3A Activated Molecular Sieve-Spherical & Bar shape
3A Activated Molecular Sieve-Spherical & Bar shape
Introduction & Specs
| Introduction | 3A molecular sieve is an alkali metal aluminosilicate with a pore size of 3Å and a potassium-type A-type crystal structure. It is primarily used for water adsorption and does not adsorb any molecules larger than 3Å. It is the preferred desiccant for deep drying, refining, and polymerization in the petroleum and chemical industries.
|
| Benefits | l Fast adsorption rat
l More regeneration times l Higher crushing strength l Stronger anti-contamination ability l Greater utilization efficiency l Longer service life, etc.
|
| Applications | l Mainly used for drying unsaturated hydrocarbons such as ethylene, propylene, butadiene, and other petroleum cracking gases.
l Drying polar liquids such as methanol and ethanol. l Drying air. l Drying natural gas and methane.
