Title: Innovations by Juliane Theis in Nitrogen Oxide Catalysts

Introduction

Juliane Theis is a prominent inventor based in Karlstein, Germany. She has made significant contributions to the field of catalytic technology, particularly in the area of nitrogen oxide reduction. With a total of 2 patents, her work focuses on improving the efficiency and effectiveness of catalysts used in lean burn engines.

Latest Patents

One of her latest patents is a method for determining the instant at which a nitrogen oxide storage catalyst is switched from the storage phase to the regeneration phase. This innovation addresses the challenges faced during the regeneration of nitrogen oxide storage catalysts, particularly when premature load changes in the engine can lead to incomplete emptying of the catalyst. By utilizing the residual filling level that remains after incomplete regeneration, her method enhances the accuracy of filling level calculations during subsequent storage phases.

Another notable patent involves a catalyst designed to lower the amount of nitrogen oxides in the exhaust gas from lean burn engines. This catalyst comprises active aluminum oxide, magnesium oxide, and at least one noble metal from the platinum group. The unique feature of this catalyst is that the magnesium oxide forms a homogeneous mixed oxide with aluminum oxide, present in a concentration of about 1 to 40 wt.-%, based on the total weight of the mixed oxide.
