High-Efficiency Nitrogen Oxide Mitigation: The Cu-Zeolite SCR Solution

In the evolving landscape of global emission standards, Cu-Zeolite Selective Catalytic Reduction (SCR) technology stands as the gold standard for Nitrogen Oxide (NOx) control in mobile sources. As heavy-duty engines and maritime vessels face stricter compliance mandates, the integration of advanced catalytic materials is no longer optional—it is a necessity for sustainable operation.

Applications and Versatility

The GRACE Cu-SCR catalyst is engineered specifically for high-performance mobile environments:

Road Transport: Heavy-duty trucks, logistics vehicles, and urban buses requiring compliance with Euro VI or China VI standards.

Non-Road Machinery: Excavators, agricultural tractors, and mining equipment operating under variable loads.

Marine Power: Ocean-going vessels and inland shipping complying with IMO Tier III regulations.

Technical Advantages

The GRACE series offers distinct superiority over traditional catalysts:

Superior Thermal Stability: Maintains structural integrity during DPF active regeneration cycles (exceeding 650°C).

Wide Temperature Window: Exceptional activity starting as low as 150°C, ensuring effective treatment during cold starts and low-load idling.

High N2 Selectivity: Minimizes the formation of N2O (Nitrous Oxide) bypass gas.

Technical Specifications

Manufacturing Process

Substrate Preparation: High-precision coating of ceramic or metallic honeycombs.

Slurry Synthesis: Precise ion exchange of copper into the zeolite framework for maximum active sites.

Precision Coating: Advanced "washcoat" application to ensure uniform distribution and low pressure drop.

Calcination: High-temperature curing to anchor the catalyst and enhance durability.

Usage Instructions & Maintenance

Installation: Ensure the gas flow direction matches the arrow on the housing.

Urea Injection: Calibrate the AdBlue/DEF dosing system to prevent "Ammonia Slip" or crystallization.

Fuel Quality: Use ultra-low sulfur diesel (ULSD) to prevent sulfur poisoning of the active copper sites.

After-Sales & FAQ
