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 continuous process for the preparation of a zeolitic material comprising SiO2 in its framework structure, said process comprising (i) continuously preparing a mixture comprising one or more solvents, one or more structure directing agents, and one or more sources of SiO2; (ii) continuously feeding the mixture prepared in (i) into one or more continuous flow reactors; and (iii) heating the mixture in the one or more continuous flow reactors for continuously obtaining a zeolitic material comprising SiO2 in its framework structure; wherein the mixture contained in the one or more continuous flow reactors is subject to a pulsatile flow regime. The present invention also relates to a zeolitic material as obtainable and/or obtained according to said process and the use of the zeolite material as a molecular sieve, as an adsorbent, for ion-exchange, or as a catalyst and/or as a catalyst support.

Abstract: Process for precipitating a mixed hydroxide of TM wherein TM comprises Ni and at least one of Co and Mn and, optionally, Al, Mg, Zr or Ti, from an aqueous solution of salts of such transition metals or of Al or of Mg, wherein such process is carried out in a stirred vessel and comprises the step of introducing an aqueous solution of alkali metal hydroxide and an aqueous solution of transition metal salts through at least two inlets into said stirred vessel wherein the distance of the locations of introduction of salts of TM and of alkali metal hydroxide is equal or less than 6 times the hydraulic diameter of the tip of the inlet pipe of the alkali metal hydroxide.
