All You Need To Know About Catalytic Converters

1. Article3: Globalrefininggroup.com All You Need To Know About Catalytic Converters Catalytic Converter is attached to the vehicles in order to convert the poisonous gases produced by internal combustion engines into less deadly fumes that are ozone-friendly. Most of the engines today from buses, trains, trucks, cars, lawnmowers etc. consist of Catalytic converters. Both Palladium and Platinum are precious metals which are brushed onto honeycomb-shaped matrix inside these devices. When exhaust flows, these metals convert the harmful gases into carbon dioxide and water. Typical car engines discharge fewer and less harmful gases into the atmosphere after conversion. Before conversion, an engine releases combustion gases such as Carbon monoxide, Nitrogen oxides hydrocarbons. Before emissions get to the catalytic chamber, the oxygen sensor records output from the engine. The vehicles can change the mix of oxygen in the engine so that stoichiometric point is maintained. This control ensures that enough oxygen is supplied to the converter so as to allow burning off of some of the chemicals (also known as oxidation process). Oxygen is the key to the whole catalysis process. Catalytic Converters consist of ceramic beads, or a network of honeycomb structures housed in a metal body. These plates are dipped in a metal catalyst such as Rhodium, Platinum or Palladium. These catalysts start a chain reaction with emissions delivered by exhaust system. Catalytic Converter reduces harmful emissions by converting them into safer compounds through the process of oxidation and reduction catalysis. These are two different types of chemical reactions that are used to convert harmful gases into harmless ones. Reduction catalysis occurs when Nitrogen oxide chemicals contact rhodium in the first portion of the converting process. The rhodium catalyst pulls the nitrogen from the molecule, leaving only oxygen as residual. The nitrogen atoms then attract each other, and form pairs to form Nitrogen. Oxidization is the second part of the catalytic process. Hydrocarbons and Carbon monoxide from the fuel burning process are subjected to platinum and palladium. This transforms the harmful chemicals into carbon monoxide, which then reacts with the oxygen to form Carbon dioxide. While the main purpose of a catalytic converter is to protect the environment and human health, the process is not without defect. Although Carbon dioxide is a far safer compound than the products that come out of the engine before the catalytic process, the release of Carbon dioxide into the atmosphere is a major cause for concern with regards to global warming. It is important to keep your catalytic system in good working order as part of the overall exhaust health of your car. Not only can a failed or dirty converter lose its effectiveness in reducing harmful emissions, it can reduce the performance of your car. Your catalytic converter may become clogged by gasoline additives in the fuel used to run your car; these additives may come from improperly de-leaded gas, or additives used in certain brands of gas to increase engine performance. In case the device does fail, catalytic converter recycling companies are always ready to accept it in exchange for money. You can pawn your scrap catalytic converters to these agencies to earn a dollar or two. For more information on recycling catalytic converters, visit Globalrefininggroup.com ABOUT THE AUTHOR
