Clean-up Catalysts
Catalysts for engines clean-up

The growing concern to promote mobility means with a minimum footprint on our ecosystem, and pending technological breakthroughs towards wholly electrical solutions, current approaches based on the internal combustion engine both improve their performance and should benefit from clean-up measures.
Thus the standards bodies are implementing progressive reductions in the emissions levels allowed for both petrol and diesel engines.
The clean-up solutions for these power units will need to be compact.

Particular expertise in the integration of active phases:

Gas processing applications are often subject to blockage constraints particularly in the case of on-board pollution control systems (cars, trucks, construction and mining equipment, boats, etc.). Indeed increasingly stringent standards and coverage of more and more pollutants require system integrators to "stack" clean-up functions.
This is why CTI has developed catalytic phase integration technology and expertise in particulate filters to allow the compaction of the filtration process of soot from diesel engines and oxidative and/or reductive catalytic functions (for example to treat NOx).
This method has the feature of allowing, compared to known technologies for catalyst coating (washcoat), loading of large amounts of catalyst without putting prohibitive strain on the filter counter-pressure (see example below). It also enhances the interaction between the catalyst and the gas to be treated by taking advantage of the surface developed by the filter porosity.
This technology can be extrapolated for stationary applications.

Industrial Processes

Heterogeneous catalysis allows a multitude of conversions in many cases for degrading the regulated gaseous pollutants. Although to date the constraints are the same as for transportation, environmental pressure will tend to close this gap.

CTI is also able to provide substrates of different geometries, porosities and compositions for guard bed type applications, or other arrangement between DeNOx type catalysts and DeH2S products.
