"VOCs removal catalyst" or "Volatile Organic Compounds (VOCs) removal catalyst." This refers to a catalyst used to facilitate the chemical reaction that removes volatile organic compounds from air or industrial emissions, aiming to reduce air pollution and improve environmental quality.

Common Types of Catalysts:

VOCs catalysts mainly include precious metal catalysts and non-precious metal catalysts.

Precious Metal Catalysts: These include precious metals such as platinum and palladium. They have high catalytic activity, thermal stability, and resistance to poisoning. However, their cost is relatively high.

Non-Precious Metal Catalysts: Examples include cobalt-manganese oxides and copper-manganese oxides. Compared to precious metal catalysts, non-precious metal catalysts have a lower cost but exhibit relatively weaker catalytic activity and resistance to poisoning.

Ozone is a strong oxidizing agent with an oxidation-reduction potential of 2.07 V in water, second only to fluorine. Its oxidizing ability is higher than that of chlorine and chlorine dioxide. Ozone can destroy bacterial cell walls, quickly diffuse into cells, and directly interact with bacteria and viruses. It disrupts large molecular polymers such as cells, proteins, lipids, and polysaccharides, thereby impairing the metabolism and reproduction of bacteria. Excessively high concentrations of ozone can have significant impacts on both the environment and human health.

The working principle of ozone decomposition catalysts is based on redox reactions. These catalysts are typically prepared by forming one or more metal oxides. They effectively adsorb and catalyze the decomposition of ozone, rapidly breaking down excess ozone after aeration without consuming any additional energy. The catalysts are characterized by high decomposition efficiency and long service life.

Active aluminum oxide is a white, spherical, porous material with uniform particle size, a smooth surface, and high mechanical strength. It has strong dilutability, does not swell or crack upon water absorption, and maintains its original shape. It is non-toxic, odorless, insoluble in water and ethanol, and can be regenerated. Active aluminum oxide features adsorption properties and catalytic activity, and is characterized by its high porosity, high dispersion, and large specific surface area.

Inert alumina balls, also known as industrial ceramic balls or packing ceramic balls, are ceramic spheres with excellent chemical and thermal stability. They are primarily made from industrial alumina and kaolin, shaped and fired at high temperatures, resulting in a uniform appearance and outstanding physical properties. Inert alumina balls can resist corrosion from acids, alkalis, and other organic solvents, and can also withstand temperature fluctuations that may occur during production. These characteristics make inert alumina balls widely used in industries such as petroleum, chemicals, fertilizers, natural gas, and environmental protection, particularly as covering and support materials for catalysts within reactors and as tower packing.

3A molecular sieve is an alkali metal aluminosilicate with a pore size of 3 angstroms (0.3 nanometers), created by potassium ion exchange in an A-type molecular sieve. Due to its internal structure containing numerous 3-angstrom crystal adsorption cavities, it can adsorb molecules with a diameter smaller than 3 angstroms while not adsorbing any molecules with a diameter greater than 3 angstroms. It has a strong selective adsorption for water molecules, making it commonly used as a selective adsorbent and drying agent for various gases and liquids.

4A molecular sieve is an alkali metal aluminosilicate with a pore size of 4 angstroms (0.4 nanometers), and it is a sodium-containing A-type molecular sieve. Due to its internal structure containing numerous 4-angstrom crystal adsorption cavities, it can adsorb molecules with a diameter smaller than 4 angstroms while not adsorbing any molecules with a diameter greater than 4 angstroms (including propane). It has a strong selective adsorption for water molecules, making it commonly used as a selective adsorbent and drying agent for various gases and liquids.

5A molecular sieve is an alkali metal aluminosilicate with a pore size of 5 angstroms (0.5 nanometers), made from calcium ion exchange in an A-type molecular sieve. Due to its internal structure containing numerous 5-angstrom crystal adsorption cavities, it can adsorb molecules with a diameter smaller than 5 angstroms while not adsorbing any molecules with a diameter greater than 5 angstroms. It is primarily used for the separation of normal paraffins, pressure swing adsorption separation, and the co-adsorption of water and carbon dioxide.

13X molecular sieve is an alkali metal aluminosilicate with a pore size of 10 angstroms (1 nanometer), and it is a sodium ion X-type molecular sieve. Due to its internal structure containing numerous 10-angstrom crystal adsorption cavities, it can adsorb molecules with a diameter smaller than 10 angstroms while not adsorbing any molecules with a diameter greater than 10 angstroms. It can be used as a catalyst support, for co-adsorption of water and carbon dioxide, and for co-adsorption of water and hydrogen sulfide gases. It is mainly applied in the drying of pharmaceuticals and air compression systems, offering higher adsorption capacity and lower dew points.

Micro-electrolysis catalytic reactors are widely used for the pre-treatment and deep treatment of high-concentration, hard-to-degrade organic wastewater. The series of micro-electrolysis catalytic reactors produced by Longantai Company are essential for ensuring the continuous operation of the micro-electrolysis primary cell reactions.

The ozone catalytic oxidation reactor mainly consists of the reactor's main shell, proprietary internal tower components, and proprietary ozone catalytic filler.

The proprietary internal tower components achieve efficient mixing of ozone gas and wastewater, combined with our patented series of ozone catalysts, which enhances the utilization of ozone.

The ozone high-efficiency gas dissolver can rapidly and efficiently dissolve ozone into water, thereby increasing the reaction speed and efficiency of ozone in the water treatment process, and further enhancing the purification effect of the water.

The ozone gas destruction device is a skid-mounted equipment used for the rapid decomposition of ozone gas. It employs a heating catalytic type and utilizes self-developed decomposition catalysts. The ozone concentration at the device's outlet is less than 0.1 ppm.
