Abstract: Disclosed herein is a continuous process for preparing zeolitic material with a CHA-type framework structure comprising SiO2 and X2O3 and the zeolitic material so-obtained. The processes comprises (i) preparing a mixture comprising one or more sources of SiO2, one or more sources of X2O3, seed crystals, one or more tetraalkylammonium cation R5R6R7R8N+-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.

Abstract: The present invention relates to a specific continuous process for preparing a zeolitic material having a framework structure type selected from the group consisting of MFI, MEL, IMF, SVY, FER, SVR, and intergrowth structures of two or more thereof, preferably an MFI- and/or MEL-type framework structure, comprising Si, Ti, and O, and to a zeolitic material as obtainable and/or obtained according to said process. Further, the present invention relates to a process for preparing a molding, and to a molding obtainable and/or obtained according to said process. Yet further, the present invention relates to a use of said zeolitic material and molding.

Abstract: The present disclosure relates to a process for the preparation of a zeolitic material having a CHA-type framework structure comprising YO2 and X2O3, wherein the process comprises: (1) providing a mixture comprising one or more sources for YO2, one or more sources for X2O3, one or more tetraalkylammonium cation R1R2R3R4N+-containing compounds, and one or more tetraalkylammonium cation R5R6R7R8N+-containing compounds as structure directing agent; (2) crystallizing the mixture to obtain a zeolitic material having a CHA-type framework structure; wherein Y is a tetravalent element and X is a trivalent element, wherein R1, R2, R3, R5, R6, and R7 independently from one another stand for alkyl, wherein R4 stands for CnH2nOH with n=1 to 6, and wherein R8 stands for cycloalkyl.

Abstract: The present invention refers to a process for the preparation of a high surface area nanoparticulate alpha alumina.
