Fuel or oil deposits build up on the surface of the converter. The engine could be burning oil but you wouldn't know it as long as the converter is functioning properly. But additives in the oil will eventually destroy the catalyst.

If the cat goes bad you will notice a large reduction in fuel economy, and it causes your vehicle to produce a lot more emissions. This may also cause your oxygen sensor to go bad and possibly your EGR valve as well.
Will bad ignition coils cause the catalytic converter to heat up and go bad?
Yes. If a coil is bad causing one or more cylinders to not fire, this allows raw unburned fuel to enter the catalytic converter, where it is burned. This can ruin a converter.
Can a bad catalyic converter cause high hydro carbons in a1988 jeep wrangler?
It can, you may also have misfire codes as well, having a bad cat causes all sorts of issues. There may be an underlying issue though because unburned fuel ( hydrocarbons ) is what causes a cat to go bad in the first place.
Can a catalytic converter cause the EGR valve to go bad?
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
