In the mid-1970’s the Environmental Protection Agency (EPA) set a higher regulatory standard on US automobiles’ exhaust. Catalytic converters were required as part of the exhaust system to convert the harmful compounds in the exhaust into harmless compounds. Usually, the converter is located between the engine and the muffler on the underside of the car.
Within the catalytic converter is a maze of honeycomb passageways. These small ceramic beads are coated with catalysts. This is where the chemical reaction takes place that makes the harmful pollutants less harmful. There are many passageways for the exhaust gases to flow because the purpose is the exposure of the most surface area of catalyst to the exhaust while minimizing the amount of expensive catalyst required. The two catalysts are the reduction catalyst and the oxidation catalyst. In the reduction catalyst, small amounts of platinum and rhodium metals convert the nitrogen oxide, which is a big contributor to smog, into nitrogen and oxygen. In the oxidation catalyst, there are small amounts of the precious metal palladium and platinum. Their purpose is to convert the dangerous hydrocarbons from the unburned gasoline to the safe exhaust of carbon dioxide and water.
State legislation requires that cars are inspected on a regular basis; this inspection includes a check for the absence of a converter or a malfunctioning one. A catalytic converter can fail if it becomes clogged or poisoned but there is no way of knowing when it is clogged. Fortunately, you can resell your scrap converter for money. The precious metals located within the converter can be extracted and recycled. Converter Guy will offer you the best price for your broken converter.
