Catalytic Oxidizer – Efficient Solutions for Waste Gas & Wastewater Treatment
Product Name: Catalytic Oxidizer (CO) / Regenerative Catalytic Oxidizer (RCO)
Application: Industrial Air Pollution Control & Wastewater Treatment
Keywords: VOC Abatement, RCO, Catalytic Combustion, Ozone Catalytic Oxidation, Fenton Catalyst, Green Oxidation
Product Overview
A Catalytic Oxidizer is a pollution control technology that uses a catalyst to promote the oxidation of contaminants, converting them into harmless substances like carbon dioxide (CO₂) and water (H₂O). This technology is critical in two main industrial sectors:
- Air Pollution Control (VOCs): Used to destroy Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) from industrial exhaust streams. By using a catalyst, the oxidation occurs at significantly lower temperatures (300–450°C) compared to traditional thermal incineration, resulting in substantial fuel savings.
- Wastewater Treatment: Used to degrade recalcitrant organic pollutants in water. Technologies like Ozone Catalytic Oxidation and Fenton Catalytic Oxidation utilize catalysts (e.g., metal oxides) to generate hydroxyl radicals (·OH), powerful oxidants that break down complex organic molecules (like dyes, phenols, and pharmaceuticals) into biodegradable or harmless compounds.
Key Advantages
- High Destruction Efficiency: Achieves destruction removal efficiency (DRE) of 95% to 99%+ for VOCs and significant COD reduction in wastewater.
- Energy Efficiency: Catalytic oxidation requires lower operating temperatures than thermal oxidation, reducing auxiliary fuel consumption and operating costs.
- Lower Carbon Footprint: By facilitating complete oxidation at lower energy inputs, it reduces CO₂ emissions associated with the treatment process.
- Versatility: Effective on a wide range of pollutants, including solvents, hydrocarbons, and odorous compounds in air, and high-toxicity organics in water.

Applications
1. Air Pollution Control (VOC Abatement)
- Paint & Coating Industry: Treating exhaust from spray booths and drying ovens containing solvents like toluene and xylene.
- Chemical & Pharmaceutical: Controlling emissions from synthesis reactors and solvent recovery units.
- Printing & Packaging: Removing VOCs from rotogravure printing and laminating processes.
- Food Processing: Eliminating odors and organic fumes from cooking and rendering operations.
2. Wastewater Treatment (Advanced Oxidation)
- Ozone Catalytic Oxidation: Used for textile wastewater (decolorization), pharmaceutical wastewater (antibiotic degradation), and landfill leachate. The catalyst enhances ozone utilization, generating hydroxyl radicals to break down refractory organics.
- Fenton & Electro-Fenton: Used for chemical wastewater pretreatment. Newer heterogeneous Fenton catalysts reduce sludge production compared to traditional liquid Fenton processes.
- Green Chemical Synthesis: Utilizing catalytic oxidation with air or hydrogen peroxide as “green oxidants” to replace toxic reagents like chromates in chemical manufacturing.
Packaging & Storage
- Air Catalysts: Typically supplied as ceramic monoliths or structured packing within a steel housing (skid-mounted).
- Water Catalysts: Supplied as granular media (e.g., 3-6mm pellets) in bulk bags or drums.
- Storage: Store in a dry environment. Catalysts must be protected from moisture, dust, and “catalyst poisons” (such as lead, mercury, or sulfur compounds) which can permanently deactivate the active sites.
