High Quality Adsorbent Zeolite 5A Molecular Sieve

Short Description:

The aperture of molecular sieve 5A is about 5 angstroms, also called calcium molecular sieve. It can be used in the pressure swing adsorption instruments of oxygen-making and hydrogen-making industries。

The working principle of molecular sieves is mainly related to the pore size of molecular sieves, wThey can adsorb gas molecules whose molecular diameter is smaller than the pore size. The larger the size of the pore size, the greater the adsorption capacity. The pore size is different, and the things that are filtered and separated are also different.When used as a desiccant, a molecular sieve can absorb up to 22% of its own weight in moisture.

Zeolite molecular sieves have a unique regular crystal structure, each of which has a pore structure of a certain size and shape, and has a large specific surface area. Most zeolite molecular sieves have strong acid centers on the surface, and there is a strong Coulomb field in the crystal pores for polarization. These characteristics make it an excellent catalyst. Heterogeneous catalytic reactions are carried out on solid catalysts, and the catalytic activity is related to the size of the crystal pores of the catalyst. When a zeolite molecular sieve is used as a catalyst or a catalyst carrier, the progress of the catalytic reaction is controlled by the pore size of the zeolite molecular sieve. The size and shape of the crystal pores and pores can play a selective role in the catalytic reaction. Under general reaction conditions, zeolite molecular sieves play a leading role in the reaction direction and exhibit shape-selective catalytic performance. This performance makes zeolite molecular sieves a new catalytic material with strong vitality.
