Abstract
A process for the incineration of activated coal-supported PGM catalysts, the process comprising a joint incineration of a multilayer arrangement, wherein the multilayer arrangement includes (i) a top layer of particulate activated coal-supported PGM catalyst, (ii) a layer of coarse charcoal located beneath said top layer and, optionally, (iii) a layer of particulate coke located beneath the charcoal layer, and wherein an upward flow of oxidizing gas is homogeneously passed through said multilayer arrangement during the incineration.
