13X Molecular
Sieve
Introduction
Molecular Sieve 13X is the sodium form of the
type X crystal and has a much larger pore opening than the type A
crystals.The pore size 13X molecular sieve is about 10 Å . It can adsorb
any molecular smaller than 10 Å , mainly used as catalyze carrier,
co-adsorption of CO2
and H2O, H2O
and H2S, as desiccant for medical and air
compressor system, and can also be adjusted to fit other various
applications.
Application
Molecular Sieve 13X is mainly used for refinement since
it implements simultaneous absorption for bi-molecule and tri-molecule
and can be applied for liquefied and gaseous materials on the whole.
Main adsorbing target are carbon dioxide, sulfuretted hydrogen and
mercaptan including water and it can adsorb all the material whose
molecular diameter is less than 10A.
Will adsorb, in sequence of adsorption rate, SF6, CHCL3, CHBr3, CHI3,
N-C3F8, CCL4, N-C4F10, N-C7H16, CBr4, C6H6, B5H10, (CH3)3N, C(CH4)4,
(C2H5)3N, C(CH3)C3CL, C(CH3)3Br, and C(CH3)3CH.The main uses are as follows.
1) Air refining (removing CO2 and H2O)
2) Removal of mercaptans and hydrogen sulphide from natural gas
using patented Zeochem technology
3) Removal of mercaptans and hydrpogen sulphide from hydrocarbon
liquid streams (LPG, butane, propane etc.)
4) Oxygen PSA (Pressure Swing Adsorption) process
5) special double glass (removing solvent and grease)

Regeneration
Molecular Sieve Type 13X can be regenerated by
evacuating or purging, usually at elevated temperatures. The
purge gas temperature must be sufficiently high to
bring the molecular sieve to a level of 250°C - 300°C. A
properly regenerated molecular sieve can produce dew points
below -100°C, mercaptans and CO2 levels <2 ppmv
