About Molecular sieve activated powder:

Structure of molecular sieve active powder

Molecular sieve active powder is an inorganic compound with a regular and ordered micropore structure. Its micropore size is usually in the nanometer scale, which can effectively adsorb and separate molecules. The structure of such materials usually presents a three-dimensional skeleton structure, which contains a large number of tetrahedral structural units. These tetrahedral structural units form holes by sharing oxygen atoms, and these holes have high geometric symmetry, which can achieve selective adsorption and separation of molecules of different sizes and shapes.

The adsorption performance of molecular sieve active powder

Molecular sieve active powder has excellent adsorption properties and can effectively adsorb molecules in gases and liquids. Its adsorption properties mainly depend on its many pores and surface acidic centers. These acidic centers can interact with adsorbent molecules to achieve efficient adsorption. The adsorption performance of molecular sieve active powder is manifested in conventional and liquid adsorption and in some particular adsorption fields, such as the removal of harmful substances in waste gas recovery of organic matter in industrial wastewater.

Ion exchange performance of molecular sieve active powder

The zeolite active powder also has excellent ion exchange properties and can be reversibly exchanged with cations or anions in solution. This ion exchange property is due to the large number of exchangeable cations or anions on its surface. These exchangeable ions can be exchanged with corresponding ions to achieve adsorption and separation. The ion exchange properties of molecular sieve active powder have been widely used in wastewater treatment and recovery of valuable metal ions.

The stability of molecular sieve active powder

Molecular sieve active powder has high thermal and chemical stability and can maintain the stability of its structure and properties under high temperature and high-pressure conditions. In addition, it also has good acid resistance, alkali resistance and hydrolysis resistance, which can maintain the stability of its performance under various environmental conditions. This stability makes molecular sieve active powder perform excellently in various application fields.

Regeneration performance of molecular sieve active powder

Molecular sieve active powder also has good regeneration performance. After the adsorption or ion exchange process ends, it can be restored to the original state by a particular method to carry out the following adsorption or ion exchange operation. This regenerative performance can effectively reduce operating costs and improve work efficiency.

Selectivity of molecular sieve active powder

Molecular sieve active powder has good selectivity and can achieve selective adsorption and separation of molecules of different sizes and shapes. This selectivity is due to its regular and ordered microporous structure and surface acidic center. This selectivity makes molecular sieve active powder and performs excellently in many applications, such as gas separation, liquid separation, ion exchange, etc.

Applications of Molecular Sieve activated powder:

Catalyst field

Molecular sieve active powder has been widely used in the field of catalysts. Because of its regular and ordered microporous structure and surface acid center can be used as a catalyst carrier to provide excellent catalytic performance. For example, in the petrochemical industry, molecular sieve active powder can prepare highly active catalysts for petroleum cracking, reforming, and other reactions to improve the quality and yield of petroleum products. In addition, in environmental protection, molecular sieve active powder can also be used to prepare catalysts for treating waste gas and wastewater to remove harmful substances and achieve environmental protection and energy savings.

The field of adsorbents

Molecular sieve active powder is also widely used in the field of adsorbents. Due to its excellent adsorption properties and selectivity, it can separate and purify molecules in gases and liquids. For example, in air separation, molecular sieve active powder can be used for efficient adsorption and separation of oxygen and nitrogen to achieve oxygen and nitrogen separation. In addition, for environmental protection, molecular sieve active powder can be used to adsorb and recover harmful substances in wastewater and purify water and air quality. At the same time, in food and medicine, molecular sieve active powder can also be used to separate and purify organic compounds and pharmaceutical ingredients.

Ion exchanger field

Molecular sieve active powders are also widely used in the field of ion exchangers. Because of its excellent ion exchange performance and stability can be used to recover valuable metal ions and wastewater treatment. For example, in metal extraction, molecular sieve active powder can be used to adsorb and separate metal ions in solution to achieve the enrichment and recovery of metal ions. In addition, in wastewater treatment, molecular sieve active powder can be used to adsorb and remove harmful substances in wastewater to achieve purification treatment of wastewater.

Production Method of Molecular Sieve activated powder:

Synthesis method

Synthesis is one of the leading production methods of molecular sieve active powder. The method uses inorganic compounds as raw materials to synthesize molecular sieve active powder through a chemical reaction. The specific steps are as follows:

The inorganic compound is mixed according to a particular proportion, and the appropriate amount of water or organic solvent is added to form a uniform solution.

The solution was subjected to hydrothermal reaction at a specific temperature and pressure, and the inorganic compounds were polymerized, and molecular sieve crystals were formed.

The generated molecular sieve crystals were washed and dried to obtain molecular sieve active powder.

The advantages of the synthesis method are the high purity and stable performance of molecular sieve active powder. However, the reaction conditions of this method are relatively harsh, requiring high temperature and high-pressure conditions, so the production cost is high. In addition, the synthesis method needs to use a lot of inorganic compounds and water, which inevitably pollutes the environment.

Ion exchange method

The ion exchange method is a method to obtain molecular sieve active powder by reversibly exchanging ion exchangers with ions in solution. The raw materials used in this method are ion exchangers, such as zeolite, activated carbon, etc. The specific steps are as follows:

The solution is ion-exchanged with the solution containing the target ion, and the target ion is adsorbed on the ion exchanger.

The ion exchanger adsorbed with target ions was washed and dried to obtain molecular sieve active powder.

However, the purity and performance of this method's molecular sieve active powder may be low, which needs further treatment and improvement. In addition, the ion exchange method requires using many ion exchangers and water, which causes environmental pollution.

Direct activation method

The direct activation method is a method to obtain molecular sieve active powder by direct activation of a solid surface. The raw material used in this method is a solid surface, such as silica gel, activated carbon, etc. The specific steps are as follows:

The solid surface is pre-treated, such as cleaning, drying, etc.

The pre-treated solid surface is activated under specific temperature and pressure conditions to make the surface react chemically.

The activated solid surface was washed and dried to obtain molecular sieve active powder.

The advantages of direct activation are simple operation and low cost. However, the purity and performance of this method's molecular sieve active powder may be low, which needs further treatment and improvement. In addition, the direct activation method requires using a large amount of solid surface and water, which causes particular environmental pollution.

In actual production, different production methods can be selected according to different needs and raw materials. Synthesis and ion exchange methods are more suitable for large-scale, high-quality production. For small-scale, low-cost production, the direct activation method is more suitable. With the development of science and technology and the expansion of application fields, the production method of molecular sieve active powder will be continuously improved and perfected.
