What Materials are Used in Catalytic Converters? 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.

California Catalytic Converter Laws and Regulations Location: The catalytic converter exterior is usually made of stainless steel. The CAT looks very similar to a muffler except it contains a catalyst substrate within and is normally located in the exhaust system before the muffler and after the exhaust manifold.

- Three-Way Catalysts (TWC) are the main technology used to control emissions from petrol engines. The catalyst uses a ceramic or metallic substrate with an active coating incorporating alumina, ceria and other oxides and combinations of the precious metals-platinum, palladium and rhodium.hree-way catalysts operate in a closed-loop system including a lambda or oxygen sensor to regulate the air:fuel ratio on petrol engines.

- The substrates are the backbone of the converter. This is where the proprietary mix of precious metal(s) and the washcoat formulated to store O2 allow the conversion process to take place. Converters are available in single-or multiple-substrate designs.

- Introduction to Catalytic Converters. A catalytic converter is a vehicle emissions control device that is used to convert toxic byproducts of combustion (occurring in the exhaust of an internal combustion engine) to less toxic substances by performing catalysed chemical reactions.

What does a catalytic converter do?   The catalyst in a catalytic converter causes unburned hydrocarbons  to oxidize. To do so, oxygen must be present in the exhaust  mixture. If an engine is running well, there isn't really much for  the catalytic converter to do.

How Catalytic Converters Work This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O 2 2. There are two main types of structures used in catalytic converters -- honeycomb and ceramic beads.or example: or. Ceramic honeycomb catalyst structure. The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst.

Catalytic converter These three reactions occur most efficiently when the catalytic converter receives exhaust from an engine running slightly above the stoichiometric point. For gasoline combustion, this ratio is between 14.6 and 14.8 parts air to one part fuel, by weight.

Catalytic Converters A catalytic converter is a simple device that uses basic redox reactions to reduce the pollutants a car makes. It converts around 98% of the harmful fumes produced by a car engine into less harmful gases. It is composed of a metal housing with a ceramic honeycomb-like interior with insulating layers.

- How a catalytic converter works. Before catalytic converters were developed, waste gases made by a car engine blew straight down the exhaust tailpipe and into the atmosphere. Molecules of polluting gases are pumped from the engine past the honeycomb catalyst, made from platinum, palladium, or rhodium.

- A catalyst is a substance that will change the rate of a reaction. A catalyst is often used to make a reaction go faster. The catalyst does not take part in the reaction as a reactant. It is not changed by the reaction or used up during the reaction. It is still there in the same form when the reaction is complete. A catalyst can be a transition metal, a transition metal oxide (see the uses of transition metals) or an enzyme. An exception is aluminium oxide, used for the cracking of hydrocarbons. A substance which works well as a catalyst for one reaction might not work well as a catalyst for a different reaction.

Catalytic converter The washcoat. A washcoat is a carrier for the catalytic materials and is used to disperse the materials over a large surface area. Aluminum oxide, titanium dioxide, silicon dioxide, or a mixture of silica and alumina can be used. The catalytic materials are suspended in the washcoat prior to applying to the core.

High Flow Catalytic Converters: How They Increase Engine Performance and Why You Should Get One Waste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides. It is the catalytic converter’s job to reduce these harmful emissions as much as possible in order to protect the air we breathe.The way that the catalytic converter functions is simple. It forces the exhaust gasses to come in contact with a chemical catalyst, in this case the metals platinum or palladium.The catalyst causes the gasses to quickly degrade into less harmful substances, like carbon dioxide and water.aste gasses from the motor contain harmful smog chemicals such as hydrocarbons, carbon monoxide and nitrogen oxides.

Three-way catalytic converter - how does it work? In the modern three-way catalytic converter, uncombusted fuel residues are oxidized with oxygen to produce carbon dioxide and water, nitrogen oxides are converted to ubiquitous nitrogen, and toxic carbon monoxide is oxidized with oxygen to carbon dioxide.he development of the first three-way catalytic converter in 1979/80 marks a milestone in exhaust gas technology. This device was able to catalyze the conversion of the three main pollutants (unburned hydrocarbons, carbon monoxide and nitrogen oxides) simultaneously.

Scrap Catalytic Converter Recycling Scrap catalytic converters contain some of the most expensive metals on the planet-metals that never wear out, even if the converter stops functioning and must be junked. Since 1975, every vehicle sold in the US and Canada is literally a platinum mine on wheels that can eventually be replaced.
