VOC catalyst with Noble metal
1) Product overview
Noble-metal catalyst (100*100*50mm) uses bimetal platinum and copper as the active components and cordierite honeycomb ceramics as the carrier, a small amount of rare earth materials were added through special process to make the catalyst structure more stable, the surface active coating has stronger adhesion and is not easy to fall off. Noble-metal catalyst (HNXT-CAT-V01) has excellent catalytic performance, low ignition temperature, high purification efficiency, and good temperature resistance, suitable for conventional VOCs gas treatment, benzene treatment effect is good, and can be widely used in CO and RCO devices.

3)Remark
- 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.
- 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.
- 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).
- 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.
- 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℃.
- 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.
- 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.
- 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.
- 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.
- The catalyst should be moistureproof, do not soak or rinse with water.
