Molecular Sieves 4A

4A molecularsieve is sodium A type silica aluminate. 4A molecular Sieve can absorb molecules of critical diameter less than 4A.

About Molecular Sieves 4A：

Structural characteristics: Molecular sieve 4A has a unique three-dimensional pore structure; its pore size is 4A, so it is named. This structure allows molecular sieve 4A to adsorb efficiently and separate tiny gas molecules.

Adsorption performance: Molecular sieve 4A has high adsorption performance and can adsorb many gas molecules. Its adsorption capacity and rate are higher than other types of molecular sieves. In addition, molecular sieve 4A has a high selectivity and can effectively adsorb and separate specific gas molecules.

Regenerating capacity: molecular sieve 4A can be regenerated by heating, washing, and other recycling methods. This reduces the cost of use and reduces environmental pollution.

Environmental protection: Molecular sieve 4A is an environmentally friendly catalyst that will not produce harmful substances or cause environmental pollution. This makes molecular sieve 4A in environmental protection have many application prospects.

Applicationes of Molecular Sieves, 4A：

Petrochemical field

In the petrochemical field, molecular sieve 4A is mainly used to separate and purify components in petroleum. Because of the unique pore size and selective adsorption properties of molecular sieve 4A, it can effectively separate different hydrocarbon compounds in petroleum, such as alkanes, olefins and aromatic hydrocarbons. In addition, molecular sieve 4A can also be used as a catalyst for petroleum cracking to improve the efficiency and selectivity of the cracking reaction.

The natural gas sector

In the natural gas field, molecular sieve 4A is mainly used for the dehydration, desulfurization and decarbonization of natural gas. Because natural gas contains a lot of impurities such as moisture, hydrogen sulfide and carbon dioxide, these impurities will affect the quality of natural gas and combustion efficiency. Using molecular sieve 4A for adsorption separation, these impurities can be effectively removed, and natural gas quality and calorific value can be improved.

Environmental protection

In environmental protection, molecular sieve 4A is mainly used for waste gas and wastewater treatment. Waste gas contains many harmful gases and particles; using molecular sieve 4A adsorption separation can effectively remove these harmful gases and particles, reducing environmental pollution. In wastewater treatment, molecular sieve 4A can remove pollutants such as heavy metal ions and organic matter and improve wastewater treatment efficiency and water quality.

Medical field

In medicine, molecular sieve 4A is mainly used to separate and purify drugs. Using molecular sieve 4A for adsorption separation, impurities and harmful components in the drug can be effectively removed, and the purity and safety of the drug can be improved. In addition, molecular sieve 4A can also be used as a carrier and sustained-release agent for drugs to improve the efficacy of drugs and reduce side effects.

Food industry

In the food industry, molecular sieve 4A is mainly used to separate and purify food additives. Food additives often contain some harmful impurities and residues; molecular sieve 4A adsorption separation can effectively remove these impurities and residues, improving the safety and quality of food additives. In addition, molecular sieve 4A can also be used for food drying and fresh-keeping treatment.

Electronic industry

In the electronics industry, molecular sieve 4A is mainly used for drying and moisture-proof treatment of electronic components. Electronic components need to be kept dry and moisture-proof during manufacturing and storage to avoid component failure. Using molecular sieve 4A for adsorption treatment, the moisture and moisture in the element can be effectively removed, and the element can be kept dry and stable. In addition, molecular sieve 4A can also be used for heat dissipation and noise reduction of electronic equipment to improve the performance and stability of the equipment.

Production Method of Molecular Sieves, 4A：

Raw material preparation

First, raw materials such as sodium silicate, hydroxide and sulfuric acid must be prepared. Sodium silicate is the primary raw material for preparing molecular sieves, while sodium hydroxide and sulfuric acid are the catalysts in the reaction process. In addition, it is also necessary to prepare a certain amount of template agents, such as organic amines, to control the pore size and specific surface area of the molecular sieve.

Ingredients and mixing

Sodium silicate, sodium hydroxide, sulfuric acid and template agent are mixed proportionally to obtain the mixed liquid. This ratio needs to be determined according to the specific production process.

Aging and aging

The silicic acid gel was aged to make its structure more stable. The time and temperature of aging treatment also need to be determined according to the specific production process.

Washing and drying

The aged silicone gel is washed to remove impurities and unreacted raw materials. After washing, the silicic acid gel is dried to obtain the primary product of the molecular sieve.

Screening and grading

After drying, the primary molecular sieve products were sieved and graded to obtain different particle sizes of molecular sieve products. In this process, the size range of screening and grading needs to be determined according to the application needs of the product.
