Soot trap catalytic filters

Genset exhaust is creating a major environmental concern with toxic fumes and soot generated at random depending on the age and model of the diesel genset. The purposely constructed catalytic soot trap abator was developed for use on Stationary Genset Diesel Engines up to 3 MW where sulphur content in the fuel could be as high as 350 PPM.

Soot trap catalytic filters









For soot removal from genset engines, the catalysed soot trap will be combined with a non precious metal pre-catalyst. This pre-catalyst will act as exhaust pre-conditioner which reduces the SOF content of the particulates.


The catalytic soot filter itself comprises of a ceramic “Wall Flow” Particulate Filter that is coated with a combination of a highly active base metal wash coat and a specially formulated "Precious Metal” coating. The “Wall Flow” Particulate Filter will be contained within a stainless steel outer casing.


This combination is designed to dramatically reduce the levels of Carbon Monoxides (CO), Hydrocarbons (HC), and Particulate Matter (PM) present within the exhaust output of a diesel engine by use of an oxidation process.

The Filter has reasonable sound attenuation characteristics for the removal of both high and low frequencies, and hence requires less further silencing. This system has been specifically designed to operate where the “Duty Cycle” of the diesel engine is operating at temperatures between  275-550 °C.

The catalyst coating on the Filter element effectively lowers the “Light Off” temperature at which soot particles will combust. Therefore it promotes continuous and automatic regeneration of the soot particles that have been collected within the filter element.
