Estimating the term…
The present invention relates to a rare earth element containing zeolitic material having a framework structure selected from the group consisting of AEI, AFT, AFV, AFX, AVL, CHA, EMT, GME, KFI, LEV, LTN, and SFW, including mixtures of two or more thereof, the framework structure of the zeolitic material comprising SiO2 and X2O3, wherein X stands for a trivalent element, wherein the zeolitic material displays an SiO2:X2O3 molar ratio in the range of from 2 to 20, and wherein the zeolitic material contains one or more rare earth elements as counter-ions at the ion exchange sites of the framework structure. Furthermore, the present invention relates to a process for the production of the inventive rare earth element containing zeolitic material as well as to the use of the inventive rare earth element containing zeolitic material as such and as obtainable and/or obtained according to the inventive process.
A zeolitic material, having a framework structure selected from the group consisting of AEI, AFT, AFV, AFX, AVL, CHA, EMT, GME, KFI, LEV, LTN, SFW, and mixtures of two or more thereof, the framework structure comprising SiO2 and X2O3, wherein X is a trivalent element,
A process of producing a zeolitic material having a framework structure selected from the group consisting of AEI, AFT, AFV, AFX, AVL, CHA, EMT, GME, KFI, LEV, LTN, SFW, and mixtures of two or more thereof, the framework structure comprising SiO2 and X2O3, wherein X is a trivalent element, the process comprising:
