Honeycomb denitration catalyst is an efficient environmental material used for removing nitrogen oxides (NOx) from industrial flue gas. Its core features are as follows:
Structural Characteristics
Honeycomb design: Multi-channel parallel structure offering large specific surface area, low pressure drop, and strong anti-clogging performance, suitable for high-dust flue gas environments.
Material: TiO₂-based carrier with V₂O₅-WO₃/MoO₃ as active components, resistant to high temperatures (300-400°C).
Working Principle
Utilizing Selective Catalytic Reduction (SCR) technology, it converts NOx into harmless nitrogen (N₂) and water (H₂O) in the presence of ammonia (NH₃), achieving a denitration efficiency of over 90%.
Applications
Widely used in industrial flue gas treatment systems such as coal-fired power plants, steel mills, cement plants, and waste incineration facilities to meet environmental emission standards (e.g., ultra-low emissions).
Advantages
High activity and long service life (typically 3-5 years);
Strong adaptability with customizable cell density (e.g., 15-25 cells per square inch) for various working conditions;
Environmentally friendly and energy-saving, supporting emission reduction goals.
Precautions
Protection against poisoning by arsenic, alkali metals, etc., is essential. Regular ash cleaning and maintenance are required to extend service life.
Summary: The honeycomb denitration catalyst is a core component of SCR denitration systems, providing highly efficient and stable performance to support industrial pollution control.
