Nitrate waste gas treatment catalyst (RN-302 catalyst) is a high-performance catalytic material designed to efficiently remove nitrogen oxides (NOₓ) and other harmful nitrogen-based pollutants from industrial waste gas streams. Engineered with optimized metal-supported formulations, it enhances reaction kinetics, promotes selective catalytic reduction, and ensures prolonged operational stability. This catalyst is widely used in chemical manufacturing, fertilizer production, and large-scale industrial emissions control, delivering reliable performance for sustainable air purification processes.
Product Overview
The Nitrate Waste Gas Treatment Catalyst (RN-302) uses ammonia as a reducing agent to effectively treat NOx in industrial flue gas. The catalyst promotes the reaction between NOx and ammonia under specific conditions, converting them into harmless nitrogen and water. This catalyst does not require hydrogen reduction, has a low startup temperature, and operates efficiently over a broad temperature range. By adjusting the NOx to ammonia ratio, the stable operation of the exhaust treatment system and effective NOx removal can be ensured.
Key Features
- High NOx Conversion Efficiency: Effectively reacts NOx with ammonia in the exhaust gas, converting them into nitrogen and water for purification.
- Low Startup Temperature: The startup temperature ranges from 150°C to 200°C, with a typical operating temperature of 200°C to 250°C, meeting NOx elimination requirements.
- No Hydrogen Reduction Required: Does not require hydrogen for reduction, simplifying the operational process.
- Adjustable Operation: The NH₃/NOx ratio (1.1~1.2) can be adjusted to optimize catalyst working conditions and exhaust treatment efficiency.
- Good Stability: The catalyst demonstrates excellent stability over extended use, maintaining high-efficiency performance for continuous exhaust gas treatment.
Applications
- Industrial Flue Gas Purification: Primarily used for NOx treatment in nitric acid plant exhaust, thermal power plants, and other industrial flue gases.
- Environmental Protection: Widely used in environmental protection and waste gas treatment sectors, helping companies meet emission standards.
- Chemical Industry: Applied in NOx elimination during the production of nitric acid, reducing pollution emissions.
- Energy Industry: Controls NOx emissions in coal-fired power plants and other combustion processes.
