Catalytic car exhaust converters are used to reduce harmful emissions into the atmosphere. The emissions contain carbon monoxide (CO) — a toxic gas without color and odor, hydrocarbonates (HxCy) — volatile organic compounds resulting from incomplete combustion of fuel which leads to smog, as well as nitrogen oxides (NOx), which causes smog and acid rain. The automotive catalysts convert these harmful substances to harmless carbon dioxide, water and nitrogen.
Because of precious metals, which are used in catalysts they should be recycled in order to extract MPG from them. To do this, the cellular ceramic block is extracted from the metal case, crushed and subjected to affinity refining.
Due to the large number of different types of automotive catalysts, the content of PGM in them varies significantly. Therefore, a quick and accurate analysis of the catalysts on the concentration of PGM is extremely important and allows a reliable estimating of the cost of the catalyst. The use of XRF analysis for this purpose allows to solve this problem most effectively.
For accurate and reliable express analysis of the contents of platinum (Pt), palladium (Pd) and rhodium (Rh) in waste automotive catalytic converters, Elvatech offers hand-held, mobile and benchtop X-ray fluorescence spectrometers and analyzers
