METHOD FOR THE PRODUCTION OF A ZEOLITE MATERIAL LOADED WITH IRON, COPPER, AND/OR SILVER

摘要

The invention relates to a method for producing a zeolite material that is loaded with iron, copper, and/or silver. The aim of the invention is to create a method which allows relatively large quantities of iron, copper, and/or silver to be introduced into a zeolite material. Said aim is achieved by a method comprising the following steps: a) a zeolite material that has an MFI or BEA type of structure is suspended in an aqueous solution containing iron ions, copper ions, and/or silver ions as well as ammonium ions; b) the zeolite material is left in the solution until the zeolite material is charged with a certain number of metal ions; c) the charged zeolite material is separated from the solution; d) the charged zeolite material is optionally calcined at a temperature at which ammonium ions are decomposed into NH₃ and H⁺; e) the metal ions introduced into the zeolite material are optionally converted into the metallic form or an oxidic form.
