About Catalyst - TWC DOC DPF SCR AOC

Product Description

Ceracomb has its own technology to make and supply ceramic honeycombs and catalysts all together. we coat catalysts into theceramic substrates for each purpose. Ceracomb supplies their catalysts for Automobiles and various industries.

1. DOC (Diesel Oxidation Catalyst) - DOC Catalyst efficiently oxidizes SOF among CO, HC, PM from diesel exhaust.

2. DPF (Diesel Particulate Filter)- DPF(Catalyzed DPF) oxidizes CO and HC which are not eliminated completely by DOC and help soot regeneration.

3. SCR (Selective Catalytic Reduction) - SCR Catalyst removes NOx from diesel vehicles. In the SCR process, NOx

4. AOC (Ammonia Oxidation Catalyst) - It is a catalyst to remove ammonia emitted from semiconductor processing and SCR post-processing devices.

5. TWC (Three Way Catalyst) - TWC converts HC, CO, NOx exhausted from gasoline vehicles into CO2, H2O, N2

FAQ's of Catalyst - TWC DOC DPF SCR AOC:

Q: How does the Catalyst - TWC DOC DPF SCR AOC achieve high filtration efficiency in automotive exhaust systems?

A: Utilizing advanced substrate technology with high cell density (100-600 CPSI) and a superior precious metal coating, the catalyst achieves over 99% particulate matter removal in the DPF stage. Its optimized surface area ensures excellent catalytic activity, enabling efficient oxidation and reduction of harmful emissions to meet stringent standards.

Q: What types of vehicles and fuel systems are compatible with this catalyst system?

A: This catalyst is engineered for maximum versatility and is compatible with gasoline, diesel, CNG, and LPG engines. It suits passenger cars, commercial vehicles, heavy-duty trucks, and buses, and can be customized to fit major OEM models as per specific requirements.

Q: When should the catalyst be inspected or maintained for optimal performance?

A: While the catalyst is designed for low maintenance and long service life (over 100,000 km under normal conditions), periodic visual inspections are recommended. Maintenance primarily involves checking for physical blockage or surface contamination to ensure peak filtration and conversion efficiency.

Q: Where can the catalyst system be installed within a vehicle's exhaust system?

A: The catalyst is typically installed as part of the exhaust after-treatment assembly. Depending on vehicle design, it may be direct-fit, clamp-on, or flange-mounted. Its customizable shapes and sizes allow precise integration into a wide range of automotive exhaust configurations.

Q: What is the process for selecting the right catalyst configuration for a specific application?

A: Selection is based on engine type, desired emission standard compliance (such as Bharat Stage VI, Euro 6, or US Tier 4), substrate preferences, available space, and operating conditions. Consultation with the supplier or manufacturer ensures the catalyst meets technical and regulatory needs, including custom OE numbers or dimensions.

Q: How does using this catalyst system benefit vehicle owners and fleet operators?

A: The catalyst offers high conversion efficiency, durability, and low back pressure-reducing emissions without compromising engine performance or fuel economy.
