Abstract
A process for the preparation of a copper containing zeolitic material having CHA framework structure and a composition comprising the molar ratio (n YO2):X203 wherein X is a trivalent element, preferably Al, Y is a tetravalent element, preferably Si, and wherein n is preferably at least 20. The process comprising the preparation of an phosphor-free aqueous solution containing at least one source for X203 and at least one source for YO2, at least one structure directing agent suitable for the preparation of a zeolitic material having CHA framework structure, and at least one Cu source, and the process further comprising the hydrothermal crystallization of said aqueous solution obtaining a suspension containing the copper containing zeolitic material having CHA framework structure.
