Dioxide Removal 4.8mm 4*8 Mesh 13x Desiccant

Product introduction

Molecular sieve also called zeolite, is a crystalline aluminum silicate. Its crystal structure has neat and uniform channel, aperture around a molecular level, molecular sieve only allows smaller diameter than its aperture into it, so it can sieve molecules according to their size in the mixture, so it called molecular sieve. According to molecular sieve aperture size, there are 3A, 4A, 5A, 10X, 13X. 4A molecular sieve is Na-A molecular sieve, aperture 0.4nm; if Na replaced by K, aperture 0.3nm, is 3A molecular sieve; if over 1/3 Na replaced by Ca2+, aperture 0.5nm, is 5A molecular sieve.

13X molecular sieve, also called Natrium X molecular sieve, Zeolite 13X, is a kind of alkali metal silicon aluminate, its skeleton structure composed of silica and alumina tetrahedral FAU, main crystal holes are twelvering structures. To the X type molecular sieve,if silicon aluminum ratio is not the same, crystal structures are different. 13X molecular sieve silicon aluminum ratio≈2.6-3.0 (SiO2/Al2O3≈2.6-3.0), aperture 10A, it can adsorb any molecules which critical diameteris greater than 3.64A and less than 10A, as long as the molecules can be adsorbed by 3A, 4A, 5A type molecular sieve, they also can be adsorbed by 13X molecular sieve. Furthermore, 13X molecular sieve can adsorb bigger critical diameter molecules, such as aromatic hydrocarbons and branched chain hydrocarbons.

Scope of application

The gas purification in the air separation unit removes water and carbon dioxide.

Drying and desulfurization of natural gas, liquefied petroleum gas, and liquid hydrocarbons.

Generally, the gas is deeply dry.

13X molecular sieve technical Index:

Store

Room temperature, relative humidity not greater than 90% indoors: avoid water, acid, alkali, isolate air, and store in airtight.

Regeneration

Removal of water: dry gas such as nitrogen, air, hydrogen, saturated hydrocarbon, etc. can be heated to 150-320°C and pass into the molecular sieve bed under 0.3-0.5kg/m2 pressure for 3-4 hours, and then to the adsorber Pass in dry cold air for about 2-3 hours, isolate the air and cool to room temperature.

Removal of organic matter: the adsorbate can be replaced from the molecular sieve with water vapor, and then heated to (1). The regeneration can also be regenerated by superheated steam or inert gas at 200-350℃. Exposure to gases that produce explosive mixtures).

The degassed substances can be regenerated by the decompression removal method.

Package

Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.
