Oak Ridge scientists convert plastic waste into gasoline using molten salts

ORNL researchers report a low-temperature, catalyst-light process that turns polyethylene into gasoline- and diesel-like fuels at nearly 60% yield.

What to know

  • ORNL's process converts polyethylene into gasoline- and diesel-like fuels at about 60% gasoline yield using molten aluminum chloride salts as both reaction medium and catalyst.
  • The reaction runs below 200°C, far milder than the 450-500°C typically required by conventional pyrolysis-based plastic-to-fuel methods.
  • The method avoids noble-metal catalysts, external hydrogen, organic solvents, and chemical initiators, potentially simplifying and cheapening the process.
  • Findings are published in the Journal of the American Chemical Society and a patent application has been filed; scaling beyond lab experiments remains untested.

“We converted polymer waste to value-added fuels by using commercially available inorganic salts as the reaction media to provide the catalytic sites.”

    Mastodon user questions society's response to plastic waste

    A Mastodon user reacts skeptically to the plastic-to-fuel news, questioning whether such technology will actually be adopted to address plastic waste.

    “Maybe we can figure out what to do about all that plastic waste? But hey, maybe not that?”

    ORNL publishes plastic-to-gasoline conversion study

    Oak Ridge National Laboratory researchers describe a method using molten aluminum chloride salts to convert polyethylene into gasoline- and diesel-like fuels at about 60% gasoline yield under mild conditions below 200°C, published in the Journal of the American Chemical Society; the team has applied for a patent.

    “Unlike traditional techniques for converting polymer to fuel, the new process did not require noble-metal catalysts, organic solvents or external hydrogen.”
