They convert nitrous oxides, unburnt fuel, and carbon monoxide to water, carbon dioxide and nitrogen.

To keep the car running - not at all. To minimize the amount of polluting exhaust - very.
because they do not help to reduce the amount of co2 in the atmosphere
The O2 sensors ( 2 of them ) nearest the engine are used to sense the amount of oxygen in the exhaust gasses and send a signal to the PCM that adjusts the air / fuel mixture for the engine . The O2 sensors ( 2 of them ) after the catalytic converters are called catalyst monitors and monitor how well the catalytic converters are performing
To reduce the amount of NOx, CO and HC that is expelled into the environment from a vehicle's exhaust. In other words, it helps keep the air we breathe a bit cleaner.
The oxygen sensors located before ( upstream ) of the catalytic converters are used to " sense " the amount of oxygen in the exhaust to adjust the air / fuel ratio for the engine
As far as the environment is concerned, yes. Catalytic converters are very important in regulating the amount of pollution your vehicle emits. As far as vehicle performance, removing a catalytic converter could increase horsepower and exhaust flow. Removing the converter can (and does on most) cause the computer to over-correct for the improper oxygen sensor readings. This over-correction usually causes a reduction in power, economy, and running performance. It is also highly illegal.
its useful because it reduces the amount of harmful gases but it does not get rid of it completely. it reduses the amount of NOx, CO and HC that is released in the air
When it erupts, it releases a large amount of carbon dioxide into the atmosphere, polluting it.
Seeing as this is in the car section....if this question is to see if its possible to extract the tiny amount of platinum from the ceramic lattice inside stolen catalytic converters, the answer is; you dont. Aside from destroying someone else's property by stealing the converter off their car, you will probably start a house fire trying to do it.
catalytic converter i think
only need to replace if it is clogged up or burned out.if a mechanic tells you it needs replacing at x amount of miles, he is just after your money. catalictic converters are very expensive to buy,so unless it is causing a problem,LEAVE IT ALONE
