VOCs treatment catalyst (Pt and Pd )
The VOCs treatment catalyst has two core active components, platinum (Pt) and copper (Cu), and its carrier is cordierite honeycomb ceramic. This unique combination gives the catalyst a yellow honeycomb like appearance. In terms of size, we offer standard sizes of 100/100/50mm and can also customize according to specific customer needs.
Of particular note, the VOCs treatment catalyst produced by Hunan Xintan cleverly incorporates rare earth materials during the preparation process. This innovative process not only significantly enhances the structural stability of the catalyst, but also greatly improves the adhesion of the surface active coating, ensuring that it is not easily peeled off during long-term use.
In terms of performance, this catalyst exhibits excellent catalytic activity, excellent high-temperature resistance, and efficient purification ability. What’s even more impressive is that its ignition temperature is extremely low, which means it can be started and put into the treatment of VOCs gas faster in practical applications.
In addition, this catalyst exhibits excellent performance in the treatment of conventional VOCs gases, especially in the treatment of benzene derivatives. Therefore, it is widely used in CO and RCO devices and has become an ideal choice for waste gas treatment industries such as spraying, printing, fiberglass, ultraviolet coatings, pharmaceuticals, chemicals, petrochemicals, enameled wires, etc.

product details
1) Product Introduction
VOCs treatment catalyst is a yellow honeycomb shaped catalyst made of bimetallic platinum (Pt) and copper (Cu) as active components, and cordierite honeycomb ceramics as carriers. Its standard size is 10010050mm, but it can also be customized according to specific customer needs. The VOCs treatment catalyst produced by Hunan Xintan adopts a special process of adding a small amount of rare earth materials, which makes the structure of the catalyst more stable, enhances the adhesion of the surface active coating, and is not easy to peel off. This catalyst has excellent catalytic performance, good heat resistance, high purification efficiency, and lower ignition temperature. It is suitable for the treatment of conventional VOCs gases and has a particularly good treatment effect on benzene series, so it can be widely used in CO and RCO devices. VOCs treatment catalysts are mainly used in the waste gas treatment industry, such as spraying, printing, fiberglass, ultraviolet coatings, pharmaceuticals, chemicals, petrochemicals, enameled wires, and other fields.

3) Product advantages
A) Excellent catalytic performance: The purification rate of organic waste gas treated by catalytic combustion method generally exceeds 95%, and the final products are harmless CO2 and H2O, which will not cause secondary pollution problems. In addition, due to the lower temperature, the generation of NOx can be greatly reduced.
B) Wide range of applications: VOCs treatment catalysts are widely used, mainly in industries such as spray painting, printing, fiberglass, ultraviolet coatings, pharmaceuticals, chemicals, petrochemicals, enameled wires, and other waste gas treatment. The composition of exhaust gases in the printing industry is relatively simple, mainly including benzene series, esters, alcohols, ketones, etc.
C) No additional heating required: VOCs treated catalysts can exert catalytic effects at lower temperatures, reducing energy consumption during catalytic combustion.
4) Application field
VOCs treatment catalysts are mainly used in the waste gas treatment industry, such as spraying, printing, fiberglass, ultraviolet coatings, pharmaceuticals, chemicals, petrochemicals, enameled wires, and other fields.
5) Precautions
A) Storage of catalysts: Catalysts should be moisture-proof and stored in sealed containers to avoid contact with air and prevent spoilage.
B) Limitations on exhaust gas composition: The treated exhaust gas should not contain toxic chemical elements or substances such as sulfur, phosphorus, arsenic, lead, mercury, halogens (fluorine, chlorine, bromine, iodine, astatine), heavy metals, resins, high boiling point, high viscosity polymers, etc.
C) Ensure sufficient oxygen: During catalytic combustion reactions, it should be ensured that there is sufficient oxygen to react with VOCs. Insufficient oxygen can directly affect the purification efficiency of exhaust gas, which may lead to the deposition of by-products such as carbon black on the catalyst surface, resulting in catalyst deactivation.
D) Catalyst filling and placement: The catalyst should be handled with care, and the direction of the catalyst holes should be consistent with the direction of the airflow during filling, and placed tightly without leaving any gaps.
E) Catalyst preheating: Before VOCs gas enters, flowing fresh air should be introduced to fully preheat the catalyst (preheating to 240 ℃~350 ℃, set according to the highest temperature required for the most difficult to treat gas in the exhaust gas composition).
F) The optimal operating conditions of the catalyst: the optimal operating temperature of the catalyst is 250-500 ℃, the exhaust gas concentration is 500-4000mg/m3, and the GHSV is 10000-20000h-1. Efforts should be made to avoid sudden increases in exhaust gas concentration or prolonged catalyst temperatures exceeding 600 ℃.
G) Shutdown operation: When shutting down, the VOCs gas source should be cut off first, and fresh air should be used to continue heating for 20 minutes before shutting down the catalytic combustion equipment. Avoiding contact between the catalyst and VOCs gas at low temperatures can effectively extend the service life of the catalyst.
H) Limit on dust content in exhaust gas: The dust content in exhaust gas should not exceed 10mg/m3, otherwise it may cause blockage of catalyst channels. If it is difficult to reduce the dust to the ideal state before processing, it is recommended to regularly remove the catalyst and blow it with an air gun to avoid cleaning with water or any liquid.
I) Catalyst activity maintenance: After long-term use, the catalyst activity may decrease. At this time, the catalytic bed can be switched back and forth or up and down, or the operating temperature of the catalytic chamber can be appropriately increased.
J) High temperature protection measures: When the temperature of the catalytic furnace exceeds 450 ℃, it is recommended to start the auxiliary cooling fan and introduce cold air to cool the catalytic furnace to protect the catalyst.
