Catalytic converters, essential components of vehicle exhaust systems, utilize a blend of precious metals, including platinum, palladium, and rhodium, to transform harmful pollutants into less toxic substances. The precise quantity of platinum within a converter varies depending on factors such as vehicle type, engine size, and the manufacturer’s specific design. Typically, a standard converter contains between 3 to 7 grams of platinum. This metal plays a crucial role in catalyzing the oxidation of carbon monoxide and unburnt hydrocarbons into carbon dioxide and water.
The presence of platinum, a highly effective catalyst, is vital for the efficient operation of emission control systems. Its ability to facilitate chemical reactions at relatively low temperatures makes it invaluable in reducing harmful emissions and meeting stringent environmental regulations. The demand for this precious metal in the automotive industry has contributed to its high value and has driven research into recycling methods for recovering platinum from spent converters. Historically, the amount of platinum used has fluctuated with both regulatory changes and advancements in catalytic converter technology.
