1. Catalysis device adopts the ceramic honeycomb as the carrier; Use cordierite as the main composition of the stabilizer, Which coating the active oxide of rare- Earth complex cover; And make rare- Earth and little noble metal as catalyst, By burned and drying out to complete. 2. Catalysis devices outer shell adopts corrosion resistant plate presure forming, Encapsulation welding to complete. Its beautiful and burliness. 3. Using the imported cushion to be apart and fix between the carrier and shell, For heat insulation and shock absorption, And it also has good capability in prevent from thermal shock. 4. Catalysis devices is designed as olive streamline shape according to the fluid mechanics principle, The pressure loss is small, And its matched with the engine, So it doesnt affect its motivity and economics function. 5. Due to the catalysts proporting is fitting, So the conversion rate of dusty gas is high, Meanwhile, The three effect type catalysis device is applicable to the closed loop electricity- Gushed system(EFI), New vehicle and replacing vihicle. 6. The unleaded gas that catalysis device was requested to use , The leaf of content is below 5MG/ L, Otherwise would affect the service life of the catalysis device. 7. Use the oxidize type catalysis device in the using car, And install the two complement oxygen equipment at the point with waste gas waste gas recycle, Also reduce greatly the exhaust.

OOxygen storage materials (HS 280530) In order to oxidize CO and HC, A three- Way catalytic converter also has the capability of storing the oxygen from the exhaust gas stream, Usually when the air fuel ratio goes lean. When insufficient oxygen is available from the exhaust stream the stored oxygen is released and consumed. Our company manufactured high quality oxygen storage materials. Oxygen storage capacity are showed in below chart. Texture properties and OSC of Oxygen Storage Material(OSM) OSM SBET / M2g- 1 Vs / Cm3. G- 1 Avg. Pore Size/ Nm Osc / Umol.

Our company has successfully developed many types of three-way catalytic converters, which are suitable for many types of vehicles and meet the emission standard above E3. We can provide universal catalytic converters, direct fit catalytic converters, pre-cat catalytic converters and specialty catalytic converters.
This technique is the production jointly exploited by my company and professor Chen Shaoping from Nanchang university application chemical graduate school, it has following good characteristics: Using honeycomb ceramics carrier that has many advantages, such as low cost, strong adhesive and active ingredient, long life etc. . Adopting late-model of rare earths (material Zirconium and Titanium) to advance the heat resistance and activity of catalyst. Introducing transitional metal, alkaline earth metal and active material of little precious metal that has plenty of excellences, such as high purification rate, and low burning temperature etc.. Making use of new-style of oxygen storing stuff that reduces the burning temperature of catalyst and complete transformation. The catalytic converter applied and produced by this technique has past the test of 123 national exhaust gas test center and Tianjin university burning internal-combustion engine lab, the result indicates: using this cat that can make the emission standard reach European no.3 and meet the technique requirements the converter product demands. The special exhaust gas catalytic converter for CNG engine is composed of two parts, that are catalyst of honeycomb ceramics and metal shell, the main elements is: The exhaust gas pass through the catalyst of honeycomb ceramics, the active ingredient of catalyst (mostly are metal oxide of rare earths, precious metal and transitional metal) is able to carry out the catalysed reaction fully under the temperature condition of 200 to 300 celsius degree aboved converting the harmful element such as CO, HC, NOX etc. to innocuous water, carbon dioxide and nitrogen. a. key technique The core of this programm is the exhaust gas decontamination technique of CNG engine, which belongs to three-way decontamination catalyst technique, and is the main means of dealing with exhaust gas of CNG engine at present. The main chemical reaction formula as follows. Oxidation reaction: HC+O 2 =H 2 O+CO 2 Deoxidization reaction: NOx+HC+CO=N 2
