Abstract
Described is an organotemplate-free synthetic process for the production of a zeolitic material having an LEV-type framework structure comprising YOand optionally comprising XO, wherein said process comprises: (1) preparing a mixture comprising seed crystals and one or more sources for YO; and (2) crystallizing the mixture obtained in step (1); wherein Y is a tetravalent element, and X is a trivalent element, wherein the zeolitic material optionally comprises one or more alkali metals M, and wherein the seed crystals comprise zeolitic material having an LEV-type framework structure. Also described is a zeolitic material having an LEV-type framework structure obtainable by said process, as well as an organotemplate-free zeolitic material having an LEV-type framework structure comprising YOand optionally comprising XO, wherein Y is a tetravalent element, and X is a trivalent element, wherein the zeolitic material optionally comprises one or more alkali metals M, wherein said zeolitic material is non-calcined.
