Johnson Matthey - Model SINOx -Honeycomb SCR Catalyst
Johnson Matthey’s SINOx® extruded honeycomb SCR catalysts achieve maximum NOx reduction to control air pollution from industries and combustion sources worldwide. Johnson Matthey is a world leader in catalytic emission control and has manufactured extruded SINOx SCR catalysts since 1987 to control air pollution from industries and combustion sources worldwide. Our homogeneous extruded honeycomb SCR catalysts consist entirely of catalytically active materials such as oxides of titanium, vanadium and tungsten, and are therefore more active than coated SCR catalysts. SINOx honeycomb SCR catalyst is supplied pre-installed in element frames or modules for durability and easy handling.
- High specific surface area
- High activity
- Pressure drop optimized
- Variable pitch, length
- Cell densities from 6 cpsi to 300 cpsi
Extruded SINOx honeycomb SCR catalyst can be produced in a wide variety of cell densities (pitch sizes) to accommodate diverse operating conditions and achieve maximum NOx reduction to control air pollution at the lowest possible backpressure.
Cell densities for a wide range of applications:
- Low cell density catalyst: Coal-fired power plants, high-dust processes such as cement manufacturing, high-dust biomass and waste incineration processes
- Medium cell density catalyst: Moderate- to low-dust applications, HFO-fueled marine engines, gas turbines, steam methane reforming, locomotive engines
- High cell density catalyst: ULSD engines and clean-fuel applications such as natural gas engines
Vanadia titania SCR catalyst is very active for the reduction of NOx and is resistant to poisoning by sulfur. SINOx® honeycomb SCR catalyst is therefore ideal for controlling air pollution from combustion sources such as marine engines and HFO or MDO-fired power plants. The catalyst composition can be tailored to achieve maximum NOx reduction depending on the temperature, so there is a SINOx® honeycomb SCR product for almost every application.
Specially tailored SCR formulations:
- Higher V loading maximizes NOx reduction at low temperature (< 300°C)
- Lower V loading minimizes NH3 oxidation high temperatures (> 425°C), improving high-temperature NOx conversion
