molecular sieve 13X

molecular sieve 13X: 1. certificate of ISO9001:2008 2. high quality at low price 3. specialized production for 20 years

RP 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. It also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates. It can remove impurities too large to fit into a type A crystal and is commonly used to separate nitrogen from oxygen.

n Sweeten Natural Gas and Liquid Hydrocarbon Streams by Removing H2S and Mercaptans

n Separation of N2 from O2

n PSA Oxygen Units

n Separation of enriched oxygen from air.

n Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.)

n Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).

n Removal of n-chained compositions from aromatics.

n Production of medical oxygen in small scale oxygen concentrators

 

 

REGENERATION

 

RP 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

 

 

HANDLING & STORAGE RECOMMENDATIONS

 

Store RP molecular sieve in a dry location to prevent premature water adsorption. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
