Exhaust SCR Denox Catalyst for Coalbed Methane Generator Sets (Euro II-Ⅴ Standard
SCR Catalyst Coalbed Methane Generator Set Reducing Exhaust Emission
Product Description
1. Introuduction
Our advanced Selective Catalytic Reduction (SCR) system is designed to efficiently reduce NOx emissions from coalbed methane generator sets, ensuring compliance with Euro II through Euro V standards. The system utilizes a urea-based (AdBlue) reducing agent, which reacts with NOx in the presence of a high-performance honeycomb-structured SCR catalyst, converting harmful pollutants into nitrogen (N₂) and water (H₂O)—completely harmless to the environment and human health.
Key Features & Optimizations
1. High-Efficiency SCR Catalyst
Honeycomb Ceramic Monolithic Design: Coated with vanadium (V₂O₅-WO₃/TiO₂) or zeolite (Cu/Fe-zeolite) catalysts for maximum NOx conversion (>90%).
Wide Operating Temperature Range (200–450°C): Enhanced low-temperature activity for stable performance under variable loads.
Poisoning Resistance: Special formulations prevent sulfur (H₂S) and soot degradation, ensuring long-term durability.
2. Smart Urea Dosing & Control System
Real-Time NOx Monitoring: Upstream/downstream NOx sensors provide feedback for precise AdBlue injection.
Adaptive Dosing Algorithm: Maintains optimal NH₃/NOx ratio (0.9–1.1) to maximize NOx reduction while
minimizing ammonia slip (<10 ppm).
OBD Compliance (Euro IV/V): Integrated On-Board Diagnostics for fault detection (e.g., urea level, catalyst efficiency loss).
3. Optimized Exhaust Flow & Mixing
Static Mixers & Turbulators: Ensure uniform NH₃/NOx distribution before entering the catalyst, improving reaction efficiency.
Thermal Management: Insulated exhaust piping maintains optimal SCR operating temperature (250–400°C), even at low engine loads.
4. Compact & Robust Packaging
Integrated Muffler Design: The SCR catalyst is packaged within the engine exhaust muffler, saving space and simplifying installation.
Corrosion-Resistant Housing: Stainless steel or aluminized steel construction for harsh environments.
