Molecular Sieves 13X Column
Super Packing Mall Molecular Sieve 13X Column
Molecular sieve 13X Column is the one with the largest pore size in the molecular sieve series. The pore size of 13X molecular sieve is 10A, which can adsorb molecules with a molecular diameter of less than 10A. It is usually used in various gas separations, such as moisture separation in adsorption dryers. 13X molecular sieves are usually used It is used to absorb water, CO2, H2S and other gases in petroleum cracking gas, natural gas and other gases to purify the gas.In addition to drying and purifying gases, 13X molecular sieves can also be used in pressure swing adsorption systems. For example, molecular sieves can be used in industrial PSA oxygen production processes to purify oxygen in the air
Pressure swing adsorption (PSA) and temperature swing adsorption (TSA) are some of the potential techniques that could be applicable for removal of CO2 from high-pressure fuel gas streams. Molecular sieves and activated carbons are some of the sorbents that could be utilized in the PSA process. Volumetric adsorption studies of CO2, N2, or H2 on molecular sieve 13X, molecular sieve 4A, and activated carbon were conducted at 25 °C up to a pressure of 300 psi (∼2× 106 Pa). Preferential adsorption of CO2 was observed with all three sorbents. The adsorption capacity of CO2 for molecular sieve 13X was higher than that for molecular sieve 4A at all pressures up to 300 psi. At low pressures (<25 psi) the adsorption capacity for CO2 of activated carbon was lower than that of molecular sieve 13X, but at higher pressures (>25 psi) activated carbon exhibited significantly higher CO2 capacities than were found for molecular sieves. Competitive adsorption of CO2 from gas mixtures also indicated that both molecular sieve 13X and activated carbon can be utilized for separation of CO2 from gas mixtures.
Application
a) Removal of CO2 and moisture from air (air pre-purification) and other gases.
b) Separation of enriched oxygen from air.
c) Removal of n-chained compositions from aromatics.
d) Removal of R-SH and H2S from hydrocarbon liquid streams (LPG, butane etc.)
e) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
f) Production of bulk oxygen in PSA units.
Molecular sieve of Super Packing Mall has uniform particles, balanced quality, high strength, and is not easy to be crushed. It is suitable for various adsorption drying devices
13X molecular sieve can quickly absorb impurities in the gas, and at the same time, it can also play a role in removing odors
