Katalizör Taşıyıcıları ve Substratlar

We supply ceramic and metallic catalyst carriers and substrates for automotive and industrial emission control systems. Designed as the supporting structure for catalytic coatings, our substrates provide high surface area for gas-solid reactions while balancing exhaust flow, thermal stability, and mechanical durability.

Available in different materials, cell densities, dimensions, and configurations, our catalyst substrates can be supplied for three-way catalysts (TWC), diesel oxidation catalysts (DOC), selective catalytic reduction (SCR) systems, and other exhaust aftertreatment applications.

Catalyst Carriers: Substrate Solutions for Emission Systems

High-quality ceramic and metallic carriers designed to support catalytic coatings for optimal emissions performance.

  • High Surface Area Structure
    Honeycomb structures provide a large surface area for catalytic coatings while maintaining controlled exhaust flow and pressure drop.
  • Multiple Cell Density Options
    Available in different CPSI configurations to meet application-specific requirements for surface area, exhaust flow, and catalyst performance.
  • Ceramic & Metallic Substrates
    Ceramic and metallic substrate options are available for different exhaust temperatures, packaging requirements, mechanical conditions, and catalyst applications.

What Is a Catalyst Substrate?

  • A catalyst substrate is the internal support structure used to carry the catalytic coating in an emission control system. Its honeycomb or structured surface provides a large contact area between exhaust gases and the catalyst coating, allowing the required chemical reactions to take place efficiently.
  • The substrate itself is not the main catalytic material. Instead, it provides the physical structure and surface area needed for the washcoat and active catalyst materials. Substrate design therefore has a direct influence on exhaust flow, heat management, durability, and overall catalyst performance.

Why Catalyst Substrate Design Matters

  • Surface Area：Provides the contact area required for catalytic reactions.
  • Exhaust Flow：The cell structure influences gas velocity and pressure drop.
  • Thermal Stability：The substrate must withstand repeated exhaust temperature changes.
  • Mechanical DurabilityThe structure needs to withstand vibration, thermal shock, and long-term exhaust operation.

Catalyst Carriers & Substrates FAQ

  • What is a catalyst substrate?
  • A catalyst substrate is the structured support that carries the washcoat and active catalytic materials inside an emission control system.
  • What materials are used for catalyst substrates?
  • Common materials include ceramic substrates such as cordierite and metallic substrates made from heat-resistant metal foils.
  • What does CPSI mean?
  • CPSI means cells per square inch. It describes the cell density of a honeycomb substrate and influences surface area and exhaust flow characteristics.
  • What is the difference between a catalyst carrier and a substrate?
  • In automotive emissions terminology, the terms are often used interchangeably to describe the physical support structure that carries the catalyst coating.
  • Can catalyst substrates be customized?
  • Yes. Dimensions, shape, cell density, material, and configuration can be customized according to application requirements.
  • What applications use catalyst substrates?
  • Catalyst substrates are used in TWC, DOC, SCR, DPF, GPF, and other automotive or industrial emission control systems.
