Oak Ridge National Laboratory researchers have developed a new catalyst for converting ethanol into C3+ olefins鈥攖he chemical building blocks for renewable jet fuel and diesel鈥攖hat pushes the amount produced to a record-high 88%, a more than 10% gain over their previously developed catalyst.

Increasing the yield from this conversion can advance cost-effective production of renewable transportation fuels.

In the search for new catalysts, ORNL's Zhenglong Li achieved the record yield by exploring a new reaction pathway using a metal mix of copper, zinc and yttrium. His experiments add to fundamental understanding of how various metals behave in complex while also indicating potential for developing new catalysts and reducing carbon deposits that decrease yield in the catalysis process.

The new research builds on previous work with a conversion process now licensed to Prometheus Fuels and more recent research using a zinc-yttrium beta catalyst combined with a single-atom alloy catalyst.
