Abstract (en)
[origin: WO2009153423A1] The invention relates to a method for the preparation of a cationic zeolite exchanged at least partially with one or more mono and/or multivalent cations. The method includes at least the following steps comprising: separate activation of a zeolite to be exchanged and an anhydrous salt under a dry inert gas stream, dissolution of the anhydrous salt in an anhydrous organic solvent, ionic exchange under a dry inert atmosphere, filtration and stripping with an anhydrous organic solvent, and calcination in the presence of oxygen under a dry gas stream. The invention also relates to the use of prepared zeolities for the separation or purification of hydrocarbon feeds.
