Recently, researchers at the University of California, Santa Barbara used a simple low-temperature catalytic method to convert plastics such as polyethylene into high-value alkyl aromatic molecules, opening up a new way to recycle plastic waste
.
The researchers explained that conventional methods require 500°C to 1,000°C to break down the polyolefin chains into small pieces and then allow them to recombine into a product consisting of a mixture of gas, liquid and coke
.
In addition, the new method does not require the addition of solvent or hydrogen, and requires only platinum on an alumina catalyst to perform a tandem reaction that both breaks the tough carbon-carbon bonds and rearranges the molecular backbone of the polymer to form high Valuable alkyl aromatic molecules that are used in the manufacture of solvents, paints, lubricants, cleaners, pharmaceuticals, and more
.
Plastics can be seen everywhere in our daily life.
The annual output value of plastics produced worldwide is about 200 billion US dollars, but its recycling and reuse is a big problem
