type:
Molecular Sieve 13X
model:
13X
supplier:
Pingxiang Longhua Chemical Packing Co., Ltd
brief product description:
Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 9 Angstrom (0.9 nm) and exclude those larger.

Regeneration:
XINTAO molecular sieve Type 13X 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 molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptan or CO2 levels below 2 ppmv.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
Package:
30kg or 25kg carton box, inside bag vacuum packing
Or 120kg-150kg iron drum, inside bag vacuum packing
Other packages request by the customers.
Attention:
Do not unpack the goods until using, avoid of exposure in air for a long time. Should be stuffed as rapid as possible at filling, or it should be reactivated before running.
