Abstract

The invention relates to a method for doping zeolites with metals, said method comprising the following steps: i) a dry mixture is produced from a) a zeolite, b) a compound of a catalytically active metal, and c) a solid urea or a urea derivative; ii) the mixture is intimately ground; iii) the mixture is heated; and iv) the mixture is cooled to room temperature and the metal-doped zeoolite obtained. The invention also relates to a composition for doping zeolites with metals.
