Products Introduction
13X-APG zeolite is a special zeolite produced to meet the special requirements of the cryogenic air separation industry, further improve the adsorption capacity of carbon dioxide and water, and avoid the phenomenon of freezing tower in the air separation process. It can also be used for oxygen enrichment. At the same time can be used in the air separation plant gas purification, removal of water and carbon dioxide, natural gas, liquefied petroleum desulfurization, general gas deep drying.

Regeneration
Molecular Sieve Type 13X APG 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 13X APG molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptans or CO2 levels below 2ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
Size
13X APG- Zeolite are available in beads of 1-2mm (10x18 mesh), 2-3mm (8x12 mesh), 2.5-5mm (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.
