Catalytic Converters

Catalytic converters are an integral part of converting much of the pollution that comes out of a car’s exhaust. (2) Since the 1970´s, almost every car has a catalytic converter integrated to reduce harmful emissions. I will explain the chemistry behind the catalytic converter and how it works.

To solve the huge problem dealing with cars polluting a city, the cities, states and federal governments make clean-air laws to restrict the amount of pollution that cars can produce. Over many years, car producers have found ways to reduce the pollution and one was the catalytic converter, which was invented in 1975. The catalytic converter, converts harmful pollutants into less harmful ones, before they even leave the car. Eugene Houdry invented the catalytic converter in 1973 where he then patented it. The catalytic converters were further more developed by two engineers called John Mooney and Carl Keith. The catalytic converter is placed under the front seat by most carmakers. (See photo)

)

Cars produce a lot of harmful emissions, but the main ones are: carbon monoxide which is a piousness gas, hydrocarbons which is mostly produced by evaporated, unburned fuel and nitrogen oxides, which cause irritation to human mucus membranes.
But how does a catalytic converter help reduce the emissions? To answer this question, we first need to look into what a catalyst is. A catalyst is a substance, which accelerates a chemical reaction without itself being affected. (3) The human body also contains catalysts, which are called enzymes. These accelerate the reaction of biochemical reactions in the human body. In a catalytic converter, there are two types of catalysts inside. The first one is the reduction catalyst and the other is the oxidation catalyst. Both of the catalysts consist of a ceramic structure. The reduction catalyst is the first step of the catalytic converter. It uses platinum and rhodium to reduce the NOx emissions.

    In this day and age of constant threat to our environment, there are various ways of reducing air pollution and energy consumption is being explored. Cars whose emissions are part of the factors that contribute to air pollution, are being modified to be more environment-friendly. However, these cars are expensive to produce. Majority of the population, especially here in the Philippines, cannot afford a highly energy efficient and environment friendly vehicle. Also, problems like the disposal of tons of electric car batteries will arise.…

    Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes, and wires. But Its basic operating principle is that combustion, or the controlled, steady burning of air and fuel in the combustion chamber, creates power that forces components within the engine to move with great speed and force. The process of an internal combustion engine can be explained in four stages. The four stages that need to take place in order for an internal combustion engine to work are called the Intake stroke, compression stroke, power stroke, and the exhaust stroke.…

    Different pollutants released from the vehicles would cause different impacts to the human body. The first one is Nitrogen oxides (NOx). When the fuels are burning at a very high temperature combined with the electric sparks in the vehicles causing the nitrogen and oxygen in the atmosphere combined together but then the formation of nitrogen oxide will react with the oxygen to form nitrogen dioxide(NO2) rapidly. If people inhaled a low level of NO2, the gas will irritate your eyes, nose, throat, and lungs, possibly causing you to cough, tiredness, and nausea since NO2 is an acidic gas. Also, low level of nitrogen dioxide may trigger asthma and causing the formation of fluid inside the lung 1 or 2 days after inhaled. If people inhaled a high level of NO2, the gas will cause spasms, rapid burning, the tissues in the throat and upper respiratory tract swollen, the fluid also form in the lungs and the oxygenation of the body cell reduced, even may lead to die.…

    Catalytic Solutions, Inc. (CSI) was founded in Santa Barbara, California, in 1996 by Steve Golden and Bill Anderson. Being a young company, CSI is still in a “pre-profit” stage of operation that is why its performance measurement and incentive systems are primarily based on nonfinancial. For the first few years, CSI had developed innovative catalytic converters to the automobile market, which are used to reduce the pollution caused by combustion engine. CSI owns a technology that allows it to produce better performance and cheaper catalytic converters than competitors did.…

    These fumes and chemicals usually originate from factories, automobiles, dust, pollen, and fungus such as mold. A gas known as ozone plays a major part in air pollution. Smog is created when ozone contaminates the air. Another hazardous gas is carbon dioxide, which is a greenhouse gas. This toxic vapor is responsible for global warming. Although many things release carbon dioxide when breathing, it is considered a contaminant (pollutant) when it is linked with automobiles, aircrafts, factories, and other human related doings that use and burn fossil fuels such as gasoline and natural gas. The reason air pollution is dangerous is because it is possible for it to be poisonous. Inhaling these toxins forming in the air can lead to heart or lung disease. Also, air from mold and dust insides many buildings are also likely to affect your…

    Most of the people in the world still support the perception about cars being one of the main air pollutants on the planet. General Motors promoted their Fuel Cell technology under the Chevrolet division with the “Chevy Equinox” car on the Smithsonian magazine in September 2008, when posting an advertisement that presented their newest technology for environment friendly cars, the Equinox fuel cell. The magazine is a lifestyle magazine that is designated to people who love to read about nature, culture, science, and travel. The advertisement, that consist from a car that is inside of a big field of green grass and flowers and a text box that explains the technology of the Fuel Cell, is trying to emphasis the difference between the new technology that the car company is offering in the “Chevy Equinox” to the regular technology that is consider less environmentally friendly. The car industry, as I mentioned above, is considered one of the main reason for air pollution around the planet. The way General Motors id focusing on keeping the environment as clean as possible and prevent air pollution can be portrayed as a surprise. The methods of advertising the car companies used are trying to fix the population perception about car pollution and persuade readers that the newest technology of the “Chevy Equinox”, the Equinox fuel cell, is concerned about the environment and the air pollution causing by cars.…

    Clean coal technology is a term used to describe technologies being developed that aim to reduce the environmental impact of coal energy generation. It implies that it is possible to make coal a fuel source that is free of (or very low in) carbon dioxide emissions and other pollutant emissions. Some of the techniques that would be used to accomplish this include chemically washing minerals and impurities from the coal, gasification (see also IGCC), treating the flue gases with steam to remove sulfur dioxide, carbon capture and storage technologies to capture the carbon dioxide from the flue gas and dewatering lower rank coals (brown coals) to improve the calorific value, and thus the efficiency of the conversion intoelectricity.…
