[types and sources of major VOCs]

1. Halogenated volatile organic compounds Halogenated volatile organic compounds have strong bioaccumulation, high toxicity and anti-degradation. Chloromethanes (PCMs) are the most common pollutants, which usually come from chemical extractants, paints, adhesives, pharmaceutical processes, solvents for polymer synthesis reactions and detergents.

2, aldehydes Formaldehyde and acetaldehyde are the most frequently encountered aldehyde VOCs. Aldehydes are one of the most important indoor pollutants, most of which come from the release of decorative materials. Exposure to low-concentration aldehyde air may cause throat irritation and chest tightness. When the concentration is high, it will cause poisoning. Therefore, it is of great significance to oxidize aldehydes at normal temperature.

3. Aromatic compounds Benzene, toluene and ethylbenzene often appear in the production of petroleum products, so the incomplete combustion of liquid fuel will produce a large number of aromatic compounds. Aromatic compounds are not only toxic, but also cause severe damage to ozone, resulting in photochemical smog and mutagenic damage.

4. Polycyclic aromatic hydrocarbons Polycyclic aromatic hydrocarbons are usually composed of multiple benzene rings in structure. Often produced by combustion process. Naphthalene, phenanthrene and pyrene are common. Polycyclic aromatic hydrocarbons (PAHs) are usually carcinogens, and their emissions should be strictly limited.

5. Alcohol and ketone Alcohol and ketone often appear in cosmetics and personal care products, such as nail polish, nail polish remover, cologne and perfume. Ethanol, isopropyl benzyl alcohol, acetone, methacrylate and ethyl acetate are common substances.

6. Others Olefins such as ethylene, propylene and MTBE are also volatile organic compounds.

[Kinetics and Mechanism of Catalytic Oxidation of VOCs]

Due to the different characteristics of pollutants and reaction conditions, it is still difficult to adopt widely used equations and reaction mechanisms. Studies show that the higher the molecular weight, the higher the difficulty of oxidation.

[VOCs oxidation catalyst]

VOCs catalysts can be roughly divided into noble metal catalysts, non-noble metal oxide catalysts and mixed metal catalysts. Metal oxide catalysts are cheap and have strong anti-toxicity. Generally, metal oxides are supported on suitable carriers, and carriers with strong thermal stability and high specific surface area are preferred.
