Title: Innovations and Contributions of Qi Fu in Zeolite Compositions

Introduction

Qi Fu, located in Solon, OH, is a prominent inventor with a total of 11 patents to his name. His work primarily focuses on advancements in the field of zeolite compositions, particularly in processes that enhance the efficiency and effectiveness of catalytic systems.

Latest Patents

One of Qi Fu's latest patents is for a "Process for preparing iron(III)-exchanged zeolite composition." This innovative process pertains to the formation of metal-promoted molecular sieves, specifically Iron(III) exchanged zeolites, ideally in chabazite form. The method involves combining zeolite with Iron(III) cations in an aqueous medium, typically at a pH of less than about 7, often utilizing a buffering material. Notably, this process achieves nearly complete Iron exchange while effectively removing unwanted cations like sodium and hydrogen from the zeolite. An Iron(III)-exchanged zeolite produced through this method can contain as little as 2,000 ppm of cation and at least 1% by weight of Iron(III). Additionally, Qi Fu's patent discusses catalysts and exhaust treatment systems incorporating the Iron(III)-exchanged zeolite, emphasizing their applicability in various industrial contexts.

Another significant patent involves "Selective catalytic reduction articles and systems." This technology aims to optimize high NOx conversion rates while minimizing NO formation, making it particularly valuable for diesel engine exhaust treatment. The patented systems feature zoned coatings—one layer consisting of a steam-activated iron-containing molecular sieve and another comprising a high copper-containing molecular sieve, allowing for enhanced performance.
