Molecular Sieve for VOCs

Our latest product, the molecular Sieve for Volatile Organic Compounds (VOCs), is a molecular sieve designed for the adsorption of volatile organic compound (VOCs). It is hydrophobic as well as organophilic and suitable for the separation and adsorption of VOCs from industry.

About MolecularSieve for VOCs：

Chemical composition and structure

VOC molecular sieves are mainly composed of silicate and aluminate and have an ordered microporous structure. The size and shape of these microholes can be adjusted for specific applications. The skeleton structure of a VOC molecular sieve is composed of silicate and aluminate, which have high chemical and thermal stability.

Adsorption performance

VOC molecular sieves have excellent adsorption properties and can efficiently adsorb and separate volatile organic compounds. 

The adsorption properties of VOC molecular sieves are usually described by adsorption and desorption isotherms. The adsorption and desorption isotherm shows the VOC molecules adsorbed by molecular sieve under different relative pressures. VOC molecular sieve has high adsorption capacity and selective adsorption performance, making it perform excellently in the adsorption process.

Separation performance

VOC molecular sieve has excellent separation performance and can selectively adsorb different VOC molecules according to molecular size and shape differences. This separation performance enables VOC molecular sieves to efficiently recover and separate specific organic compounds, even in complex multi-component mixtures.

Thermal stability and chemical stability

VOC molecular sieves have excellent thermal and chemical stability, which can maintain the stability of their structure and properties under high temperature and high humidity environments. This stability allows VOC molecular sieves to operate reliably in various industrial applications and maintain long-term adsorption properties.

Regeneration performance

VOC molecular sieve has good regeneration performance, which enables it to be regenerated after adsorption saturation. Under certain regeneration conditions, the molecular sieve can recover its adsorption properties and realize recycling. This regenerative performance reduces the cost of replacing the adsorbent and helps to reduce environmental pollution.

Applications of MolecularSieve for VOCs：

Environmental protection field

The VOC molecular sieve is widely used in environmental protection in air and waste gas purification treatment. Due to its excellent adsorption properties and stability, VOC molecular sieve can effectively remove harmful organic compounds in the air, such as benzene, toluene, xylene, etc., as well as harmful gases in the exhaust gas, such as hydrogen sulfide, ammonia, sulfur dioxide, etc. Using a VOCs molecular sieve can significantly improve the quality of air and exhaust gases, protecting the environment and human health.

Chemical industry

VOC molecular sieves are widely used in the chemical industry to separate and purify organic compounds. Because different organic compounds have different molecular sizes and shapes, VOC molecular sieves can achieve selective adsorption of organic compounds through their micropore structure and the role of surface acidic centers. This makes the VOCs molecular sieve an efficient and reliable separation and purification method, improving product quality and yield for chemical production.

The energy sector

VOC molecular sieves are used in fuel and solar cells in the energy sector. By using a VOC molecular sieve, the conversion efficiency and stability of energy can be improved, and the effective use of energy can be achieved. In addition, VOC molecular sieves can also be used in adsorption refrigeration technology to achieve the effect of refrigeration and air conditioning through adsorption.

Biomedical field

In the biomedical field, VOC molecular sieves are also widely used in drug delivery and gene therapy. By wrapping drugs or genes in VOCs molecular sieve, targeted delivery of drugs and practical gene introduction can be achieved. At the same time, VOC molecular sieves can also be used for the separation and purification of biological samples, providing robust technical support for biomedical research.

Production Method of MolecularSieve for VOCs：

Synthesis method

Synthesis is one of the primary methods for preparing VOC molecular sieves. The method uses inorganic compounds as raw materials to synthesize molecular sieve materials by chemical reaction. The specific steps are as follows:

Ingredients: Select the appropriate proportion of inorganic compounds, such as silicates and aluminates, as raw materials.

Synthesis: The raw materials are mixed, adding an appropriate amount of water or organic solvents to form a uniform solution. Then, the hydrothermal reaction is carried out under specific temperature and pressure conditions to polymerize inorganic compounds and generate molecular sieve crystals.

Washing: The generated molecular sieve crystal is washed to remove impurities and unreacted raw materials on the crystal surface.

Drying: The washed molecular sieve crystals are dried to remove the remaining water and solvents.

Activation: The molecular sieve crystal is activated at a specific temperature to enhance its adsorption performance.

The advantages of the synthesis method are that high-quality VOC molecular sieves can be prepared with high adsorption capacity and selectivity. 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 causes environmental pollution.

Activation method

The activation method is relatively simple for preparing VOCs molecular sieve active powder. The method uses a solid surface as raw material to obtain molecular sieve active powder by direct activation treatment. The specific steps are as follows:

Cleaning: The solid surface is cleaned to remove surface impurities and contaminants.

Activation: under specific temperature and pressure conditions, the solid surface is activated to make a chemical reaction occur on the surface to generate molecular sieve active powder.

Collection: The generated molecular sieve active powder is collected for further processing.

The advantages of the activation method are simple operation and low cost. However, the quality of molecular sieve active powder prepared by this method may be low, which needs further treatment and improvement. In addition, the activation method requires using many solid surfaces and water, which causes particular environmental pollution.
