Sibanye, Implats, BASF unite to ease palladium deficit
They’ve come up with a new catalyst that will replace between 20% and 50% of the metal in engine exhausts
German chemical group BASF, backed by two major SA platinum group metals (PGM) miners, has launched a new petrol engine antipollution device that uses less palladium.
The biggest talking point in the global PGM industry is the shortage of palladium and rhodium, the two metals used in petrol engine exhaust catalysts, their high prices, and when platinum will be used to substitute a portion of palladium.
The new catalyst will replace between 20% and 50% of the palladium in these devices, which use between 4g and 15g of palladium and rhodium depending on the size of the engine. Palladium is by far the biggest source of metal...
