Document Type and Number:
WIPO Patent Application WO/2019/200989
Kind Code:
A1
Abstract:
A process for preparing a porous oxidic material which comprises micropores and mesopores and which comprises a zeolitic material having a framework type AEI and having a framework structure comprising a tetravalent element Y, a trivalent element X and oxygen, wherein said micropores have a pore diameter determined according to nitrogen adsorption-desorption at 77 K of less than 2 nm and wherein said mesopores have a pore diameter determined according to nitrogen adsorption-desorption at 77 K in the range of from 2 to 50 nm, said process comprising (i) preparing a synthesis mixture comprising a zeolitic material having a framework type FAU and having a framework structure comprising the tetravalent element Y, the trivalent element X and oxygen, water, a source of base, a first organic structure directing agent being an AEI framework type structure directing agent, a second organic structure directing agent comprising a dimethyl-octadecyl [3- (trimethoxysilyl) propyl] ammonium cation containing compound, and seed crystals; (ii) subjecting the mixture obtained in (i) to hydrothermal crystallization conditions comprising a crystallization temperature in the range of from 90 to 200 ℃, obtaining a mother liquor comprising the porous oxidic material comprising said zeolitic material having a frame-work type AEI.
