CATALYTIC CONVERTER GUIDE

WHAT ARE CATALYTIC CONVERTERS?

A catalytic converter is a device that uses a catalyst to convert three harmful compounds in car exhaust into harmless compounds. The catalysts are platinum and palladium, which are coated onto a ceramic honeycomb or beads that are housed in a muffler-like container attached to the exhaust pipe. The catalyst helps to convert carbon monoxide into carbon dioxide, and the hydrocarbons into carbon dioxide and water. It also converts the nitrogen oxides back into nitrogen and oxygen.

CATALYTIC CONVERTER VALUE

Palladium is an extremely rare, precious metal. It is 30 times more scarce than gold, and 15 times more rare than platinum. Palladium is one of three Platinum group metals. Platinum and rhodium are the other two. More than half of the Palladium mined is used in automotive catalytic converters which have been mandated is part of an effort to reduce harmful emissions. Worldwide vehicle production is estimated at 72 million, so you can see how the demand really adds up.

INDENTIFYING A CAT

When you have a full exhaust with a cat on it, please cut the cat off of the exhaust pipe, or manifold. Look inside one of the ends. If you can see straight through the cat with nothing in between the ends, you will have an exhaust or a muffler, and not a converter. If you instead see what looks to be a honeycomb, or a bead filling, you have a catalytic converter. Leave the filling inside. By removing the substrate from the case we will not be able to determine what type it is.

RECYCLE YOUR SCRAP CONVERTERS

Bring your catalytic converter to Michalak Battery & Core so Peter Michalak can identify what type of catalytic converter that you have. If you have any questions, just contact us at 207-797-8887, we'll be happy to answer your questions and give you an estimate on the value of your scrap converters. To receive the most accurate estimate, please have the serial number of the cat available. The make and model of the vehicle from which it came can be helpful as well.
