High Heat Resistant Cordierite Honeycomb Ceramics Honeycomb Catalyst Ceramic Monolith for Rto and Rco
Honeycomb ceramics serve as critical functional materials in catalysis, thermal regeneration, and material support applications. With tailored pore structure, chemical resistance, and thermal durability, they are indispensable in industries demanding high-efficiency reaction, heat management, and pollutant removal.
Honeycomb Ceramic Catalyst
Catalytic substrates are honeycomb ceramics coated with active catalytic materials, such as noble metals (Pt, Pd, Rh) or transition metal oxides. Their structured channels facilitate laminar or turbulent flow, optimizing reaction kinetics and contact efficiency.
Common Materials: Cordierite, alumina, zirconia
Cell Density: 100-600 CPSI (cells per square inch)
Functions
Promote contact between gas molecules and catalytic surface to accelerate redox reactions
Convert harmful gases like CO, HC, NOx into harmless components
Maintain catalytic efficiency under high-temperature conditions
Applications
Three-Way Catalytic Converters (TWC) in gasoline vehicles
Selective Catalytic Reduction (SCR) systems for diesel engines
Catalytic Oxidation Systems (RCO/CO) for industrial VOC abatement
Fixed-Bed Catalytic Reactors in chemical processing
Industries
Automotive emission control, environmental engineering, chemical manufacturing, coatings, electronics, etc.

Key Types & Shapes:
1.Catalyst Supports (e.g., Ceramic Substrates): The essential base for catalysts (e.g., precious metals) in emission control systems. Shapes: Primarily cylinders or rectangular blocks. Uses: Automotive catalysts (TWC, DOC, SCR, DPF, GPF), industrial SCR/SNCR DeNOx, VOCs catalytic combustion.
2.Thermal Regenerators (Heat Storage Bodies): Designed for cyclic heat absorption and release in systems like RTOs (Regenerative Thermal Oxidizers) and industrial furnaces. Delivers: Ultra-high thermal efficiency (>90%) and significant energy savings. Shapes: Large rectangular blocks dominate, sometimes custom shapes.
3.Filters (e.g., Particulate Filters):Trap and remove particulate matter (PM) or impurities via microporous channel walls. Shapes: Cylinders are common; specialized plugged structures for DPFs (Diesel Particulate Filters). Uses: Diesel exhaust filtration (DPF), molten metal filtration (Al, Cu, Fe), high-temperature gas cleaning.
4.Structured Packing: Replace random packing in chemical towers (distillation, absorption). Benefits: Higher efficiency, lower pressure drop, increased capacity. Shapes: Typically cylinders or rectangular blocks.
By External Shape: Available in STANDARD forms like Cylinders (Round) and Rectangular Blocks (Square/Long), plus CUSTOM shapes to fit specific reactor/furnace designs.
