Title: IRON- AND COPPER-CONTAINING ZEOLITE BETA FROM ORGANOTEMPLATE-FREE SYNTHESIS AND USE THEREOF IN THE SELECTIVE CATALYTIC REDUCTION OF NOX
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, one or more sources for X2O3, and seed crystals comprising one or more zeolitic materials having a BEA-type framework structure; (2) crystallizing the mixture obtained in step (1); and (3) subjecting the zeolitic material having a BEA-type framework structure obtained in step (2) to an ion-exchange procedure with Cu and/or Fe; wherein Y is a tetravalent element, and X is a trivaient element, wherein the mixture provided in step (1) and crystallized in step (2) does not contain an organotemplate as structure-directing agent, and wherein the total amount of Cu and/or Fe in the ion-exchanged material obtained in step (3) ranges from 0.1 to 25 wt.-% calculated as Fe2O3 and CuO, as well as to a zeolitic material having a BEA-type framework structure which may be obtained according to said process, and to a method for the treatment of NOx by selective catalytic reduction (SCR) using said zeolitic material.
