摘要
The present invention relates to an organotemplate-free synthetic process for the production of a zeolitic material having a BEA framework structure comprising YO 2 and optionally comprising X 2 O 3 , wherein said process comprises the steps of (1) preparing a mixture comprising seed crystals and at least one source for YO 2 ; and (2) crystallizing the mixture; wherein Y is a tetravalent element, and X is a trivalent element, wherein the zeolitic material optionally comprises at least one alkali metal M, wherein when the BEA framework additionally comprises X 2 O 3 , the mixture according to step (1) comprises at least one source for X 2 O 3 , and wherein the seed crystals comprise zeolitic material having a BEA framework structure, preferably zeolite Beta.
