They make up the majority of catalysts used in the automotive industry today. The catalyst consists of a metal casing that protects a ceramic core liner with a honeycomb structure. The catalyst liner is coated with a refractory oxidation layer (Washcoat) of inorganic base metal oxides and the precious metals Platinum, Palladium and Rhodium. The coating creates a chemical reaction that converts health-threatening toxins into safer chemical compounds.
The ceramic catalyst undergoes a disintegration process where the catalyst shell is separated from the liner by hydraulic shears. The liner is then crushed and ground into a homogeneous powder. The grinding takes place in a mill with a capacity of 500 kg of material. Smaller mills can be used for the analysis of smaller numbers of catalysts (1-5 pieces). The entire material separation and transport area is exhausted in order to capture all material particles and avoid losses, as well as to protect health and the environment. The resulting analysis of the ground samples is then determined in our laboratory.
