What is a molecular sieve? What is its adsorption principle? What kind of molecular sieve is used for air separation? Read this article to answer your question.
Molecular sieve is a silica-aluminate, which is mainly composed of silica and alumina through the oxygen bridge, forming an open framework structure. In this structure, there are many holes with uniform diameter and well-arranged holes, which have large internal surface area and. In addition, it also contains low electricity price and large ion radius of metal ions and combined state of water. Due to the continuous loss of water molecules after heating, but the crystal framework structure remains unchanged, many cavities of the same size are formed, and the cavities are connected by multiple micropores with the same diameter, and the molecules of the material have the same diameter.
Pores smaller than the diameter of the pore are adsorbed in the cavity. Molecules larger than the pores are repelled, so molecules of different sizes are separated until the action of the sieve molecules is called a molecular sieve.
It is mainly used in various gas deep drying, liquid, separation and purification of gas, liquid, catalyst carrier, etc., so it is widely used in refining, petrochemical, chemical industry, metallurgy, electronics, national defense industry, and in medical, optical work, agriculture, environmental protection and many other aspects are also more and more widely used.
What is the application of 13X APG molecular sieve?
Mainly used for large and medium-sized air separation plant material purification (together with the removal of H2O and CO2) and part of the hydrocarbon, natural gas, liquefied petroleum gas, liquid hydrocarbon boring and desulfurization; Common gases are boring.
Molecular Sieve Regeneration
Moisture removal: it depends on the pressure, temperature and water content of the gas. In general, 200 ~ 350 ℃ dry gas under pressure from 0.3 ~ 0.5 Kg/cm2, through molecular sieve bed 3 ~ 4 hours, the outlet temperature to 110 ~ 180 ℃, the cooling.
De-organic: replace organic matter with water vapor and then remove water.
Storage: room temperature, relative humidity is not more than 90% of indoor: prevent water, acid, alkali, barrier air, sealed preservation.
Packing: 25KG or 30KG cartons with vacuum bags inside,, 135Kg sealed steel drum.
