Disclosed herein is a continuous process for preparing zeolitic material with a CHA-type framework structure comprising SiOand XOand the zeolitic material so-obtained. The processes comprises (i) preparing a mixture comprising one or more sources of SiO, one or more sources of XO, seed crystals, one or more tetraalkylammonium cation RRRRN-containing compounds as structure directing agent, and a liquid solvent system; (ii) continuously feeding the mixture prepared in (i) into a continuous flow reactor at a liquid hourly space velocity; and (iii) crystallizing the zeolitic material with a CHA-type framework structure from the mixture in the continuous flow reactor.

A catalyst for the selective catalytic reduction of NOx comprises a zeolitic material which comprises (A) one or more zeolites having a GME framework structure containing YOand XO, and optionally further comprises one or more zeolites having a CHA framework structure containing YOand XO, and/or comprises, (B) one or more zeolite intergrowth phases of one or more zeolites having a GME framework structure containing YOand XOand one or more zeolites having a CHA framework structure containing YOand XO, wherein Y is a tetravalent element, and X is a trivalent element, and the zeolitic material contains Cu and/or Fe as non-framework elements in an amount ranging from 0.1 to 15 wt. % calculated as the element and based on 100 wt. % of YO contained in the zeolitic material. Also provided are a process for its preparation, and a use in a method for the selective catalytic reduction of NOx.
