4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O ₃
The working principle of molecular sieve is mainly related to the pore size of molecular sieve, which can adsorb gas molecules whose molecular diameter is smaller than the pore size, and the larger the pore size, the larger the adsorption capacity. The size of the aperture is different, and the filtered things are different. 4a molecular sieve, the adsorbed molecules must also be less than 0.4nm
4A molecular sieves are mainly used to dry natural gas and various chemical gases and liquids, refrigerants, drugs, electronic data and volatile substances, purify argon, and separate methane, ethane and propane. Mainly used for deep drying of gases and liquids such as air, natural gas, hydrocarbons and refrigerants; Preparation and purification of argon; Static drying of electronic components and perishable materials; Dehydrating agents in paints, polyesters, dyes and coatings.
13X type molecular sieve, also known as sodium X type molecular sieve, is an alkali metal silicaluminate, has a certain alkaline, belongs to a class of solid bases.
Its chemical formula is Na2O· Al2O3·2.45SiO2·6.0H20,
Its pore size is 10A and it adsorbs any molecule greater than 3.64A and less than 10A
The 13x is mainly used in:
1) Gas purification in the air separation device to remove water and carbon dioxide.
2) Drying and desulfurization of natural gas, liquefied petroleum gas and liquid hydrocarbons.
3) General gas depth drying. 13X type molecular sieve, also known as sodium X type molecular sieve, is an alkali metal silicaluminate, has a certain alkaline, belongs to a class of solid bases.
