Patent number: 10870583Abstract: A process for preparing a zeolitic material containing YO2 and X2O3, where Y and X represent a tetravalent element and a trivalent element, respectively, is described. The process includes (1) a step of preparing a mixture containing one or more structure directing agents, seed crystals, and a first zeolitic material containing YO2 and X2O3 and having FAU-, GIS-, MOR-, and/or LTA-type framework structures; and (2) a step of heating the mixture for obtaining a second zeolitic material containing YO2 and X2O3 and having a different framework structure than the first zeolitic material. The mixture prepared in (1) and heated in (2) contains 1000 wt % or less of H2O based on 100 wt % of YO2 in the framework structure of the first zeolitic material. A zeolitic material obtainable and/or obtained by the process and its use are also described.Type: GrantFiled: December 13, 2017Date of Patent: December 22, 2020Assignee: BASF SEInventors: Robert McGuire, Mathias Feyen, Ulrich Mueller, Xinhe Bao, Weiping Zhang, Dirk De Vos, Hermann Gies, Feng-Shou Xiao, Toshiyuki Yokoi, Ute Kolb, Bernd Marler, Chuan Shi, Xiulian Pan, Xiangju Meng, Stefan Maurer, Yu Dai, Yong Wang, Trees De Baerdemaeker
