As it is known, automobiles make our travelling convenient and make our lives
easier. However, every coin has its two sides. The pollution produced by
automobiles to people and nature is undeniable. Gases from exhausts cause
serious damage to both human health and the environment. It causes air
pollution. Therefore, catalytic converters have been used in automobile for
approximately 45 years to largely decrease these gases released into the
atmosphere.
A catalytic converter uses a chamber called a catalyst to change the harmful compounds from an engine’s emissions into safe gases, like steam. It works to split up the pollution molecules in the gases that a car produces before they are released into the air.
Installed on the underside of a vehicle , the catalytic converter looks like a metal box. There are two pipes coming out of it. The convertor utilizes these two pipes and the catalyst during the process of making the emission gases safe to be exhausted.
Gases are brought in from the input pipe connected to the engine of a vehicle.
These are blown over the catalyst, where chemical reaction happens as a result,
it breaks apart the pollutants. The less-harmful gases now travel through the
second pipe, or the “output,” that is connected to a car’s tailpipe.
In catalytic converters connected to the
exhaust outlet pipe of cars, the platinum group metals convert carbon monoxide
gas (CO), hydrocarbons (HC) and nitrogen oxides (NOx) released into
the air into less harmful carbon dioxide (CO2) and water vapor.
Catalytic converters contain platinum, palladium and rhodium precious metals
from platinum group metals as catalysts.
It provides the breakdown of platinum and palladium hydrocarbons into water
vapor and carbon dioxide. Rhodium converts nitrogen oxides and carbon monoxide
into nitrogen and carbon dioxide.
As there are many types of car catalyst, the amount of PGM’s varies
significantly. PGM here satands for platinum group metal. The fast and accurate
testing method is required for the PGM’s content evaluation. Handheld or
portable XRF analyzer provides precise and fast catalytic converters analysis
for simple sorting and price evaluation. Usually, a concentration of PGM’s in a
car catalyst is much higher, than in ores.
Typically there are 3 to 7 grams of platinum in a standard catalytic converter.
A standard converter also contains 2 to 7 grams of palladium and 1 to 2 grams
of rhodium.
A recycler will pay between $60 and $260 for a catalytic converter, with some
going for $800 to $1,500 if they come from hybrid vehicles. Keep in mind that
if your catalytic converter gets stolen, it could cost around $2,000 to replace
it.
As we already know, three-way catalytic converter is the most important external
purification device installed in the automobile exhaust system. The catalyst in
the three-way catalytic converter can catalyze the oxidation-reduction reaction
of carbon monoxide, nitrogen-hydrogen compounds and nitrogen-oxygen compounds
in the automobile exhaust, reducing automobile exhaust pollution, which is an
essential part of the automotive industry. Because the three-way catalyst
contains platinum (Pt), palladium (Pd), rhodium (Rh) and other rare and
precious metals, these metals can be recycled and reused and are conducive to
environmental protection, so the recycling of the three-way catalyst and the
identification of true and false need to be fast and effective analysis and
detection methods.
With Terra900 Handheld XRF spectrometers, it takes just seconds to give the
result comparing with hours or days as in a laboratory. Together with simple
operation training and easy sample preparation, they are ideal and affordable
solution for the daily business for quality control and price evaluation during
catalyst’s dealing.
Following is the testing data for a catalyst standard to verify the testing
stability of handheld XRF analyzer with a catalyst calibration.
AXR Scientific Terra900 series handheld XRF analyzers can be equipped with car
catalyst calibration and provide fast, on-site analysis of spent car catalysts,
with minimum sample preparation required. It can easily and reliably be used in
the recycling and refining process of automotive catalytic converters to determine
the concentration of platinum, palladium and rhodium. Besides, it can fast
analyze other metal elements for the metal scrap from recycled automobiles to
do scrap sorting job easily.
