© 2020 Trans Tech Publications Ltd, Switzerland.The team of authors described a solution to the problem of developing a fundamentally new technology for the industrial processing of spent diesel automotive catalysts containing platinum group metals (PGM) and SiC carrier, which has such advantages as carrying out a full processing cycle in one hardware module. The processing of SiC catalyst is extremely difficult by pyrometallurgical methods, but proposed technology is based on the electrochlorination method. The scientific novelty of the proposed method lies in the superposition of two independent electrolysis processes in direct and alternating, with varying frequency, currents under conditions of forced, continuous and complete recondensation of the electrolyte. The study of the diesel catalysts processing by the electrochlorination method have carried out.
