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.
by Colin Smith. A new catalytic converter that could cut fuel consumption and manufacturing costs has been designed by a scientist from Imperial College London. A catalytic converter is the component in a vehicleâs exhaust system that eliminates some harmful emissions.Tests suggest that the new prototype could reduce fuel consumption in a standard vehicle by up to three per cent.y Colin Smith.
