Molecular Sieves Based on 3A, 4A, 5A and 13X Zeolites
Application:
* Zeolite 3A: sodium-potassium aluminosilicate with a pore diameter of 3 angstroms, used in the deep drying (dehydration) of fuel gases from the cracking process, unsaturated hydrocarbons (ethylene, propylene, butadiene and acetylene), aromatic compounds (BTX), light alcohol solvents (ethanol and methanol) and food grade CO2 gas.
* Zeolite 4A: sodium aluminosilicate with a pore diameter of 4 angstroms, used in drying gases, natural gas, alkane solvents, gases such as argon, drying agent for pharmaceutical packaging and electronic components.
* Zeolite 5A: calcium-sodium aluminosilicate with a pore diameter of 5 angstroms, used for drying natural gas and absorbing CO2, CO and H2S, nitrogen, hydrogen and inert gases.
* Zeolite 13X: X-type sodium aluminosilicate with 9 angstrom pore diameter, used for absorption of water, mercaptans and CO2, typical industrial air drying, low recovery temperature and long service life.
Product Introduction:
Zeolites are a type of molecular sieves, which, due to the high polarity of the internal surfaces of their cavities, are among the most important selective surface (physical) absorbers of water and sulfur compounds of oil and gas (such as mercaptans and H2S), which is essential in the crude oil and gas refining process. In addition, they absorb impurities and pollutants from water streams (essential in wastewater treatment) as well as air pollutants such as CO and CO2 well. These compounds are a type of aluminosilicate, which have different types based on their molecular structure and crystal network, and they can be divided into two types of natural and synthetic zeolites. Among the most important synthetic zeolites, we can mention zeolites A, X, Y and ZSM-5. The reason for naming three types of zeolite A, namely 3A, 4A, and 5A, is because of their pore sizes, which are Å3, Å4, and Å5, respectively. The size of the hole is the main factor in the speed of absorption, the strength of absorption and also the type of material that can be absorbed. These three types of zeolite can be converted into each other through the ion exchange process in an environment saturated with the corresponding metal salt.
Technical Specifications:
Synthetic zeolites consist of three main bases: zeolite powder, binders and other additives needed to improve properties. In general, the production process of these products includes the process of preparing the raw materials, mixing the components (in the right proportion and based on the formulation according to the specific application) and proper shaping. Based on the need, this shaping can be spherical (bead) (through the pen granulator or bead former) or string (through the extruder). Next, in order to remove the physical water in the macropores, drying is done. Finally, in order to remove the chemical water present in the meso and micro pores and increase the thermal, mechanical and chemical stability, calcination and activation operations are performed. Various BET, XRD, XRF, ICP, Atomic Absorption and Particle Size, Strength (Crush) and Attrition analyzes have been conducted by the company.

Application:
Among the applications of these compounds are the removal of oil and gas sulfur compounds such as mercaptans and H2S (which is essential in the process of refining crude oil and gas) as well as air pollutants such as CO and CO2. Another important application of these zeolites is the use in washing powders as an agent for absorbing calcium ions from water.
Application:
Zeolite Y is the main catalyst component used in FCC/RFCC refinery units. The selectivity and catalytic activity of these types of catalysts are due to zeolite Y. Although this zeolite has other applications such as dehumidification, its mainly used in the world as the main catalyst component of the FCC/RFCC residue fluid catalytic cracking process.
