In the pursuit of cleaner industrial air, Selective Catalytic Reduction (SCR) technology plays a pivotal role. A key element in many SCR systems is the honeycomb catalyst structure. This design offers significant advantages in terms of efficiency and performance, making it a preferred choice for many industrial applications. As a prominent manufacturer of SCR catalysts, we specialize in producing high-quality honeycomb structures tailored to meet diverse industrial needs.

The Advantage of Honeycomb Design

The honeycomb structure is fundamental to the effectiveness of SCR catalysts. This intricate design features a matrix of small, parallel channels that provide an exceptionally large surface area within a compact volume. This high specific surface area is critical because it maximizes the contact between the exhaust gases (containing NOx) and the active catalytic material. More contact points mean a more efficient conversion of NOx into nitrogen and water. Furthermore, the controlled flow through these channels minimizes pressure drop, which is essential for the overall energy efficiency of the exhaust gas treatment system.

Key Benefits of Honeycomb SCR Catalysts:

  • High Surface Area: The primary advantage is the vast surface area per unit volume, leading to superior catalytic activity and NOx removal efficiency.
  • Low Pressure Drop: The carefully designed channels allow for efficient gas flow, reducing backpressure on the engine or industrial process.
  • Mechanical Strength: Honeycomb structures, when properly manufactured, offer good mechanical integrity and resistance to thermal shock.
  • Uniform Gas Distribution: The consistent channel design ensures even distribution of exhaust gases across the catalyst, preventing channeling and localized over-saturation.
  • Optimized for Various Dust Concentrations: We can manufacture honeycomb catalysts with different hole pitches (e.g., 9x9, 18x18, 25x25) to accommodate varying dust concentrations in flue gases, ensuring optimal performance and longevity. For instance, finer pitches (like 15x15 or 18x18) are suitable for coal-fired units with high to medium dust, while coarser pitches (like 40x40 or 55x55) are preferred for gas-fired units with very low dust.

Material Composition and Performance Characteristics

Our honeycomb SCR catalysts are typically based on a TiO2 structure, incorporating active components such as V2O5 and WO3. This composition provides excellent thermal stability and catalytic activity across a wide operating temperature range, ensuring effective NOx reduction. They are designed for high durability, with a chemical service life often extending to 24,000 hours and a mechanical service life of up to 50,000 hours. Features like low SO2 conversion rates (around 1%) and minimal NH3 slip are standard, contributing to a cleaner and safer overall process.
