The purpose of either the honeycomb or the beads is to slow the passage of exhaust gases through the converter.
What is a catalytic converter made of. The catalyst used in the converter is mostly a precious metal such as platinum palladium and rhodium. Platinum is used as a reduction catalyst and as an oxidation catalyst. Although platinum is a very active catalyst and widely used it is very expensive and not suitable for all applications.
The catalytic converters construction is as follows. The catalyst support or substrateFor automotive catalytic converters the core is usually a ceramic monolith that has a honeycomb structure commonly square not hexagonal. Prior to the mid 1980s the catalyst material was deposited on a packed bed of alumina pellets in early GM applications Metallic foil monoliths made of Kanthal.
Most modern models will be passageways of closely formed metal mesh. Picture a honeycomb made of metal and you will not be far off. Older models are full of ceramic beads instead of the honeycomb design.
The purpose of either the honeycomb or the beads is to slow the passage of exhaust gases through the converter. Catalytic converters are small chambers where those unburned substances are combined with oxygen and burned more completely. The exhaust that flows away from the catalytic converter and out the tailpipe is much cleaner than what came out of the engine.
In a catalytic converter the catalysts job is to speed up the removal of pollution. The catalyst is made from platinum or a similar platinum-like metal such as palladium or rhodium. A catalytic converter is a large metal box bolted to the underside of your car that has two pipes coming out of it.
The catalyst in your converter is typically made of palladium rhodium and platinum. These rare metals coat a ceramic interior which is typically in a honeycomb or bead shape and converts harmful gases into less harmful emissions. Typically your catalytic converter converts approximately 90 of emissions but there are a number of factors that can increase or decrease the efficiency.
Exhaust has a lot to do with performance. Catbacks Mufflers and resonators get all the attention but the Catalytic Converter is super cool too. I fumble my way through a complicated chemical extractionHelp me make videos by donating here.
There are three primary metals used inside of catalytic converters as well as other materials. Platinum is the most widely used. You could also find palladium rhodium cerium manganese and nickel.
Two of the three rare earth metals used in catalytic converters are worth more per ounce than gold. Palladium spot prices are currently more than 2300 gold is about 1900 a 20 percent increase. Platinum rhodium and palladium are some of the elements known as platinum-group metals otherwise known as PGMs.
Depending on the age and type of vehicle the PGMs in a catalytic converter can be. The Shape of the Comb There are a couple of different shapes the honeycomb can be but the two most common are a honeycomb shape and the other is a foilwire which is shaped like a fingerprint. The foil cats are always worth much less than a honeycomb cat.
Pre Cats Usually much smaller and have less good material inside. Now that you know the real deal about catalytic converters its time to take a look at the perks of catalytic converter recycling. Perks of Catalytic Converter Recycling Heres the deal.
Whenever anything is mined from the earth it can have a major negative impact on our environment. The catalytic converter uses precious metals and high heat to oxidize and reduce harmful emissions converting them into safer compounds like H2O CO2 nitrogen N2. The catalytic converter consists of a special catalyst.
It is made of platinum and palladium which carries out the chemical reactions. Construction of Catalytic Converter. The catalytic converter housing consists of a honeycomb core from inside.
A catalytic converter is simply a stainless steel box thats attached to the muffler. The box contains beads and its coated with catalysts on the inside usually with compounds such as alumina ceria. The compounds can be combined with the following materials.
Catalytic converters help control exhaust emission in vehicles. You wont know its gone until you start your car. I started my car and there was a roaring noise said Alyssa Wurzberg.
