installed in 2008.

Shanghai Xuefeng has introduced and digested the production technology of similar foreign products. The raw powder produced by our own Xueshan Industrial Company is added with clay strengthening agent. After kneading, roasting and activation, the appearance is beige or light gray. We can also produce strip and ball products of different specifications according to customer requirements. In accordance with the domestic (industry) standards of molecular sieves and referring to the main technical indicators of similar foreign products, Shanghai Xuefeng Molecular Sieve has formulated the technical standards for molecular sieve enterprises (QB/SF2690-99).The main testing items and indicators are shown in the sample. At the same time, eight types of molecular sieve products have been tested by Shanghai Research Institute of Chemical Industry ( the domestic molecular sieve national standard and industry standard drafting unit ) and other authoritative organizations, and all quality indicators have reached or exceeded relevant domestic and foreign technical standards.
