Abstract
Different kinds of catalysts are used in chemical processes to accelerate their reactions. One of the most important and well-known examples is the conversion of the pollutants generated by the combustion of fuel to non-toxic products. The significance, supply situation and the recovery processes of the precious metals used as catalysts — platinum, rhodium and palladium (hereafter referred to as PGM) — are described. The pyrometallurgical treatment of spent automotive exhaust catalysts is explained. The newly developed Degussa-process and its first results obtained are mentioned. The problems of logistics are discussed, and a brief view into the future of automotive exhaust catalysts is given.
