MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202647084325 A) filed by Ifp Energies Nouvelles on July 09, 2026, for Method For Synthesising An Izm-10 Aei Zeolite Having A Very High Purity In The Presence Of A Nitrogen-Containing Organic Structuring Agent.
Inventors include Harbuzaru, Bogdan; Berthout, David; Llido, Eric; and Martinez Franco, Raquel Number.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The invention relates to a method for preparing an IZM-10 AEI zeolite comprising at least mixing, in an aqueous medium, a FAU- type zeolite having a SiO2(FAU)/Al2O3(FAU) molar ratio of between 10 and 60 inclusive and a mass percentage of sodium in cation form of less than 0.005%, a nitrogen-containing organic compound R, wherein R is (6R,10S)-6,10-dimethyl-5-azoniaspiro[4,5]decane in its hydroxide form, and optionally sodium hydroxide, followed by a step of hydrothermally treating the precursor gel obtained at the end of step i). The invention also relates to the AEI zeolite having a SiO2/Al2O3 molar ratio of between 10 and 60 inclusive having a purity of greater than or equal to 98% by weight, preferably greater than or equal to 99% by weight, in partially or completely protonated form, obtained using the method.
