molecular sieve is a material with uniform-sized pores that selectively adsorb molecules based on their size and shape.

Use high activated alumina as material, Has certain pore structure and surface activity.

Use activated alumina ball as carrier, KMnO4 is a purple-black crystal, has high stability.

Carbon molecular sieve is an excellent adsorbent, its micropore affinity to oxygen molecules is strong, can be used to separate oxygen and nitrogen in the air.

Honeycomb zeolite molecular sieve is a combination of hydrophobic zeolite with different pore sizes, zeolite honeycomb structure has very excellent organic waste gas adsorption performance and good gas permeability.
