Title: The Innovations of Stéphane Kieger
Introduction
Stéphane Kieger is a notable inventor based in Haguenau, France. He has made significant contributions to the field of environmental technology, particularly in the reduction of nitrogen oxides (NOx) emissions. His innovative approach has led to the development of a unique process that utilizes zeolite catalysts for selective catalytic reduction.
Latest Patents
Kieger holds a patent for a process aimed at the removal of nitrogen oxides from gases through selective catalytic reduction (SCR) using ammonia over zeolite catalysts. This process is particularly noteworthy as it avoids the formation of nitrogen protoxide. The patent details the use of zeolites that are partially exchanged with copper, specifically faujasites, where the copper does not predominantly occupy the small cages, such as the sodalite cages of the faujasites. The invention emphasizes the importance of certain mixed rare-earth/copper zeolites, and it correlates the selectivity of NOx reduction to the TPR diagram of the catalysts.
