Exhaust SCR Denox Catalyst for Coalbed Methane Generator Sets (Euro II-Ⅴ Standard

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.
