Question on decanned converters

it has been a while since I delt with converters0but I know that a couple of years ago they were paying just $12# for honey comb and dust because like you said they couldn't tell what it came from until after process.
while they would pay 150 for a whole jeep or chysler cat.

there are a couple of cat buyers here that should be able to help you

If you purchased decanned cats, you will have no clue what the yield will be until you ball mill and assay. Otherwise it's a crap shoot.

Some people decan because whoever they dealt with in the past trusted them, and was alright with the yield, etc. If that is the case, if they used to sell to someone else but no longer do, then ask to speak with that person so you can ask questions like "Did they deal with you honestly" or "who was buying your catalytic material" and "why are you not doing it anymore". Answers to questions like these can help you decide if you should be purchasing cats in your particular market.

I know where I live, competition is so tight that you are lucky to find any cats in any quantity. They are all being accumulated and sent out of state to be processed.

Sometimes the person selling the cats sells them decanned because they know you are not going to be able to judge how much PGMs there are, approx. They may be hoping that you overpay because of the work involved in decanning.

Ask the question "how long have you been scrapping cats" if they have for any length of time, they already know better than to decan. Then you ask the question "you know already you get less for decanned cats, why did you decan them?". I think you get the picture.

If he's new, he probably didn't have a clue.

I thought this would probably be a good thread to post this information, this is yield data on different types of cats, with the pictures and what type of vehicle they come from.

More than likely aftermarket or low grade material. Especially if it was decanned intentionally. Most reputable/large buyers have stopped buying loose material from the public for this reason.

I decan all mine and have no problem reselling it, especially with platinum as high as it is and headed higher. I have 700 pounds of honeycomb and 100 pounds of foil i have extracted. Its best if you can extract the bricks intact, buyers like the look of intact bricks better than crushed chunks. Sometimes i decan them and sometimes i just rod them out, it really just depends on how i am feeling about it that day. If you dont want to decan i would recommend cutting them so that you have steel sticking 1/2" away from the edge of the bricks, that way it costs less to ship and is still recognizable as a cat.

The other thing you can do, so the buyer knows exactly what they are getting is to decan your cats, mill them then pull a correct representative sample to be assayed. You will know the exact value of your material dependent upon how homogenous your mix is. Then there is no playing around, you will get more for your cats than you otherwise would.
