Chinese scientists successfully synthesize paraxylene from carbon dioxide

Researchers from Anhui University of Technology have developed a new catalyst that successfully synthesizes paraxylene directly from carbon dioxide and hydrogen, and has broken the world record for single-shot production efficiency of this type of catalyst.

Paraxylene, commonly known as PX, is a key raw material for the production of chemical products. Currently, the industry mainly relies on processing heavy petroleum to produce PX, but this method consumes a lot of energy and has high emissions. For every ton of PX produced, about 4 tons of oil are consumed, and about 3 tons of carbon dioxide are emitted.

According to experimental data, using 1 kg of this catalyst to work continuously for one day can produce more than 1 kg of PX.
