2. Features and Advantages of Catalysts

2. Wide product range and broad applicability

The full-spectrum VOCs catalysts can be used independently or in combination to treat complex organic waste gas from petrochemical, rubber, organic chemical, pharmaceutical, fine chemical, polymer, coating, printing and petrochemical wastewater treatment industries.

2.1 Excellent selectivity to avoid secondary pollution

(1) Long & short-chain alkane dedicated catalysts feature high catalytic activity and good anti-sintering performance with long service life, reducing secondary pollution and improving process safety.

(2) Chlorine-resistant VOCs catalysts have outstanding anti-poisoning capacity to completely oxidize halogenated organics without polychlorinated by-products or dioxin generation.

(3) Nitrogen-containing VOCs catalysts convert nitrogen elements in nitriles, amines and amides directly into nitrogen gas to prevent NOₓ generation.

2.2 High catalytic activity for easy emission compliance

Adopting exclusive high-activity nano-materials and directional loading technology with synergistic multiple active components and additives, the catalysts feature excellent temperature and poison resistance to thoroughly decompose VOCs and realize steady compliant discharge.

2.3 Stable catalytic performance and long service life

With self-developed durable base materials and proprietary precious metal coating technology, the catalysts boast superior anti-sintering and hydrothermal stability and maintain high catalytic activity for long-term operation.
