How many types of VOCS catalysts are there?

August 01,2023

At present, VOCs catalysts are mainly divided into two categories: noble metal catalysts and non noble metal catalysts.

Precious metal catalysts include platinum, palladium, rhodium, ruthenium, etc. These catalysts have high activity but high cost.

Non noble metal catalysts include oxides, Transition metal oxides, carbon based materials, etc. These catalysts have low cost but low activity.

The performance of VOCs catalysts mainly depends on factors such as the type of catalyst,catalyst surface area, and catalyst pore size. Generally speaking, the larger the surface area of the catalyst, the more suitable the pore size, and the higher the activity of the catalyst. In addition, the stability and lifespan of the catalyst are also important factors to consider.

The application of VOCs catalysts mainly includes the following aspects: waste gas treatment, air purification, organic wastewater treatment, etc.

In waste gas treatment, VOCs catalysts can convert VOCs in the waste gas into carbon dioxide and water, thereby reducing the concentration of VOCs in the waste gas and achieving the goal of purifying the waste gas. In air purification, VOCs catalysts can convert VOCs in indoor air into harmless substances, improving indoor air quality.

When using VOCs catalysts, it is necessary to pay attention to the following points: firstly, the selection of catalysts should be based on the actual situation, including factors such as the type, concentration, and temperature of VOCs in the exhaust gas.

Secondly, the carrier of the catalyst is also important, and suitable carriers should be selected to improve the performance of the catalyst. Once again, the lifespan of the catalyst is also a factor that needs to be considered, and the catalyst needs to be replaced regularly.

Finally, the use of catalysts should comply with relevant national regulations and pay attention to safe operation.

Overall, VOCs catalysts are an important environmentally friendly material with good performance in degrading VOCs. In future environmental protection work, the application prospects of VOCs catalysts are very broad.
