Radiotracer methods have been developed to quantify the amount of platinum and rhodium deposited on automotive catalytic converters as a function of production conditions. In particular, this study determined the effects of selective adsorption and evaporation processes on the aqueous impregnation of ...
The catalyst is a platinum (Pt) metal on an alumina (Al2O3) base. While catalysts are never consumed in chemical reactions, they can be fouled, making them less effective over time. The series of reactors used in Catalytic Reforming are therefore designed to be disconnected, and swiveled ...
