Exhaust treatment system for a lean burn engine

Described herein is a process for producing a zeolitic material having an MWW framework structure containing YOand BO, in which Y stands for a tetravalent element. The process includes the steps of (i) preparing a mixture containing one or more sources for YO, one or more sources for BO, one or more organotemplates, and seed crystals, (ii) crystallizing the mixture obtained in (i) for obtaining a layered precursor of the MWW framework structure, and (iii) calcining the layered precursor obtained in (ii) for obtaining the zeolitic material having an MWW framework structure. Also disclosed herein are synthetic boron-containing zeolites obtain by the process and uses thereof.

A process for preparing a zeolitic material containing YOand XO, 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 YOand XOand 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 YOand XOand 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 HO based on 100 wt % of YOin the framework structure of the first zeolitic material. A zeolitic material obtainable and/or obtained by the process and its use are also described.
