High efficiency and environmental protection! Uncovering the five core applications of ozone decomposition catalysts in the chemical industry

In recent years, with the increasingly stringent environmental regulations, ozone decomposition catalysts, as a key technology for the green transformation of the chemical industry, have attracted much attention for their application value. This article will explore in depth the core application scenarios and technical advantages of this technology in chemical production.

一、The "green heart" of industrial waste gas treatment

Ozone decomposition catalysts catalyze the chain reaction of decomposing ozone (O₃) into oxygen (O₂), showing excellent performance in chemical waste gas treatment:
Reaction efficiency: Under 200-300℃ working conditions, the ozone conversion rate can reach more than 99.8%
Economic performance: 40% lower operating costs than traditional activated carbon adsorption method
Typical case: After a petrochemical company adopted Mn-Ce-based catalysts, the VOCs emission concentration dropped from 120mg/m³ to 15mg/m³

二、Key technologies of ozone tail gas purification system

In the application scenarios of ozone generators such as chlor-alkali industry and electronic cleaning:
Honeycomb ceramic carrier catalysts achieve a gas processing capacity of 100,000 m³/h
Anti- Wet performance: maintain more than 95% decomposition efficiency in an environment with RH>90%
Service life: precious metal catalysts can operate stably for more than 5 years

三、Innovative solutions for VOCs synergistic treatment

New composite catalysts (such as TiO₂/γ-Al₂O₃ system) can simultaneously achieve:
Dual functions of ozone decomposition and VOCs oxidation
Energy utilization rate increased by 30%-50%
Typical case: After a paint factory adopted this technology, the xylene removal rate increased to 98.6%

四、Technology development trends and challenges

Low-temperature catalysis: The development of high-efficiency catalysts below 80°C has become a research hotspot
Anti-poisoning performance: Improve tolerance to sulfides, halogens and other poisons
Modular design: Adapt to the rapid integration needs of devices of different sizes
