Product introduction

In a narrow sense, it is a silicate molecular sieve or crystalline aluminosilicate, and the formation of silicon-oxygen tetrahedron molecular sieve or aluminum oxide tetrahedra connected through an oxygen bridge.

Molecular size (normally 0.3 ~ 2.0 nm) of the pore and cavity system, which has a molecular sieving characteristics. However, with the further molecular sieve synthesis and applied research, the researchers found that the aluminophosphate molecular sieves and sieve skeleton elements (silicon or aluminum or phosphorus) may be composed of B, Ga, Fe, Cr, Ge, Ti, V , Mn, Co, Zn, be and Cu, replaced its channels and cavity size may also reach 2 nm or more, the zeolite framework elements can be divided according to aluminosilicate molecular sieves, aluminum phosphate molecular sieves and sieve framework heteroatom ; divided by pore size, pore size of less than 2 nm, 2 ~ 50 nm and 50 nm, respectively, greater than the molecular sieve called micropores, mesopores and large pore molecular sieve. Because of the larger aperture, the larger size molecules become good reaction carrier, but the pore walls of mesoporous materials are amorphous, resulting in the hydrothermal stability and thermal stability can not meet the desired petrochemical applications harsh conditions .

Low electrovalence and because it contains a large ionic radius of water, heating the water molecules in the continuous loss of metal ions and compounds of state, but the same crystal framework structure, the formation of many of the same size of the cavity, the cavity diameter there are many connected to the same microporous, these tiny cavities diameter uniform size, can smaller than the pore diameter of molecules adsorbed to the interior of the cavity, and the larger pores than the molecular exclusion, different shapes can thus molecular diameters, different degrees of polar molecules, the boiling point of different molecules, different saturation levels of molecules separated, that has the effect of "screening" of molecules, so called molecular sieves. Currently zeolite is widely used in metallurgy, chemical industry, electronics, petrochemical and natural gas industries.

Regeneration
1. Removal of water: it depends on the pressure, temperature and water content of the regeneration gas. Under normal circumstances, the dry gas at 200~350℃ will pass through the molecular sieve bed for 3~4 hours under the pressure of 0.3~0.5kg/cm to bring the outlet temperature to 110~180℃ and cool.
2. Removal of organic matter: replace organic matter with water vapor, and then remove water.
 
 
Package
Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.
