Types of Molecular Sieves

types of molecular sieves.

Molecular sieves are porous materials that are used for various applications, including gas separation, dehydration, and purification. Here is a list of several types of molecular sieves:

1. Zeolite 3A (type A): Used for selective adsorption of water, carbon dioxide, and small molecules.

2. Zeolite 4A (type A): Suitable for drying and removal of water, carbon dioxide, and hydrogen sulfide.

3. Zeolite 5A (type A): Offers excellent absorption properties for water, carbon dioxide, and larger molecules.

4. Zeolite 13X: Effective in adsorbing water, carbon dioxide, hydrogen sulfide, and various other molecules.

5. Zeolite Y: Suitable for drying, purification, and adsorption of larger molecules and organic compounds.

6. Zeolite ZSM-5: Used primarily for shape-selective catalysis and hydrocarbon cracking.

7. Molecular Sieve 4Å: Offers high adsorption capacity for water and small molecules.

8. Molecular Sieve 10Å: Typically used for nitrogen, oxygen, and noble gas separation.

9. Molecular Sieve 13X: Suitable for dehydration and purification of various gases.

10. Silicoaluminophosphate (SAPO-5): Used for selective adsorption of carbon dioxide and light hydrocarbons.

11. Silicoaluminophosphate (SAPO-34): Known for selective adsorption of olefins and carbon dioxide.

12. Silicoaluminophosphate (SAPO-40): Used for selective adsorption of carbon dioxide and separation of light hydrocarbons.

13. Aluminophosphate (FeAPO-5): Suitable for selective adsorption of carbon dioxide over nitrogen.

14. Aluminophosphate (CoAPO-5): Exhibits high selectivity for transporting nitrogen.

15. Titanium Silicalite-1 (TS-1): Known for its catalytic properties in oxidation reactions.

16. Aluminium Phosphates: Used for selective adsorption and separation of various molecules.

17. Titanium Beta Zeolites: Suitable for catalytic applications such as alkylation and epoxidation.

This is not an exhaustive list, but it covers some of the commonly used molecular sieves.
