2. Main Products of Lanfeng

　　

 

1. Honeycomb Ceramic Substrate

Honeycomb ceramic substrate produced by our company mainly includes straight-through honeycomb ceramic substrate and wall flow honeycomb ceramic substrate(DPF substrate for short), among which, DPF substrate can be divided into cordierite DPF substrate and silicon carbide DPF substrate according to different materials.

CN VI Cordierite GPF	CN VI Cordierite DPF	CN VI Silicon Carbide DPF
CN VI 400 mesh Substrate	CN VI 600 mesh Substrate	CN VI 750 mesh Substrate
Large Size Straight-through Substrate	Stationery Source with Straight-through Substrate	A Straight-through Substrate Used for Gasoline Engines

 

2. Diesel Exhaust Purification Catalyst

The main pollutants of diesel engine are CO, HC, NOx and PM. Catalytic purification is the mainstream technology of diesel exhaust after-treatment at present.

The principle of Catalytic Purification：

　　

 

3. DOC Catalyst

DOC catalysts are mostly precious metals based catalyst such as platinum (Pt), palladium (Pd) etc.

Function and Purpose

It oxidizes HC, CO and soluble organic SOF in diesel exhaust;

Coping with SCR, DOC oxidizes NO in diesel exhaust into NO₂, creating thermal energy to improve catalysts performance under low temperature.

Coping with cDPF, DOC oxidizes NO in diesel exhaust into NO₂, which serves as the oxidation of carbon soot particles achieving cDPF passive regeneration; Soot can also directly oxidize injected fuel HC to improve inlet temperature of cDPF catalyst, and achieve active regeneration of cDPF by burning carbon particles

DOC catalyst can be used for CN V, CN VI emission standard for road application and CN IV and above emission standard for non-road application.

HC+O₂→CO₂+H₂O 　　CO+O₂→CO₂ 　　SOOT+O₂→CO₂(Partial conversion) 　　PAH+O₂→CO₂+H₂O; 　　NO+O₂→NO₂

 

4. CDPF Catalyst 

Through the filtering of the wall-flow substrate, the PM can be captured by the wall of the DPF. Under the chemical reaction of catalyst, the captured PM will be oxidizes as CO₂ and H₂O. under certain temperature conditions.

　　

 

5. SCR Catalyst 

Diesel SCR catalysts mainly consist of V-SCR catalysts and molecular sieve SCR catalysts. V-SCR catalyst can meet CN V of diesel engine and non-road CN III emission standards of small and medium power diesel engine; Molecular sieve SCR catalyst is divided into Cu - SCR, Fe - SCR and Cu&Fe - SCR, mainly used for road diesel engine CN Ⅵ and non-road diesel engine IV and above emission standard.

SCR Catalyst Reaction Mechanism 　　4NO+4NH₃+O₂→4N₂+6H₂0 　　NO+NO₂+2NH₃→2N₂+3H₂0 　　8NH₃+6NO₂→7N₂+12H₂O
