Abstract

The present invention relates to a process for the preparation of a zeolitic material SiO2 and X2O3 in its framework structure, wherein X stands for a trivalent element, wherein said process comprises interzeolitic conversion of a first zeolitic material comprising SiO2 and X2O3 in its framework structure, wherein the first zeolitic material has an FER-, TON-, MTT-, BEA-, MEL-, MWW-, MFS-, and/or MFI-type framework structure to a second zeolitic material comprising SiO2 and X2O3 in its framework structure, wherein the second zeolitic material obtained in (2) has a different type of framework structure than the first zeolitic material. Furthermore, the present invention relates to a zeolitic material per se as obtainable and/or obtained according to the inventive process and to its use, in particular as a molecular sieve, as an adsorbent, for ion-exchange, or as a catalyst and/or as a catalyst support.
