China New Product Platinum Alumina Catalyst - Molecular Sieve 5A – Ton Year

Introduction
Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.
It is especially suitable for PSA adsorber applications where it may be used for the separation of normal and iso-paraffins (C4to C6 species), in PSA hydrogen purification and in oxygen concentrators.

Technical Parameter

Size Regeneration
Molecular sieve Type 5A 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 5A molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or merca ptan or CO2 levels below 2 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

5A – Zeolites are available in beads of 1-2 mm(10×18 mesh), 2-3 mm(8×12 mesh), 2.5-5 mm(4×8 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.
