Abstract: This disclosure relates to a process for the dealumination of a zeolitic material including



(1) providing a zeolitic material having a tetravalent element and a trivalent element;
(2) providing an aqueous solution having a pH of less than 0.1;
(3) treating the zeolitic material with the aqueous solution; and

with an aqueous solution or with a solvent system, wherein the aqueous solution or the solvent system have a pH comprised in the range of from 4 to 10, wherein the pH of the aqueous solution or of the solvent system refers to the pH prior to contacting with the zeolitic material for treatment thereof. This disclosure also relates to a zeolitic material as obtained and/or obtainable according to said process.
