Latest Patents

Among his notable inventions, Olivier Sonntag's latest patents include:

1. **Automotive Catalytic Aftertreatment System**: This invention pertains to a catalytic aftertreatment system designed for diesel engine exhaust gases. The system features a diesel oxidation catalyst (DOC) and an aftertreatment device positioned downstream. The aftertreatment device requires periodic heat treatment and is equipped with mechanisms to induce a temperature increase within it. Notably, the diesel oxidation catalyst includes an upstream zone with a length between 0.5 to 2 inches (12.7-50.81 mm) that exhibits increased oxidation activity for hydrocarbons compared to the remainder of the DOC.

2. **Zoned Catalyst for Treating Exhaust Gas**: In this innovative system, exhaust gas treatment is achieved through a dual-zone SCR catalyst setup. The first zone contains an iron-loaded medium- or large-pore molecular sieve with an initial ammonia storage capacity. The second zone contains a copper-loaded small-pore molecular sieve with enhanced ammonia storage capacity. This setup is strategically designed such that the first zone is upstream of the second zone in the normal exhaust gas flow, allowing for effective gas treatment.
