Product Name
Name:A Molecular Sieve
Product Overview
Zeolite molecular sieve is a kind of crystalline aluminum silicate metal salt hydrate with microporous structure. It has the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes can play the role of adsorbing molecules. The holes are connected with each other, and the molecules pass through the holes. The pore size distribution of zeolite molecular sieve is very uniform, which can be divided into microporous, mesoporous and biporous zeolite according to its pore or channel system. Its adsorption has two characteristics: the Lewis center on the surface has a strong polarity: The Lewis center on the surface of the zeolite molecular sieve has a strong polarity and can strongly interact with the adsorbent molecules. The size of the cage or channel in zeolite is very small, which makes the gravitational field of it very strong: this makes the adsorption capacity of zeolite molecular sieve to adsorbent molecules far more than other types of adsorbents, even if the partial pressure (or concentration) of the adsorbent is very low, the adsorption amount is still considerable. Zeolite molecular sieve can selectively adsorb molecules according to the size of pores in the crystal, and can be used in adsorption, separation, catalysis and other fields. For example, in the petrochemical industry, zeolite molecular sieve can be used for catalytic cracking, hydrocracking and other reactions; In environmental protection, it can be used for wastewater treatment, waste gas purification, etc. In the field of medicine, it can be used for drug separation and purification.

Product Features
Selective adsorption: 3A molecular sieve has a pore size of 3A, which is mainly used to adsorb water and cannot adsorb any molecule with a diameter greater than 3A.
Efficient drying: 3A molecular sieve has a strong adsorption capacity for water, which can effectively remove water in gases or liquids.
Good stability: good chemical stability and thermal stability.
Renewable: The regeneration and reuse of molecular sieve can be achieved through appropriate methods.
Application Fields
Air separation: used for air drying and purification.
Petroleum refining: plays a role in the drying process of petroleum cracking gas, ethylene, propylene, etc.
