Product introduction

Molecular sieve is a cubic lattice silicon aluminate compound.The microporous structure of the molecular sieve is uniform, and its cavity diameter size uniform, can the cavity is smaller than the diameter of the molecular adsorption to the interior of the pore space, and the polar molecules and unsaturated molecules have preferential adsorption ability, thus can bring a different polarity degree, degree of saturation is different, different molecular size and the boiling point of different molecular separation, which have the function of the "screening" molecules, molecular sieve, therefore calls due to the molecular sieve has high adsorption ability, strong thermal stability and other advantages of adsorbent is not makes the molecular sieve to obtain a wide range of applications.

Molecular sieve has two kinds of natural zeolite and synthetic zeolites.Most of the natural zeolite by volcanic tuff and gray matter in the Marine sedimentary rocks coagulation or react to form in the lacustrine environment.Has been found that there are more than 1000 zeolite ore, more important is 35, common clinoptilolite and mordenite, erionite and ling zeolite, etc.

Molecular sieve purposes

Molecular sieve used for oil cracking gas, olefins, gas plant, oil field gas drying, such as chemical, pharmaceutical, hollow glass desiccant used in industry.Used in natural gas and various chemical gases and liquids, refrigerant, medicine, electronic materials and volatile matter of dry, argon gas purification and separation of methane, ethane, propane.

1) Removal of CO2 and moisture from air (air pre-purification) and other gases.
2) Separation of enriched oxygen from air.
3) Removal of mercaptans and hydrogen sulphide from natural gas.
4) Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams
5) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
6) Removal of n-chained compositions from aromatics.
7) Production of bulk oxygen in PSA units .
8) Production of medical oxygen in small scale oxygen concentrators

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.
