Problems Caused by Volatile Organic Compounds (VOCs)
Volatile Organic Compounds (VOCs) represent a critical concern across industrial and commercial settings, where these organic chemicals readily evaporate into the air from sources such as solvents, fuels, paints, and manufacturing processes. Without robust management, VOCs compromise indoor air quality and pose significant risks to both human health and the environment.
How to Purify VOC Emissions?
When VOCs have already seriously affected indoor air quality and caused significant harm to human health and the environment, effective treatment and mature solutions are essential. At present, effective catalysts can address and purify the serious adverse consequences caused by VOCs. However, choosing a catalyst with high stability, long service life, and the ability to shorten maintenance intervals—helping operators avoid frequent catalyst replacement and system downtime—is also a critical factor.
Hopcalite Catalyst Powder Produced by DEAI CHEM for VOC Purification
DEAI CHEM independently produces a high-surface-area catalyst that can effectively eliminate ozone and remove trace volatile organic compounds (VOCs) such as formaldehyde from the air stream. This catalyst can be coated onto metal, ceramic, or cellulose substrates. Its applications include, but are not limited to, ozone emissions from printers/copiers, chemical processing emissions, and indoor air treatment to reduce VOCs and odors. It can be used at ambient or low temperatures to facilitate chemical reactions, converting VOCs into safer and more stable byproducts.
Hopcalite Catalyst Powder Specifications
DEAI CHEM’s Hopcalite Catalyst Powder is black/dark brown in color and is manufactured with a MnO₂ and CuO mixture ratio. Its particle size distribution ranges from 3–8 microns, with a BET specific surface area greater than 260 ㎡/g. The high specific surface area enables more effective and rapid chemical reactions, breaking down VOCs into more stable compounds.
Applications of Hopcalite Catalyst Powder in the Industry
1. Direct Application
The catalyst can be directly introduced into the reaction system in its powder form. This approach ensures maximum exposure of active sites, delivering the highest catalytic efficiency and enabling the reaction to proceed at its optimal rate.
2. Shaped Granular Catalyst
Through extrusion, pelletizing, or tablet pressing, the catalyst can be formed into specific shapes (e.g., cylindrical granules or tablets) to facilitate handling, dosing, and integration into fixed-bed reactors or other catalytic systems.
3. Honeycomb Catalyst
Catalyst powder can be uniformly coated onto substrates such as ceramic or aluminum honeycombs. It can also be incorporated into activated carbon honeycombs to produce low-resistance composite catalysts suitable for applications requiring high airflow and minimal pressure drop.
4. Filter-Type Catalyst
The active catalyst can be coated onto substrates such as nonwoven fabric, sponge, alumina, or activated carbon to form a catalytic filter. These are particularly well-suited for use in HVAC systems, ventilation ducts, and air purification devices, offering easy installation and efficient ozone or VOC removal.
