Zeolite 4A Description

molecular sieve beads are the potassium form of the Type A crystal structure with a pore opening of approximately 3 Ångstroms in diameter. The three dimensional pore structure will adsorb molecules up to 3 Ångstroms while excluding larger molecules such as unsaturated hydrocarbons and highly polar alcohols such as methanol and ethanol. The beads exhibit high mass transfer efficiency, high crush strength and durability.

Zeolite Usage

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.
