Abstract:
The present invention relates to a process for the production of a pillared silicate comprising: (i) providing a layered silicate; (ii)interlayer expanding the layered silicate provided in step (i) comprising a step of treating the layered silicate with one or more swelling agents; (iii)treating the interlayer expanded silicate obtained in step (ii) with one or more hydrolyzable silicon containing compounds; (iv)treating the interlayer expanded compound obtained in step (iii) with an aqueous solution to obtain a pillared silicate; (v)removing at least a portion of the one or more swelling agents from the pillared silicate obtained in step (iv); (vi) impregnating the pillared silicate obtained in step (v) with one or more elements selected from the group consisting of Fe, Ru, Ir, and combinations of two or more thereof, as well as to a pillared silicate optionally obtainable from said process and its use, in particular in a process for the production of one or more olefins according to the invention.
Abstract:
Provided is a process for the preparation of a zeolitic material having a BEA framework structure comprising the steps of: (i) providing one or more zeolitic materials having a BEA framework structure, wherein the BEA framework structure comprises Y0 2 and X 2 O 3 , wherein Y is a tetravalent element, and X is a trivalent element; (ii) subjecting the one or more zeolitic materials provided in step (i) to a procedure for removing at least a portion of X, preferably tetrahedrally coordinated X, from the BEA framework structure; wherein the Y:X molar ratios of the one or more zeolitic materials provided in step (i) are respectively comprised in the range of from 1 to 50.
