摘要： Damaged or spent catalytic converters of the type having a metallic container for foil-shaped carriers of washcoats for catalysts of noble metal are recycled by admitting them into an impact pulverizer which forms a mixture of randomly distributed particles belonging to a first fraction containing dust-like particles of washcoats and catalyst or to a second fraction containing nonmagnetizable particles of containers and magnetizable particles of carriers. A high percentage of the first fraction is withdrawn from the pulverizer with an air stream which also entrains a percentage of the second fraction, primarily particles of carriers; such particles of carriers are separated from the stream in a first step and the particles of the first fraction are thereupon separated from the stream for admission into a collecting receptacle. The remainders of the first and second fractions are evacuated from the pulverizer along a second path, such as by gravity flow, and the mixture of first and second fractions is thereupon classified by pneumatically conveying the remaining particles of the first fraction into the collecting receptacle and by magnetically separating the remaining particles of the carriers from the particles of the containers.
