Strong Anti Pressure Adsorbent 3A Molecular Sieve Desiccant For Butene Butadiene Catalyzing
Product Description of 3A Molecular Sieve Desiccant
The pore size is between 3 and 10. Zeolite molecular sieve has large pores on the inner surface, which can adsorb and store a large number of molecules, so the adsorption capacity is large; the pore size is neat and uniform, and it is an ionic adsorbent with strong adsorption selectivity; at higher temperatures and lower partial pressures It can still maintain strong adsorption capacity for some polar molecules. Widely used in drying, separation, etc. Zeolite molecular sieve is an inorganic crystalline material. It is widely used in catalysis, adsorption and ion exchange due to its regular pore structure, strong acidity and high hydrothermal stability, and plays an irreplaceable role.
Zeolite molecular sieve is a family of crystalline silicon aluminate salts. The most basic structure of zeolite is composed of (SiO4) tetrahedron and (AlO4) tetrahedron. Adjacent tetrahedrons are connected by oxygen Bridges to form rings, which are big and small. According to the number of oxygen atoms forming rings, there are four oxygen rings, five oxygen rings, six oxygen rings, eight oxygen rings, ten oxygen rings and twelve binary oxygen rings. Ring is the channel orifice of molecular sieve, sieve through the molecular sieve. Oxygen rings are connected by oxygen Bridges to form polyhedra with three dimensional space. Polyhedra have hollow cages, which are important characteristics of molecular sieve structure. The cavity contains water of crystal and cations, which neutralize the negative charge of the tetrahedron (AlO4). Some or all of the water of crystal can be relatively easily removed by means of heating or decompression.
