Product Details
1)Product introduction
VOCs treatment catalyst is a yellow honeycomb catalyst made of bimetallic platinum(Pt) and copper(Cu) as active components and cordierite honeycomb ceramic as carrier, the size is 100*100*50mm or can be customized according to customer requirements. VOCs treatment catalyst produced by Hunan Xintan is a special process to add a small amount of rare earth materials, so that the catalyst structure is more stable, the surface active coating adhesion is stronger, not easy to fall off. The catalytic performance is excellent, with good temperature resistance, high purification efficiency, and low ignition temperature. The catalyst is suitable for conventional VOCs gas treatment, the treatment effect of benzene series is better, can be widely used in CO and RCO devices. VOCs treatment catalyst is mainly used in waste gas treatment industry, such as spraying, printing, glass fiber reinforced plastic, UV coating, pharmaceutical, chemical, petrochemical, enameled wire and so on.

3)Product advantages
A)Excellent catalytic performance. The purification rate of organic waste gas treated by catalytic combustion method is generally over 95%, and the final products are CO2 and H2O, which are harmless and do not have secondary pollution problems. In addition, due to the lower temperature, NOx generation can be greatly reduced.
B)Wide application range. VOCs treatment catalyst is widely used, mainly used in spraying, printing, glass fiber reinforced plastic, UV coating, pharmaceutical, chemical, petrochemical, enamelled wire and other exhaust gas industry. The composition of the printing industry waste gas is relatively simple, the main components are benzene series, esters, alcohols, ketones and so on.
C)No additional heating required. VOCs treatment catalyst acts as a catalyst at lower temperatures, reducing energy consumption in the catalytic combustion process.
4)Applications
VOCs treatment catalyst is mainly used in waste gas treatment industry, such as spraying, printing, glass fiber reinforced plastic, UV coating, pharmaceutical, chemical, petrochemical, enameled wire and so on.
5) Remark:
A)The catalyst should be moisture-proof, Keep in an airtight container, prevent contact with air, so as not to deteriorate.
B)The waste gas shall not contain sulfur, phosphorus, arsenic, lead, mercury, halogens (fluorine, chlorine, bromine, iodine, astatine), heavy metals, resins, high-boiling point, high-viscosity polymers and other toxic chemical elements or substances.
C)In the process of catalytic combustion reaction, sufficient oxygen should be guaranteed to react with VOCs. When oxygen is insufficient, the purification efficiency of waste gas will be directly affected, resulting in carbon black and other by-products attached to the surface of the catalyst, resulting in catalyst inactivation.
D)The catalyst should be handled gently, and the direction of the catalyst hole should be consistent with the direction of the air flow when filling, and placed closely, without gaps.
E)Before entering VOCs gas, it is necessary to enter flowing fresh air to fully preheat the catalyst (preheat to 240℃~350℃, set according to the highest temperature required by the most difficult gas in the exhaust gas component).
F)The optimal operating temperature of the catalyst is 250~500℃, the exhaust gas concentration is 500~4000mg/m3, and GHSV is 10000~20000h-1. It should be avoided as far as possible to avoid the sudden increase of exhaust gas concentration or the long-term high temperature of catalyst above 600℃.
G)At the end of the operation, firstly cut off the VOCs gas source, use fresh air to continue heating for 20 minutes and then shut down the catalytic combustion equipment. Avoiding catalyst in low temperature contact with VOCs gas, can effectively prolong the service life of catalyst.
H)The dust content of exhaust gas should not be exceed 10mg/m3, otherwise it is easy to cause the blockage of catalyst channel. If it is difficult to reduce the dust to the ideal state before treatment, it is recommended to regularly remove the catalyst and blow it with an air gun before use, without washing it with water or any liquid.
I)When the catalyst is used for a long time, there is a certain decrease in activity, the catalytic bed can be switched before and after or up and down, or the operating temperature of the catalytic chamber can be appropriately increased.
J)When the temperature of the catalytic furnace is higher than 450℃, it is recommended to start the supplementary cooling fan and fill cold air to cool the catalytic furnace to protect the catalyst.
