Description
Molecular Sieve for VOCs Properties
What is Molecular Sieve for VOCs ?
VOC molecular sieve has similar physical properties to activated alumina, including high specific surface area, porosity, and adsorption properties. Its appearance is a white or off-white powder with uniform particle size and smooth surface. The specific surface area of VOC molecular sieves is usually between 300-400m²/g, the pore volume is 0.8-1.6ml/g, and the pore size is between 10-15 anglae. It also has high hygroscopicity, with a hygroscopicity of up to 30%. VOC molecular sieves have good chemical stability and can be used under different temperature and humidity conditions. It is insoluble in water, acid, alkali solutions, and organic solvents and has good chemical inertia. In addition, VOC molecular sieves also have good thermal stability and can be used at high temperatures. VOC molecular sieve's adsorption and separation principle mainly depends on its unique pore structure and surface chemical properties. Its pore size and surface properties can be specifically matched to the target VOC molecule for efficient adsorption and separation. VOC molecular sieves can physically adsorb or chemically adsorb the target VOC molecules, fixing them on the material's surface or in the internal pore to purify air or water. As a new type of environmental protection material, VOC molecular sieve has many advantages. First, it has a high specific surface area and a developed pore structure, which can provide a larger adsorption capacity and a faster adsorption rate. Secondly, it has good chemical and thermal stability and can be used under different environmental conditions. In addition, VOC molecular sieves' regeneration and recycling performance is good, which can reduce the use cost. However, VOC molecular sieves also have some drawbacks. First, its production cost is higher, resulting in a higher market price. Secondly, its hygroscopicity is high, and paying attention to moisture resistance during use is necessary. In addition, different models of VOC molecular sieves target a limited variety of VOCs, and appropriate materials need to be selected to meet the needs of different application scenarios.

Applications of Molecular Sieve for VOCs :
Treatment of industrial waste gas
The industrial production process will release an abundance of aromatic compounds (VOCs), including benzene, xylene, ethane, and ethanol, among others. Organic vapors and gases. These VOCs not only cause harm to the environment and human health but also affect the air quality around the factory. VOC molecular sieves can efficiently adsorb these harmful gases and organic vapors, purify the air, and improve the environmental quality around the plant.
Automobile exhaust treatment
The exhaust from cars is among the primary pollutants that pollute the air in cities, which contains many harmful gases and VOCs, such as benzene, toluene, xylene, etc. Adsorption of these dangerous gases and VOCs on the molecular sieve of VOCs will greatly lessen the damage caused by exhaust fumes from cars to the environment as well as the health of people.
Indoor air purification
The indoor air quality could significantly affect human health, and indoor decoration and furniture will release many VOCs, such as formaldehyde, benzene, and other harmful gases. Using VOCs, molecular sieves can effectively adsorb these harmful gases, purify indoor air, and protect human health.
Catalyst support
VOC molecular sieve is used as a catalyst transporter that is combined with catalysts of specific metals to increase the efficiency and efficiency of catalytic reactions. For example,supported on a VOC molecular sieve can catalyze hydrogenation reactions, oxidation reactions, alkylation reactions, etc.
Water treatment
VOC molecular sieves can be used in water treatment to remove harmful substances and gases from water bodies. For example, organic matter, residual chlorine, and odorous substances can be removed from the water in drinking water treatment. Heavy metal ions and harmful organic matter in sewage treatment can be adsorbed in water.

Productions Method of Molecular Sieve for VOCs :
Raw material preparation: The raw materials required for producing VOC molecular sieves must be prepared. These raw materials usually include organic compounds (such as benzene, toluene, ethane, etc.), inorganic compounds (such as sodium silicate, sodium chloride, sodium sulfate, etc.), and catalysts (such as sulfuric acid, sodium hydroxide, etc.).

Synthesis steps: The prepared raw materials are mixed in proportion, and the reaction is carried out under certain temperature and pressure conditions. This step must usually be carried out in a sealed device to control the reaction process.

Crystal growth: After synthesis, the resulting reaction mixture contains a certain amount of VOC molecular sieve crystals. A crystal growth step is required to obtain larger and more complete crystals. This step usually involves filtering, washing, and drying the reaction mixture to obtain pure molecular sieve crystals.

Molecular sieve synthesis: The obtained molecular sieve crystal is mixed with an appropriate amount of water, and then the synthesis reaction is carried out under certain temperature and pressure conditions. This step usually requires the addition of an appropriate amount of catalyst to facilitate the synthesis of the reaction.

Product separation and washing: The resulting product is separated and washed after the synthesis reaction. This step usually involves filtration, washing, and drying to obtain pure VOCs molecular sieve.

Finished product treatment: Finally, the obtained VOCs molecular sieve for appropriate treatment, such as grinding, packaging, etc., to meet customer needs.
