Molecular sieve 3A is an alkali metal aluminosilicate with a pore size of 3 angstroms. It is a type A crystal structure，mainly used to adsorb water and does not adsorb any molecules with a diameter greater than 3 angstroms. Xintao 3A molecular sieve desiccant has the characteristics of fast adsorption speed and high compressive strength. It is the preferred desiccant for deep drying, refining and polymerization of gas and liquid in the petroleum and chemical industries.
The pore size of molecular sieve 4A is 4 angstroms, and it is a sodium type of A-type crystal structure. It can adsorb any molecule with a critical value not greater than 4A, such as water, methanol, ethanol, ethylene, propylene, hydrogen sulfide, sulfur dioxide, carbon dioxide, ammonia, etc. Xintao 4A molecular sieve beads have very good adsorption performance and good oil adhesion, which is safe and reliable for human body and has no adverse effect on ecology.
Molecular sieve 5A has a caliber of 5 angstroms and is a calcium type of A-type crystal structure. It can adsorb any molecule with a diameter less than 5 angstroms. In addition to the functions of 3A and 4A zeolite molecular sieves, it can also adsorb normal alkanes, ethyl chloride, ethyl bromide, butanol, etc. Xintao 5A zeolite desiccant has high selective adsorption and is particularly suitable for pressure swing adsorption.
The pore size of molecular sieve 13X is 10 angstroms. It is a sodium type with an X-type crystal structure and can adsorb any molecule with a diameter less than 10A. Xintao 13X molecular sieve zeolite can be used for co-adsorption of H2O and CO2, co-adsorption of H2O and H2S, and drying of pharmaceutical and air compression systems.
The main component is aluminosilicate, and the pore size is 10 angstroms. Xintao molecular sieve 13X APG zeolite has a high CO2 adsorption capacity, and can also adsorb trace moisture, acetylene and other hydrocarbons in the air. It is suitable for various sizes of deep-cold air separation devices to produce O2, and its O2 production concentration is as high as 99%.
Molecular sieve 13X HP is a special molecular sieve for oxygen production. It has a pore size of 10 angstroms, a high nitrogen adsorption capacity, an excellent nitrogen-oxygen separation coefficient, a higher oxygen purity and a faster adsorption speed. Its oxygen concentration is 93%~96%, making it a good companion for oxygen production systems.
Lithium molecular sieve Bead is used for air separation to produce oxygen and oxygen-enriched air. It has better adsorption capacity and separation efficiency and is suitable for small vacuum pressure swing adsorption devices. The concentration of oxygen produced reaches 96%. It has a higher nitrogen-oxygen separation coefficient at extremely low adsorption pressure, thereby reducing oxygen production energy consumption and improving efficiency.
The main component of carbon molecular sieve is elemental carbon, and its appearance is black columnar solid. It contains a large number of micropores with uniform pore size. The micropores have a strong instantaneous affinity for oxygen molecules. It is used to separate O2 and N2 in the air and is suitable for various types of pressure swing adsorption nitrogen generators.
Xintao molecular sieve powder is a 2~4 micron white powder with good dispersibility, fast adsorption speed and strong activity. As an amorphous desiccant, it mainly reduces moisture, eliminates bubbles, and improves material uniformity and strength.

Xintao has many export and customer service cases, you can learn about them here.
Xintao carbon molecular sieves are widely used in nitrogen production equipment in industries such as petroleum, chemical, coal mining, metallurgy, tires, medical, food, aviation, etc.
As a refinery, the customer needs to use molecular sieves to absorb water during the production process of cracking to produce ethylene.
Xintao sent out 3A molecular sieves that meet professional standards within one week, and arranged a professional technical team to the customer’s site for filling services.
The customer ordered 36 tons of oxygen molecular sieves and 6 tons of activated alumina, and our technical team went to Hunan for on-site installation guidance.
3A, 4A, 5A, and 13X molecular sieves have different effective pore sizes, which are 0.3nm, 0.4nm, 0.5nm, and 1nm respectively, and their application scenarios are also different. 3A is used for ethanol drying, 4A is used for deep gas dehydration and drying, 5A is used for oil and natural gas drying, and 13X is used for adsorption of impurities in air separation and purification devices.
Molecular sieve selectively adsorbs based on molecular size and polarity. The interior of its crystal pores has strong polarity and Coulomb field, and has strong adsorption capacity for polar molecules and unsaturated molecules. Only substances with molecular diameters smaller than the pore diameter can enter the crystal pores.
- Polar adsorption: The surface of the molecular sieve has a certain polarity. For polar molecules or polarizable molecules, they can have a strong effect on the surface of the molecular sieve, or induce the polarization of the molecules to produce strong adsorption, while non-polar molecules are not easily adsorbed.
Common regeneration methods include heating regeneration and decompression regeneration. Heating can desorb the adsorbed substances, and decompression can reduce the partial pressure of the adsorbate on the surface of the molecular sieve to promote desorption. However, regeneration requires good control of temperature, pressure and other conditions to ensure that the performance of the molecular sieve is not damaged.
The service life is limited and varies depending on factors such as the use environment and regeneration conditions. Generally, it needs to be replaced regularly to ensure performance. Its filtration efficiency will decrease over time and needs to be replaced frequently, which may affect production operations and increase maintenance costs. Xintao molecular sieves can be used for 3 to 5 years under normal use and maintenance conditions, but the specific use environment, frequency and regeneration conditions vary.
They are widely used in petrochemical, natural gas drying, air separation, refrigeration, medicine, food and other industries. They can be used for drying, purification and separation of gases and liquids.
They are mainly affected by factors such as temperature, pressure, humidity, gas flow rate, and the properties of the adsorbed substance. Generally speaking, low temperature, high pressure, low humidity, and low gas flow rate are conducive to improving adsorption performance.
The molecular sieve in the oxygen concentrator can selectively adsorb nitrogen according to the size and diffusion rate difference between nitrogen molecules and oxygen molecules, thereby achieving the separation of oxygen and nitrogen and obtaining high-concentration oxygen.
Xintao molecular sieve zeolite have uniform pore size, high selectivity, strong adsorption performance, good thermal stability and chemical stability, and perform well in separation and purification processes with high precision requirements.
They are relatively safe in themselves, but during use and handling, care should be taken to avoid inhaling dust and preventing irritation to the respiratory tract. In some specific applications, such as the food and pharmaceutical industries, their compatibility and safety with the product must also be considered.
Xintao is usually more secure in terms of quality control, technical support and after-sales service. Good after-sales service can promptly solve problems in use, provide technical consultation and maintenance suggestions, and make customers feel more assured when using it.
