Pantone simply!

[jean63]

For nicky...

I have somewhere an article on the discovery by American scientists in several big cities of the USA, of high concentration levels in the air of the cities, of metals contained in the catalytic converters (easy to locate apparently).
It is quite recent, moreover ...; I think I will find it because I had to keep it in my "clean energies" file.
These metals would therefore be expelled from the Catalan pots. under certain conditions ........

I'm trying to find this article.

Indeed, seen like that ....
It's stupid, lead emissions in France had dropped by a factor of 12 between 1990 and 2002 and now we are rejecting other heavy metals in quantities that we now know to be problematic!

Well, it's not just the Americans who work on it, French scientists have also been studying this for a few years:

A study by researchers from the Laboratory of glaciology and environmental physics (UJF-CNRS) carried out jointly with Italian scientists from the University of Venice shows that catalytic converters, reputed to be ecological, are probably the source of pollution worrying about heavy metals! These pots release increasing amounts of platinum, rhodium or palladium into the atmosphere. Researchers have not yet been able to measure the risk to human health of this pollution caused by an anti-pollution device.

However, I did not hear or read that they published the results of their work ...

Bonsoir.
You are right to mention this subject that I know well since I was already interested in it a year ago.
I have applied for a patent with the aim (among other things) of reducing this source of pollution.
The document will be available around July.
I will keep you posted.
See you soon.

A patent on a catalysis technique? A manufacturing process different from ceramic monoliths?

Interesting in any case, it's nice to keep us informed.

Thank you ex-oceano,

it confirms what I had read but I had a doubt ..... it's incredible but TRUE.

Hello,
I want to remind you that the panton reactor is not a simple exchanger, if we wanted to make a heat exchanger we would proceed with a long concentric tube on the entire length of the car

I hope so but a better exchanger is mentioned because of a remark on the higher efficiency of the pantone on an engine that heats up a lot, the shortcut pantone = exchanger nobody has done it so far;)
