HIGH-TEMPERATURE PROCESSING AND RECOVERY OF AUTOCATALYSTS

Popis výsledku v původním jazyce

This paper presents the results from an experimental study of the thermal method applied for obtaining platinum-group metals (PGMs) by melting used autocatalysts in an 80 kVA plasma reactor, using suitable fluxes and a reducing agent. As the collector of noble metals, grey cast iron was used during the melting. The melt products were the alloy, inert vitrified slag, syngas and fly ash. In the alloy, when melting the catalyser based on cordierite. there was 99.27 % PGMs and 99.00 % in the case of Cr/Ni-strip catalysts. The loss of PGMs in the slag during the melting of cordierite catalysts was 0.34 % and for Cr/Ni catalysts, it was 0.26 %. A chemical analysis of the ash confirmed that in addition to the mechanically removed CaO, SiO2, MgO, Al2O3, it also contained condensed vapours of Fe+PGMs. During the melting of the cordierite catalyst, the ash contained 0.40 % of the refined metals, while 0.74 % was the figure for the Cr/Ni-strip catalyst. The synthesis gas from the process had a very low heating value (0.16 MJ m(-3) or 0.24 MJ m(-3)).
