A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds. The three harmful compounds are: 1  Hydrocarbons (in the form of unburned gasoline).2  Carbon monoxide (formed by the combustion of gasoline).itrogen oxides lead to smog and acid rain, and hydrocarbons produce smog. In a catalytic converter, the catalyst (in the form of platinum and palladium) is coated onto a ceramic honeycomb or ceramic beads that are housed in a muffler-like package attached to the exhaust pipe.
A 3-way catalytic converter is a sophisticated device used in the exhaust system of many modern petrol engine vehicles.It converts harmful gases in the engine exhaust to relatively harmless gases. three-way catalytic converter makes use of two catalysts to convert harmful gases to harmless gases. They are: 1  Reduction Catalyst and. 2  Oxidation Catalyst.
