Abstract
A process for preparing a zeolitic material containing YOand XO, where Y and X represent a tetravalent element and a trivalent element, respectively, is described. The process includes (1) a step of preparing a mixture containing one or more structure directing agents, seed crystals, and a first zeolitic material containing YOand XOand having FAU-, GIS-, MOR-, and/or LTA-type framework structures; and (2) a step of heating the mixture for obtaining a second zeolitic material containing YOand XOand having a different framework structure than the first zeolitic material. The mixture prepared in (1) and heated in (2) contains 1000 wt % or less of HO based on 100 wt % of YOin the framework structure of the first zeolitic material. A zeolitic material obtainable and/or obtained by the process and its use are also described.
