With a uniform pore structure and high chemical stability, they selectively adsorb water molecules efficiently, preventing catalyst poisoning, equipment corrosion, and side reactions in petroleum refining and petrochemical production.

These pellets feature high mechanical strength, low dust generation, and excellent wear resistance, ensuring stable operation under high pressure and temperature conditions. They can be regenerated repeatedly, extending service life and reducing operating costs.

Widely used in cracking, reforming, gas drying and purification in refining systems, they effectively improve product purity and process stability. Compliant with industrial standards, our 3A molecular sieve ensures reliable performance, consistent quality, and strong adaptability for continuous refining operations.

Surface Interactions: Polar molecules (e.g., water, NH3) bind strongly via hydrogen bonding and electrostatic forces. Thermodynamics: Exothermic process;adsorption capacity decreases with temperature. Applications Principles and Functions 1.

Polarity & Adsorption Mechanism Polar Cavity: The aluminosilicate framework creates an electrostatic field within pores due to unsatisfied charges (from Al³+ substitution in SiO4 tetrahedra).

Interactions:Polar Molecules (e.g., H2O, CO2, H2S): Bind via hydrogen bonding or dipole-cation attraction (e.g., H2O → K+ in 3A sieves). Polarizable Molecules (e.g., CO2): Induced dipoles form transient bonds with lattice cations (e.g., Na+ in 13X sieves).

Selectivity: Smaller polar molecules (kinetic diameter ≤ pore size) are preferentially adsorbed over nonpolar ones (e.g., CH4). 2. Role in Desulfurization Target Molecules:H2S (2.6 Å): Strongly adsorbed due to polarity and small size (fits even in 3A sieves).

COS (3.2 Å): Captured by larger-pore sieves (e.g., 4A or 5A). Competitive Adsorption:H2O vs. H2S: Water typically dominates adsorption sites, requiring pre-drying of gas streams to optimize H2S removal.

CO2 Interference: CO2 (3.3 Å) competes with sulfur species in 4A/13X sieves;selective formulations (e.g., metal-doped sieves) mitigate this. Company Profile Pingxiang Rongjian Environmental Protection Chemical Packing Co., Ltd.
