Basic Info
  • Material: Ceramic
  • Size: 4A
  • Specification: 4A
  • HS Code: 2842100000
  • Type: Random Packing
  • Trademark: TCI
  • Origin: Ningbo
Product Description
The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not adsorb any larger molecular than 4A, and often used as desiccant in industrials.

FORMULA: Na2O Al2O3 2.0SiO2 4.5H2O

TYPICAL APPLICATION
1) Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc.
2) Removal of hydrocarbons, ammonia and methanol from gas streams
(ammonia syn gas treating)
3) Special types are used in the air break units of buses, trucks and locomotives.
4) Packed in small bags, it may be used simply as a packaging desiccant.

REGENERATION
TCI molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; Or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 4A molecular sieve, a temperature of 250-280º C is required. A properly regenerated molecular sieve can give moisture dew points below -100º C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process

SIZE
4A - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh), 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.


ATTENTION
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
