Researchers in China have developed a new method to produce raw materials for plastics and rubber directly from a mixture of hydrogen and carbon monoxide (syngas). The study is regarded as a significant step that could reduce the carbon footprint of fossil fuel-based polymer production.
Today, olefins, which are the raw materials for plastic and rubber products, are mostly produced from petroleum. This situation increases production costs and places the sector under a heavy carbon burden.
Although scientists have long been researching more sustainable alternatives like syngas, existing methods have not been commercially viable due to inefficiency.
The research revealed that a new iron-based catalyst increases olefin production efficiency from syngas by 50%. This development holds the potential for a major transformation in the chemical industry.
Scientists used the Hydrogen Atom Economy (HAE) value to measure efficiency. Previous methods had low HAE because they removed water formed as a byproduct from the reaction.
The new catalyst instantly reconverts this water back into hydrogen, incorporating it into the reaction and eliminating efficiency losses.

According to the research:
- Sodium-modified iron-coated nanoparticles rapidly convert water into hydrogen.
- The produced hydrogen re-enters the reaction, increasing olefin formation.
- The need for additional hydrogen supply decreases.
- Waste production is reduced by 46%.
The catalyst was also found to operate stably for 500 hours.
The new method not only improves efficiency but also:
- Reduces steam consumption,
- Decreases wastewater generation,
- Limits CO2 emissions.
This development is considered a potential breakthrough that could significantly reduce the carbon footprint of the plastics and rubber industry.
