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.
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. If the engine is in need of a tune-up, the catalytic converter may get quite a workout and in the process it can get very hot.Also, deposits can build up on a catalytic converter, making it useless.f an engine is running well, there isn't really much for the catalytic converter to do.
