Abstract: The present invention relates to a gas-phase process for the preparation of butadiene comprising (i) providing a gas stream G-1 comprising ethanol; (ii) contacting the gas stream G-1 comprising ethanol with a catalyst, thereby obtaining a gas stream G-2 comprising butadiene, wherein the catalyst comprises a zeolitic material having a framework structure comprising YO2, Y standing for one or more tetravalent elements, wherein at least a portion of Y comprised in the framework structure is isomorphously substituted by one or more elements X, as well as to a zeolitic material having a framework structure comprising YO2, Y standing for one or more tetravalent elements, wherein at least a portion of Y comprised in the framework structure is isomorphously substituted by one or more elements X, wherein the zeolitic material displays a specific X-ray powder diffraction pattern, and to its use.

Abstract: The present invention relates to a process for the production of a zeolitic material having a BEA-type framework structure comprising YO2 and X2O3, wherein said process comprises the steps of (1) preparing a mixture comprising one or more sources for YO2 and one or more sources for X2O3; (2) crystallizing the mixture obtained in step (1); (3) subjecting the zeolitic material having a BEA-type framework structure obtained in step (2) to an ion-exchange procedure with Cu; and (4) subjecting the Cu ion-exchanged zeolitic material obtained in step (3) to an ion-exchange procedure with Fe; wherein Y is a tetravalent element, and X is a trivalent element, wherein the mixture provided in step (1) and crystallized in step (2) further comprises seed crystals comprising one or more zeolitic materials having a BEA-type framework structure, and wherein the mixture provided in step (1) and crystallized in step (2) does not contain an organotemplate as a structure-directing agent, as well as to the zeolitic material having a BEA framework structure per se, and to its use, in particular in a method for the treatment of NOx by selective catalytic reduction (SCR).
