PNNL develops novel catalyst to convert ethanol into C5+ keytones

November 11, 2020 |

In Washington state, scientists at Pacific Northwest National Laboratory (PNNL) have developed a novel catalyst that converts ethanol into C5+ ketones that can serve as building blocks for everything from solvents to jet fuel. In a new paper, they describe this breakthrough chemistry and the mechanism behind it.

The catalyst developed at PNNL condenses multiple reactions into a single step. Ethanol meets the catalyst under high temperature (370°C, or 698°F) and pressure (300 pounds per square inch). It then rapidly converts to products containing more than 70 percent C5+ ketones. The catalyst also appears robust, remaining stable over 2,000 hours of use. The end goal is to have a catalyst that can last for 2 to 5 years.
