Shop OEM catalytic converters here. catalytic oxidizer. In the catalytic oxidizer, a catalyst is used to increase the rate of the combustion reaction, allowing the combustion to occur at lower temperatures. Because the catalytic process operates at a lower temperature than the thermal process, less auxiliary fuel may be required in the catalytic process to preheat the waste gas. The ideal reaction has an optimal temperature range between 630 and 720 K (357 and 447 °C), but can operate as low as 500 K (227 °C) with longer residence times. The minimum effective temperature depends on the various fuels, gas constituents, and catalyst geometry. Other possible reductants include cyanuric acid and ammonium sulfate. [3]. .

The cooling water flows between the walls, thus cooling the outside of the exhaust system while the catalytic converter is able to operate at the required high temperature. Sensors also measure the temperature and adjust engine cooling as needed. Low weight and minimum risk of corrosion. The catalytic converter reaches normal operating temperature usually between 400 and 600 degrees Fahrenheit. When the converter reaches this temperature it then starts to burn off the harmful emissions such as hydrocarbons, nitrogen compounds and carbon monoxide. Temperatures that are out of this range can be an indication the converter is. This "cat" as it is sometimes called has a wide range of temperature operations which begins working when it reaches between 200°F (98°C) to 400°F (204°C). From there its normal operating temperature can be upwards of 500°F (260°C). 2. With Sodium Hydroxide. To clean the catalytic converter with sodium hydroxide, you'll first need to remove it from the vehicle. Then, soak the inside of the converter using a spray bottle. Make sure to spray into the cat from both sides. Let the cat sit for 20 minutes or longer so the chemicals have time to work. This can super-heat the converter far above normal operating conditions and cause a meltdown. Possible causes are an incorrect fuel mixture, incorrect timing, corroded spark plugs, a faulty oxygen sensor, faulty fuel injector or a malfunctioning check valve.
