We supply complete gas cleaning systems for sources of NOx emissions, such as diesel and gas engines installed in cogeneration plants, peak shaving power units, gas compression stations and portable power modules.

The main features of the honeycomb type catalysts used in the SINOx^® System are large specific surface areas, high activity and resistance against chemical substances, which allow compact dimensions with low exhaust gas backpressures and low ammonia slip.

Beside its main function, the reduction of nitrogen oxide, the ceramic catalyst is able to reduce carbon monoxides (CO), hydrocarbons (HC) and particles (PM).

Our oxidation catalysts enable high performance CO and HC control and are able to be employed as presilencer with around 10 dB(A) to 15 dB(A) sound level silence.

For stationary diesel and gas engines, the SINOx^® System is installed in the exhaust duct and consists of the SINOx^® catalytic reactor, a control unit based on either open or closed-loop control, and a dosing unit for the reducing agent.

The control unit ensures optimum and safe operation and regulates the injection of reducing agent according to the required load of the engine. This intelligent control equipment guarantees minimum consumption of reducing agent to keep your operating costs low.

Johnson Matthey has equipped hundreds of power units with our SCR-systems for stationary plants with diesel and gas engines worldwide, with a total engine power of over 1,300 MW with SINOx^® exhaust gas cleaning systems.
