Title: Innovations of Catherine Zivkov
Introduction
Catherine Zivkov is a prominent inventor based in Narosse, France. She has made significant contributions to the field of zeolite synthesis, holding a total of seven patents. Her work focuses on innovative processes that enhance the properties and applications of zeolites.
Latest Patents
One of her latest patents involves the synthesis of zeolites of faujasite structure. This process provides a method for preparing zeolites with a Si:Al ratio higher than 1. The method includes producing a reaction mixture with a pH greater than 10, containing water, sources of tetravalent silicon and trivalent aluminum, hydroxide ions, and a structuring agent. The resulting aluminosilicate gel is then crystallized into a zeolite precursor, which is subsequently calcined to produce the final zeolite. Another notable patent addresses the dealuminization of synthetic zeolites with large pores. This process involves acid leaching of the raw zeolite, resulting in dealuminized zeolites that serve as effective catalysts and selective organophilic adsorbents.
